Problems solved by technology

[0003] The above-mentioned technical solutions all add a fixed diversion structure in the flowmeter housing. Since the diversion structure is fixed, it can only slow down the turbulence as a whole, but cannot dynamically adjust it according to the current fluid situation, and the effect of stabilizing the flow is poor.
At present, there is no ultrasonic flowmeter that can dynamically adjust the deflector to achieve effective and stable flow according to the vibration data of the fluid in the ultrasonic flowmeter. Therefore, an ultrasonic flowmeter with adjustable deflector is proposed.

Abstract

The invention discloses an ultrasonic flow meter with adjustable flow deflectors. The ultrasonic flow meter comprises an ultrasonic flow meter shell, an ultrasonic transducer, reflecting sheets below the ultrasonic transducer and a reflecting sheet bracket, the flow deflectors are arranged in an ultrasonic propagation cavity between the two reflecting sheets, a fluid vibration detector and a flow deflector adjusting device are arranged on the flow deflector, the fluid vibration detector is used for acquiring fluid vibration data, and the flow deflector adjusting device is used for adjusting the position and / or angle of the flow deflector according to the fluid vibration data. According to the ultrasonic flowmeter, the flow deflector is dynamically adjusted according to vibration data of fluid in the ultrasonic flow meter to achieve effective flow stabilization.

Description

technical field [0001] The invention belongs to the technical field of intelligent ultrasonic flowmeters, in particular to an ultrasonic flowmeter with adjustable deflectors. Background technique [0002] The emitter supports of ultrasonic flowmeters currently on the market mainly include plastic support, column and plate structures, but these structures have the problems of high sensitivity to water flow and poor stability. Once severe turbulence occurs, the product flow parameters will be unstable. Existing ultrasonic flowmeter schemes for steady flow, for example, the Chinese patent "Ultrasonic Water Meter, Heat Meter Flow Sensor" with publication number CN101576399A proposes ultrasonic water meter, heat meter flow sensor: including sensor housing, ultrasonic transducer, located in The reflector at the bottom of the ultrasonic transducer is characterized in that a rectification tube is placed in the center of the sensor housing, and rectification corrugations are formed ...
