Examine for Sensor Damage
Flow Scale is sent from the Factory with the Plate Positioning Bolt driven all the way into the Scale Cavity and the Impact Plate secured against the feed throat wall. (Figure 3)
Shipping Flow Scale:
1) SHIPPING BOLT: The Flow Scale has a heavy plate that can swing free, if allowed, which may cause sensor damage. When moving or shipping, properly screw in the Shipping Bolt so plate is secured tightly against far wall. Lock down shipping bolt with lock nut. When moving-shipping flow scale, lock down Plate to prevent sensor damage.
2) TYRAP (3/8” WIDE X 18” Long) .. Tyrap protects Telfon Sleeves from being damages during shipping especially when scale is laid on it’s side. The Diamond Hanger attached to the Steel Plate can easily smash the Teflon Sleeve. The Teflon sleeve is used to keep the Diamond Hanger from contacting the Knife Suspension Bolt. If the sleeve is damaged and when the Hanger comes in contact with the sleeve, scale accuracy is compromised because hanger will not slip on the sleeve as easily.
Receiving Flow Scale:
Shipping bolt .. In order to calibrate after scale has been in transit; Back off the Shipping Bolt and Lock Nut tighten so the plate rests on the Load Cell Protrusion Rod.
Flow Scale Placement
Mount as vertical as possible. If a slight slant is necessary, make it lean in the direction of the Material Entrance Port (Feed Throat) or away from the Material Entrance Port (not from side to side).
Like any scale, excessive vibrations must be isolated. DO NOT Firmly Mount Flow scale to an agitating piece of equipment like a pug mill, mixer, screen, etc.
Scale Discharge Transition … Important: Fabricate a tapered Square to Round transition
Scale Discharge opening is usually 8” or 10” square. The product is evacuated from the scale between the plate and the feed throat wall. Especially with sticky or chunky product, the product flow through this area must be clear of any restrictions.. i. e. When manufacturing an 8”square ID to round pipe transition, a 9” ID round pipe has been flanged to the bottom of the 8” square Scale Discharge. The round pipe has cut the corners on the square discharge and restricted flow. Important: Fabricate a tapered Square to Round transition
Regarding: Scale Discharge Transition too small and restrictive… Solution.
A) When discharging material from the flow scale into a round pipe; The Immediate (Bad) Transition illustrates a discharge too restrictive. The Gradual discharge is recommended and can be purchased as an option.
B) When discharging into an open area when flow scale discharge is sitting on a plate; situate the flow scale over a square hole the same size as the inside diameter of the scale discharge. See illustration below.
Good
Insufficient Conveyor Discharge Capacity…The Flow Rate of the Discharge Auger or Vane Feeder must always be greater than the charging rate of the Flow Scale. Sudden surges of material shall flood the flow scale and cause inaccurate readings of the scale. Significant flooding of material may lift the weigh plate and unseat the knife from the cradle. The Cradle may have to be reseated by a serviceman.
Display Readout (Integrator) Placement
This Device is used to read the flow rate and the total weight. This readings on this device are regularly and sometimes often (the rate reading at least daily) Zeroed by pressing the F1. This device must be located where the operator has easy access to the observe readings regularly and the manipulate keys. Locate within reach of telephone for factory support.
Set Up Instructions:
Adjust flow scale plate position to the maximum flow rate of the material required. This is best accomplished by unlocking the plate shipping bolt that are used to keep plate from ever swinging excessively hard (destroys load cell) onto load cell protrusion rod during transit.
INITIAL Load Cell Plate Loading Set Up: With protrusion rod drawn all the way back and even with the back wall; position the plate to the back wall, as far from the feed throat as possible. While observing the maximum flow rate through side inspection door, adjust the plate forward until 1 ½ inches short of causing the flow to choke up. Lock down any nuts to keep adjustments secure from vibration.
Adjust the Protrusion Rod Screw forward so plate is forced to slightly slope from the bottom toward the Feed Throat. The load cell signal consequently increases in millivolt dc output reading (green and white load cell wires). As an initial adjustment (Load Cell Plate Loading MV Reading); 10 lb load cell reads about 1.0 to 2.0 millivolts dc…
Impact Plate Position Determination
The Flow Scales can be adjusted to various ranges by the placement of the Plate along the Plate Hanger Rails. General Rule;1) at high rate of flow, the Plate is positioned into the flow of material and as close to the Throat as possible with out causing the plate to choke the flow of material 2) at high vibration amplitude, the plate shall be positioned with an increasing slant.
