ABSTRACT:
An open-channel liquid flowmeter which is not disabled by submergence of the primary device measures flowrate using both critical-flow and velocity-area techniques and compares results to determine the conditions of flow. The device then selects the method offering the greatest probability of accuracy at that moment and computes flow using the selected method.
