Specifications

Accuracy ± 0.5% to 0.25%
Accuracy subject to: On factory approved installations, the weighfeeder system's totalized weight will
be within the specified accuracy when compared to a known weighed material test sample. The test
rate must be within the specified range of the design capacity, and held constant for the duration of
the test. The minimum material test sample must be equivalent to a sample obtained at the test flow
rate for three revolutions of the belt, or at least ten minutes running time, whichever is greater.
