Feasibility justification for a hybrid ultrasonic flowmeter for natural gas

Abstract

The possibility of creating a hybrid ultrasonic flowmeter of natural gas is presented, which combines a fourchannel ultrasonic transit-time method (TOF) and a resonance method. A mathematical description of such a flowmeter is given, the errors of the classical and the proposed flowmeter are estimated, the gain in accuracy and resistance to external factors are shown.
