What are the common failure factors of ultrasonic flowmeters

What are the common failure factors of ultrasonic flowmeters? An ultrasonic flow meter is an instrument that measures flow by examining the effect of fluid flow on an ultrasonic beam (or ultrasonic pulse). According to the inspection method, it can be divided into different types of ultrasonic flow meters such as propagation velocity difference method, Doppler method, beam offset method, noise method and correlation method. Ultrasonic flowmeter consists of three parts: ultrasonic transducer, electronic circuit and flow display and accumulation system. The flow measurement accuracy of ultrasonic measuring instruments is almost unaffected by the temperature, pressure, viscosity, density and other parameters of the measured fluid. It can also be made into non-contact and portable measuring instruments, so it can solve the problems of strong corrosion, corrosion, etc. that are difficult to measure with other types of instruments. Problems in force measurement of non-conductive, radioactive and flammable and explosive media. Ultrasonic flowmeters can be installed outside the pipe and measure flow non-contactly. The cost of the meter is basically independent of the diameter of the pipe being measured. It is a better flow measurement instrument for large pipe diameters. Moreover, the ultrasonic flowmeter does not need to install a measuring element in the fluid, so it will not change the flow state of the fluid and generate no additional resistance. The installation and maintenance of the instrument will not affect the operation of the production pipeline.
