Abstract

This paper describes a remote measurement method for estimating unsteady flowrate through a pipeline. By this method, instantaneous flowrate at the remote location along a pipeline (distance L) from flowmeters is measured by making use of dynamic characteristics between two cross sections of the circular pipeline. Using this method, instantaneous flowrate is accurately measured at a location where it is difficult to setup flowmeters. The estimated flowrate waveforms by the method are compared with directly measured ones by cylindrical choke-type instantaneous flowmeter. The validity of the method is established.
