Accuracy subject to: on factory approved installations the flowmeter 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 dura-
tion 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.
