Спосіб вимірювання витрат рідини в трубопроводі

Abstract

A method for measurement of flow rate of liquid in a pipeline includes preliminary heating of liquid with a special heater, measurement of difference of temperatures of liquid before and after heater. Measured temperature difference is transformed to frequency information signal, with its registration at the output from the circuit, value of gas flow rate is determined by change of frequency of that information signal.