Once the position has been determined, adjust the flow rate to the lowest flow range expected. Insure all the material easily impacts the plate. If it does not, the plate may not be long enough or the flow range may be too wide for the application.
The Protrusion Rod is always extended so as to place Plate weight on the Load Cell so the Plate still rests on the Load Cell Rod even when the scale may feel some vibrations. Usually the plate is adjusted to a 10 degree (from vertical) slant placed on it by the Protrusion Rod. The adjustment of Plate Adjustment Bolt (Item 102 ) and Protrusion Rod (Item 72 ) affect 1) the slant placed on the Plate and 2) the Material Discharge path (opening between bottom of plate and feed throat wall). A) Too much slant slows down the flow of material. B) Too little of slant may allow Plate vibrations to bounce Plate off the end of the rod (problem.. + vibrations cause flow scale to count up instead of the + and – vibrations cancelling each other out when the plate is in contact with Load cell rod all the time). C) The plate being too far away may not allow all the material to come in contact with the plate. D) The Plate being too close may cause material to back up the flow through the scale.
Once the position has been determined, adjust the flow rate to the lowest flow range expected. Insure all the material easily impacts the plate. If it does not, the plate may not be long enough or the flow range may be too wide for the application. Then Adjust the flow rate to the highest rate expected and confirm that material will not back up into flow scale.
The Protrusion Rod is always extended so as to place Plate weight on the Load Cell so the Plate still rests on the Load Cell Rod even when the scale may feel some vibrations or be bumped. Usually the plate has a 10 degree (from vertical) slant placed on it by the Protrusion Rod.
Plate Adjustment Procedure
1- The Flow Scale is supplied with a 6” and 9” Impact Rods. The 6” rod is used when higher flow rates dictate the Impact Plate be Positioned in an area closer to the Sensor Box Wall than the Throat Wall. The 9” rod is used when lower flow rates dictate the Impact Plate be Positioned in an area closer to the Throat Wall than the Sensor Box Wall. After determining and positioning the Plate for slope and placement; Then lock down Load Cell Protrusion Rod Locknut tight against Impact Sensor by placing wrenches on Impact Sensor and Load Cell Protrusion Rod Locknut. Then lock down Plate Adjustment Bolt (Item 102 ) Locknut tight against Anchor nut on the Plate Assembly Trolley (92).
2- The Plate hangs from a knife edge by the tube attached to the top of the plate. It is important the plate is centered side to side as well as the knife being aligned squarely across Top Dead Center of the inside top of the tube. It is important the plate swings freely on the knife. The knife must align itself in the cradle groove of the Hanger (see below.. item 88 Hanger- – Figure 4B Diamond )
3- Inspect and adjust this after every move (Portable Plant) by removing Top Lid and wrapping your fingers/thumb around the Plate Support Trolley and Hanger tube; lift the tube up and align it ‘s inside Top Dead Center along the knife edge and adjust it with screw drivers through the slots.

Important: 1) Load Cell Wires Must Be Screwed Tight to Terminals at the Indicator and at Scale (notice- capacitor on terminals opposite to green and white wires-place capacitor on terminals as shown-attach load cell stranded wires to stranded wires coming from shielded cable- do not terminate solid wire of capacitor with stranded wire-). 2) Ground the shield at the Indicator Enclosure only. 3) Load Cell, Protrusion Rod, Bracket must be screwed tightly together with Lock Nut.
Operation ..Flow Scale..0-5 to 0-100 TPH … (material density and flow scale size dependant) 10 volts excitation.. about 2.0 mv/volt..
Integrator – Rate Indicator/Totalizer
DSP button toggles display from Rate (TPH) to Totalizer (Tons)
Totalizer is 9 digit and display is 5 digit.. Totals higher than 5 digits flash the indicator between the high digits (4 most significant digits MSD) and the low digits (5 least significant digits).
E.g. h9999 flash to 99.999 = 999,999.999 tons
Daily Operation.. 1) Zero Rate and Totalizer with empty Discharge Augers, Blowers running, etc..2) Make sure Feed Auger, Vane, etc is set to proper speed.
