Movable U Tube Flowmeter

Abstract

A movable U tube flowmeter is a type of movable tube flowmeters which is not based on Bernoulli's theorem and hence it enables us to measure flowrate regardlessly of viscosity losses. The movable U tube of this flowmeter is connected with a fixed inlet and on outlet tube by two bellows. The shape of the U tube is arbitrary. Some typical devices of a movable U tube flowmeter are examined experimentally. Experimental results show fairly well that the theoretical considerations of a movable U tube flowmeter are correct for all devices examined.
