What is Dual Pulse Flowmeter Fidelity Checking about?

The document discusses dual pulse fidelity checking performed by OMNI Flow Computers to reduce measurement uncertainty from added or missing pulses. It monitors two pulse trains (A and B pulses) from turbine or positive displacement flowmeters for differences. It detects but does not correct ambiguous errors like isolated missing or added pulses. It rejects simultaneous pulses on both trains likely from noise and corrects for total failure of one train. Maintaining clean, low impedance pulse signals is impo
