1. Instantaneous Flowrate Calculation
The signal delivered by the load cell(s), which represents the weight per unit length of
the belt(kg/m), is multiplied by the signal delivered by the speed sensor which
represents the belt speed (m/s). The result of this operation is the instantaneous
flowrate (kg/m x m/s=kg/s) which is then multiplied by suitable constant to obtain the
value in the required engineering units (kg/h or ton/h, etc.). An adjustable damping
filter is provided separately for displayed rate and current outputs.
2. Flow Totalization
The total is accumulated by multiplying mass per unit length by incremental length
and totalizing the result in engineering units.
3. Zero and Span Automatic Calibration
Zero and span calibrations are based on belt length defined by a number of belt
revolutions.
To calculate the exact number of revolutions, the instrument counts the pulses
delivered by the speed sensor (one pulse represents a specific belt length); when the
required number of pulses is reached, the instrument ends the calibration test, and
compares the actual totalized value to the theoretical one (0 for zero calibration), and
calculates the calibration constant.
The calibration constant is a calculated value that can be factored based on an actual
material test.
· Electronic Calibration (R-Cal)
Allows the operator to perform the calibration without the need of applying test
