Measurement of Flow Output by Strain Gauge Transmitter

In general, load cells are used to measure powder and grain flow in a system utilizing a hopper. In this case, weight of powder transferred to the hopper is calculated by the difference between initial (empty) hopper weight (X1) and final weight of filled hopper (X2), by the system illustrated below:

[Procedure] 1) Before the hopper is filled, Memory Switch of the Track/Hold is turned on in order to hold initial weight (X1). 2) The Math Function Module determines actual weight of the load by equation X0= X1- X2. 3) Finally, Memory Switch of the Track/Hold is turned off, X1 becomes equal to X2, and X0 returns to 0.
