Introduction
The Belt-Way conveyor belt scale is a highly accurate and cost effective in-
motion weighing system. It is designed to measure material flow over a
conveyor belt in real-time. The primary components are the integrator (AKA,
controller, display, indicator), load cell assemblies, and speed sensor. The
scale system processes speed and load signals to accumulate weight and
calculate flow rate.
This manual covers the following belt scale models:
•Model 45, Model 50 (Low capacity)
•Model 100, Model 150, Model 200 (Medium capacity)
•Model 350, Model 500, Model 1000 (High Capacity)
This manual pertains to scales operating on firmware 6.43 and above.
A manual for previous versions may be found at beltwayscales.com

Scale Accessories
The Belt-Way conveyor belt scale works with a range of accessories
designed to maximize accuracy, efficiency, and safety.
Visit beltwayscales.com or call us today for a complete list of all the
accessories that Belt-Way has to offer.
•Angle Sensor
The angle sensor eliminates the need for constant recalibration
when the scale is installed on a variable angle conveyor or portable
machine.
•Junction Box
A junction box can be installed on the conveyor to place
the scale integrator up to 1000 ft. from the scale.
•IO Board
The IO board allows the scale to interface with a PLC system, automate
loadout of trucks and rail cars, or control a VFD to blend multiple
products.
•Outdoor Protection Enclosure
Heavy duty enclosure offers extra protection for the scale integrator.
Includes power switch.
•Wireless Multi-Scale Remote Display
The remote display allows multiple scales to be viewed from one
location. Monitor production, clear weight, and perform zero calibrations.
Wireless communication makes installation simple and cost effective.
•Plant Connect - Online Scale Production Reporting
Our Plant-Connect website allows users to monitor belt
scale production on a PC, tablet or smart phone.

Mechanical Installation
2D component and installation drawings are available at beltwayscales.com
3D drawings are available by request.
A. Recommended Tools
▪Cutting torch and grinder (remove idler mounting feet)
▪Heavy duty drill or magnetic drill press (drill u-bolt holes)
▪Tape Measure (measure idler distance)
▪Angle finder or phone app (measure conveyor angle)
▪1/2”socket and wrench (load cell and speed sensor brackets)
▪9/16” deep socket and wrench (V-block, u-bolts, leveling bolts)
▪String (to level weighbridge idlers)
▪Shim kit (to adjust idler height)
▪4 way screwdriver (integrator mounting, integrator door, hose clamps)
▪Small Belt-way screwdriver (integrator wiring)
B. Conveyor Design Recommendations
The following design suggestions are essential for best scale accuracy and repeatability.
▪Reduce speed whenever possible to maximize belt load. Slow moving, heavily loaded belts
work better than fast moving, lightly loaded belts.
▪Proper belt tension must result in 1%-2% deflection between idlers.
For example, 2% deflection is 1 inch sag in the belt over a 4 ft. idler spacing.
▪Lower trough angles, 0-35, are preferred. Avoid 45troughed idlers.
▪Install a belt scraper to keep the belt clean.
▪Cover the conveyor to shelter it from wind, rain and snow.

C. Scale Placement
▪Install the scale where it is easily accessible for maintenance purposes.
▪Choose a very rigid section of conveyor such as an idler over a brace.
▪Avoid curves in the conveyor.
▪Stay at least three idlers away from the head pulley, tail pulley, and loading points.
Material must not impact the belt near the scale!
D. Define the Weighbridge
▪The weighbridge idlers must be in good mechanical condition.
▪The weighbridge idlers must be the same trough angle, and diameter.
▪The weighbridge idlers should be an equal distance apart.
▪Skirting should not make contact with the belt in the weighing area.
▪A single idler weighbridge consists of 5 idlers.
Scale must be installed on the center idler
▪The dual idler weighbridge consists of 6 idlers.
The scale must be installed on the 2 center idlers.

