Accuracy
± 1 % of full scale, higher accuracy with linearizing function of integrator
Accuracy subject to: On factory approved installations the flowmeter system’s totalilzed 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 at least ten minutes running time.
