BELT WEIGHER OPERATING MODE

11.1

Introduction and Overview

eNod4

belt conveyor scale is a device that continuously measures bulk material as it moves along a conveyor. The system

requires two general parameters to operate:



It needs to know the weight of the material being moved along the conveyor belt



It needs to know the speed at which it’s moving along the conveyor belt.

The weight of the material on the belt is determined by weighing a section of conveyor belt loaded with material and then
subtracting the average weight of the unloaded belt. The speed at which the material is moving is determined by measuring
the speed of an idler or wheel in contact with the conveyor belt. The weight and speed is combined to produce a running
total and a rate of flow of material going through the belt conveyor scale. The correct operation of the scale system requires
the components to be installed correctly, periodically calibrated, and properly maintained.

Belt scale operation

In

belt scale

operating mode,

eNod4

continuously calculates the total amount of material that goes through the weighing

system and calculates the flow rate of material instantaneously.