E. Attach Load Cell Assemblies to idler
▪Bolt the load cell assemblies to the idler as shown using the “V-Block”.
▪The load cell cable should point downhill.
▪Leave plenty of clearance between the load cell assembly and conveyor frame.
▪Do not overtighten the V-Block bolts.
▪The bolts should be tightened ¼ turn after compressing the lock washer.
▪Position the load cell assemblies an equal distance from the conveyor frame.
▪This balances the load of the belt evenly between the load cells.
NOTE: Stainless Steel Load Cells –Do not use a full thread bolt,
or over tighten the existing V-Block bolt on a stainless steel load cell.
This will damage the load cell cable.

F. Install Scale Support Pipes
This step is extremely important to ensure long term scale accuracy.
▪The mounting pipe must touch the strap on the uphill side of load cell assembly.
▪The strap on the downhill side must create an oval opening.
▪Center the pipe in the oval hole.
▪The load cell assembly must be free to move up and down slightly on the pipes.
This eliminates torque on the conveyor frame, which allows automatic alignment
of the weighing elements.
▪Install the four hose clamps onto the pipe with the screw fitting directly over the
top of the pipe, but do not tighten the clamps at this time.
Uphill side:
Retaining strap
fits tightly around the pipe.
Downhill side:
Retaining strap
forms oval hole around the pipe.

G. Drill U-bolt Holes
▪Use the leveling plate as a drill template for the U-bolts.
▪The centers of the leveling plates and pipes should measure 15”apart.
▪The holes should be at least 7/16” to clear the 3/8” -16 U-bolts.
H. Remove and Modify Idler
▪Unbolt idler from frame.
▪Remove the idler mounting feet to create clearance above the conveyor frame.
▪If the idler feet are not removed, all other weighbridge idlers must be shimmed up 3/8”.
▪Ensure the idler is centered on the conveyor.

I. String-Line Idlers to level the Weighbridge:
This is an extremely important step in the installation process.
▪The empty belt must rest uniformly on all idlers within the weighbridge.
▪Use a minimum of three strings to align all 5 or 6 weighbridge idlers.
▪Shim idlers if necessary to bring them into alignment.
▪Use the 3/8-16 leveling bolts to adjust the scale idler height
▪Tighten U-bolts evenly so pipes remain parallel and oval clearance
around bottom pipe is maintained.
▪Tighten the jam nuts against the leveling plate to lock the pipes in place.

J. Install Hose Clamps:
▪Install the hose clamps on the outside of the load cell
assembly.
▪Leave clearance so the clamps don’t bind between the
pipe and load cell bracket.
▪Rotate the screw barrels away from the gaps between
the hanger brackets and the pipes.
K. Install Speed Sensor Assembly
▪The standard speed sensor assembly may hang
from either pipe. It must point downhill.
▪The wheel must ride smoothly on the belt.
▪Avoid installing it near return idlers that may cause the
wheel to bounce.
▪A small amount of weight may be added to the speed
wheel arm to hold the wheel firmly on the belt.
▪Use two hose clamps to retain the mounting arm .
▪Secure the cable to the arm with cable ties. Route the
cables carefully along the conveyor frame so they are
protected from falling debris and pinch points.
L. Optional Angle Sensor
Any conveyor that frequently changes angle must have an angle sensor installed.
▪Mount the Angle Sensor directly on the conveyor frame.
▪Mount in the direction of the head pulley.
▪Reference the UP arrow indicator on the sensor.
Caution: Excessive vibration
will interfere with Angle Sensor
performance.

Always disconnect power before servicing the integrator!
Make sure you LOCK OUT, TAG OUT and TRY OUT the electrical system before any maintenance
or service. Please follow all Federal, State and Company Safety procedures and policies when
working with this product.
Integrator Installation
Leave a minimum of 3”clearance on the hinge side to allow the door to open. The mounting kit
includes four mounting feet and four M6 x 1mm x 60mm screws with nuts to attach mounting feet
to the Integrator. Customer must supply fasteners from mounting feet to mounting location.
The integrator is weatherproof but should be installed in a
protective enclosure whenever possible.
Physical damage to the integrator is not covered under warranty.
Do not install the integrator where it is subject to vibration.
Damage from vibration is not covered under warranty.
WARNING!
Rubber or neoprene should be used to dampen the
effects of vibration. This is especially important on
portable machines. Vibration Mounting Kits are
available from Belt-Way.
