An ultrasonic open channel flowmeter

Abstract

The present application relates to flow meter related technical field, specifically disclose a kind of ultrasonic open channel flow meter, including shell holder, first unfolding mechanism and second unfolding mechanism, the first unfolding mechanism drives main frame plate and automatically overturns and unfolds or folds in shell holder, the main frame plate can be folded and stored into the shell cavity of shell holder, the second unfolding mechanism drives secondary frame plate and automatically overturns and unfolds or folds in main frame plate, and second unfolding mechanism also linkage drives sleeve holder and automatically overturns and unfolds or folds in secondary frame plate, the ultrasonic generator being set on it can be folded and stored into the frame cavity of secondary frame plate, and secondary frame plate can be folded and stored into the frame cavity of main frame plate with sleeve holder.The ultrasonic open channel flow meter, when not working, can be folded and stored automatically, form protection, avoid external environment to cause damage influence, effectively reduce maintenance cost, in addition, realize multi-channel measurement, improve measurement accuracy.