3) Make sure flow scale is reading in proportion to what the speed is reading on Feed Auger, vane, etc. 4) When through weighing, with empty Discharge Augers, Blowers, etc running; make sure Scale Rate returns to Zero. 5) Spot check flow scale with amount used.
Keys -Purpose
DSP toggles the Display between TPH Ton-Per-Hour rate and Tons Totalizer.
When TOT disappears.. Display reads Rate .. TPH,Lbs/Minute,etc
PAR steps the integrator through set up and calibration program.
F1, when pressed for 3 seconds, zeros the flow scale Rate indication.
F2, when pressed for 3 seconds, zeros the flow scale Tons totalizer.

Material Calibration
Plan a method to perform a material calibration by:
1-allowing material sample to flow through the scale at Average Production Rates (TPH),
2-documenting the Scale Totalizer Weight,
3-capturing the sample in a container,
4 - comparing the Flow Scale Totalization Reading with the contained sample on another verifiably accurate scale,
5 – Then adjusting the Span reading of the Dust Flo Scale Integrator.
6- Insure acceptable scale repeatability by running another Material Test.
7- When calibration is successful, perform a Test Weight Rate Reference Procedure for future use. The purpose is easily confirm later that the scale is working properly and still in calibration. After scale usage, the Operator can verify quickly that scale is still in calibration without going to the trouble of a Material Calibration. Test Weight Rate Reference Procedure is performed by hanging a test weight attached by wire to a hook on the backside of the impact plate. Immediately after a complete, successful Material Calibration; it is highly recommended that the Operator documents the rate of a known test weight and compare it to any Test Weight Rate Reference Procedures performed in future. If the Readings at a later date match that of the Test Weight Reading taken after the Material Calibration, then the Operator can be confident the scale is operating properly. When sizing test weights, size a weight to closely to match average production rate.
If Production Rates vary more than 20% plus or minus from the Average Rate calibrated for; consider performing a Multi-Point Calibration instead of only a 2 point Zero and Span Calibration
A Calibration Discharge Gate may be necessary after the Dust Flo Scale in order to capture the sample otherwise measure the amount going into the flow scale.
Calibration Methods
A- Some applications may favor a slide jam gate welded to the underside of an auger downstream of the flow scale.
B- Other applications may favor Calibration Discharge Diverter Tube. The flow scale sits on the Diverter Tube and adds 2 to 3 feet in height to the flow scale. A plate is taken off the Diverted Discharge Port and a Diverter Plate is slid into position and bolted down.
C- Place a known weight in surge/silo, run the material through and make appropriate span corrections.
Material Calibration-installation, plant calibration, accuracy confirmation and troubleshooting
*Zero the Scale Rate (TPH) Indication … no material flowing.. press F1..for 3 sec
*Zero the Scale Totalizer (Tons). press F2 for 3 sec
*Immediately run material through at the rate (TPH) you plan on producing at.
*Document Total immediately (wait for Rate to slowly work down to 0 TPH or Lbs/Minute) after material flow is no longer being measured.
* Compare scale weight with flow scale totalizer weight. If correction is needed, adjust Flow Scale Span calibration by Formula below.
Calibration Scale /Flow Scale X (DSP 2 Value) = New Span DSP 2 Value
Press PAR Button (Program mode), then F1 until, then PAR then ‘dSP2 Value’ and update with New Span Value.
Press PAR until out of the Program mode and into the Run mode

Calibration Confirmation Check. In the future, you can easily check to see if your scale is working right and still callibrated by hanging a reference weight on the plate that will drive the scale rate up to the flow rate normally being weighed. Construct a calibration weight system from a strong fishing leader. Clip the leader to the top of the Plate hanging assembly.
Add fishing weights to the other end. Drape the line down the impact side of the plate and tie of the weight so it lies flat against the bottom portion of the plate. Document the flow rate as indicated on the Integrator. When confirming scale accuracy in the future after re-zeroing scale, drape the weights down the plate in the same manner as draped initially and compare this rate reading with the documented rate reading.
For easy Weight Storage; drape the weights on the non-impact side of the plate
Trouble Shooting
Trouble Shooting Aids
1) Most Necessary Aid ….Telephone in reach of Scale Integrator
2) mv DC meter reading in tenths of millivolt
Symptoms.
Problems.. Corrections.
Zero wanders when no machinery is running.
Load Cell Electro-Mechanical Connections.. Insure that Load cell wires are screwed tightly to terminals. Make sure Load Cell and Bracket and Protrusion
Rod are securely tightened together.
Load cell cable shield has been grounded at both ends .. disconnect ground at scale
Flow Rate deviates above and/or below after being Zero when machinery is running.
Excessive Vibration for the plate angular position setting..Increase angle and/or decrease vibration. Make sure Rubber Protrusion Rod Tip is in place. (Figure 3)
Excessive Change in Vibration…decrease vibration and vibration changes
Excessive Air Flows or changes in air flows.. decrease or eliminate air flows
Plate Hanger is contacting Knife Posts causing free swing of plate to be restricted.. Center the plate between the posts so plate hanger does not contact posts. If plate hanger slides back again, check scale for vertical mounting or excessive vibration. (Figure 5)
Plate Hanger is not seated on knife correctly.. Swing plate an inch or so away from protusuoin rod end. In this position, imagine looking at the plate straight on (Figure 5). Slighty rock the plate back and forth once (left to right if you were able to look at it) so as to lift the hanger slightly of the knife edge. This procedure is usually used to speed up the process of seating knife to hanger. The flow scale being used in the process will find it’s seat.
Flow Rate Zero not properly Zeroed… Before weighing material, allow scale to settle out before Pressing F1. If Scale is zeroed and then scale settles to 2 tph above zero and then the weighing process begins and the scale reads 20tph; the flow rate reads 20 tph while only 18 tph is being added.
Load Cell Electro-Mechanical Connections.. Insure that Load cell wires are screwed tightly to terminals. Make sure Load Cell and Bracket and Protrusion
Rod are securely tightened together.
Bad Load Cell… Check Load Cell. With the plate lifted off the Protrusion Rod, the signal output shall be 0 mvdc. With Plate resting on the Protrusion Rod, the mvdc reading should be near the INP 1 reading programmed into the Integrator. Calibration Weight on the Plate, the mvdc reading should be near the reading documented after the latest Material Calibration. (Figure 3)
Zero Rate oscillates excessively fast around zero making it difficult to read and to zero the rate.
Filter Setting…Increase filter setting on integrator and/or insure Filter Capacitor on Load Cell Signal Wires are tight and/or increase the size of the Load Cell Filter Capacitor.
Observing the Scale Readings, after weighing material with all process machinery still on except scale feeder it is noticed the Rate Indicator has not returned near zero.
Excessive Vibration for the plate angular position setting.. Increase angle and/or decrease vibration.. Make sure Rubber Protrusion Rod Tip is in place. (Figure 3)
Excessive Change in Vibration…decrease vibration and vibration changes
Excessive Air Flows or changes in air flows.. decrease or eliminate air flows
Plate Hanger is not seated on knife correctly.. Swing plate an inch or so away from Protrusion Rod End and gently but abruptly rest the plate against Rod End. Repeat several times and confirm repeatability. If repeatability is a problem; a) swing plate an inch or so away from Protrusion Rod End. In this position, imagine looking at the plate straight on. Slightly rock the plate back and forth once (left to right if you were able to look at it) so as to lift the hanger slightly off the knife edge. This procedure is usually used to speed up the process of seating knife and hanger. The flow scale being used in the process will find it’s seat.(Figure 5) b) Plate Hanger is contacting Knife Posts causing free swing of plate to be restricted. Center the plate between the posts. Caution- moving the plate sides ways put side torque on Protrusion Rod which may cause a zero shift later or it may bend rod and cause it the rod to contact scale body hole wall- Therefore a) have someone lift plate from Rod or b) Take load off of Rod by driving inward temporarily the Shipping Bolt. If plate hanger slides back again, check scale for vertical mounting or excessive vibration. (Figure 5)
Flow Rate Zero Procedure not properly Zeroed… Before weighing material, allow scale to settle out before Pressing F1. If Scale is zeroed and then scale settles to 2 tph above zero and then the weighing process begins and the scale reads 20tph; the flow rate reads 20 tph while only 18 tph is being added.
Protrusion Rod Contacting Flow Scale Wall ..(Page 12) Protrusion Rod Mechanically passes the force applied to the Impact Plate from the weight of the product flow to the load cell. The Protrusion Rod passes through a hole in the wall of the Scale Body. Ensure the protrusion rod is not rubbing against the edge of the hole.
Product building up in Load Cell box..This may impede movement of load cell protrusion rod. a) consider purging the load cell box with a dry air source (call factory about load cell box purging package) b) consider cutting bottom out of load cell box. (Call Factory)
Product Buildup on Plate. Sticky material does not work with this scale. May be caused by sticky product or excessive moisture, etc in the product causing it to be sticky. Possible cures may be to check and fix any air dryer problems for the silo cone air pad for air fluidizing the product (refrigerated air dryer or dessicant dryer) or safely manually cleaning the plate while weighing the product or safely manually cleaning the plate when the process has stopped.
Load Cell Electro-Mechanical Connections.. Insure that Load cell wires are screwed tightly to terminals. Make sure Load Cell and Bracket and Protrusion
Rod are securely tightened together.
Bad Load Cell… (Page 12) Check Load Cell. With the plate lifted off the Protrusion Rod, the signal output shall be 0 mvdc. Plate on the Protrusion Rod, the mvdc reading should be near the INP 1 reading programmed into the Integrator. Calibration Weight on the Plate, the mvdc reading should be near the reading documented after the latest Material Calibration. (Figure 5)
Product Flow Backing up into Scale…Scale not evacuating Product as quickly as it is being weighed. This is many times caused by Scale Discharge Feeder being overwhelmed with too much flow or Scale Discharge Feeder running to slow or Product too sticky or moist or Scale Discharge Transition too small and restrictive.
Flow Scale Accuracy not as expected.
Material Dependant … is make up of material changing flow ability..such as changes in moisture, temperature..
Installation Dependant .. changes in vibration.. erratic air flows..extreme temperature changes
Application Dependant .. significant changes in flow without calibrating at significantly different flow ranges.
Air Current through scale body causing flow of air to negatively or positively influence the force that the plate places on the Load Cell. Seal up covers on scale and use air locks when necessary.
Calibration Sample Size Dependant .. too small of sample to adequately represent accuracy required. Adjust DSP 2 to long term known weight usage.
Inconsistent clearing out scale discharge procedure (augers, etc) after the sample has been run. i. e. Discharging product from Scale discharge auger for 3 minutes sometimes and only one minute other times.
Plate Build Up Dependant… Mid Production Re-calibration and/or Polished plate option.. and/or mid stream rezero .and/or manual and/or Automatic Plate Cleaning Option
Plate Hanger is not seated on knife correctly.. Swing plate an inch or so away from Protrusion Rod End and gently but abruptly rest the plate against Rod End. Repeat several times and confirm repeatability. If repeatability is a problem; a) swing plate an inch or so away from Protrusion Rod End. In this position, imagine looking at the plate straight on. Slightly rock the plate back and forth once so as to lift the hanger slightly of the knife edge. This procedure is usually used to speed up the process of seating knife and hanger. The flow scale being used in the process will find it’s seat. b) Plate Hanger is contacting Knife Posts causing free swing of plate to be restricted.. Center the plate between the posts. If plate hanger slides back again, check scale for vertical mounting or excessive vibration.
Load Cell Electro-Mechanical Connections.. Insure that Load cell wires are screwed tightly to terminals. Make sure Load Cell and Bracket and Protrusion
Rod are securely tightened together.
Material Buildup in the Load Cell Box..
The Load Cell Protrusion Rod passes through a hole in the flow Scale Body. Small amounts Weighed Material Dust may pass through into the Load Cell Box and buildup over time.
This must be check regularly and cleaned away when necessary. The build up of material may impede the slight travel of the load cell rod. The large hole (3” Conduit Cover Hole) is placed to allow dust to escape by falling out through the hole.
Some solutions may be to slow down the flow by taping up part of hole in order to slow down the dust flow being careful not to contact the tape with the threaded rod (Upper Left). Another (Upper Right) may be to cover the large hole with a 3” Conduit Cover and supply pressurized dry air to the air fitting on the bottom of the Load Cell box. Adjust the pressure up until the dust does not flow into the box.
