Scope
Main technical content: Ultrasonic flowmeters measure the relationship between the time of ultrasonic wave propagation in a gas medium and the flow rate. The time difference between the ultrasonic wave propagating in the same direction and the opposite direction in the gas medium is proportional to the average flow rate of the gas medium. By calculating the relationship between the time difference of ultrasonic wave propagation and the propagation distance, the flow rate of the gas medium can be obtained. By multiplying the flow rate by the cross-sectional area of the flowmeter pipeline, the flow of the gas medium can be obtained. Ultrasonic flowmeters have input signal processing functions: flow, temperature, and pressure; output functions: pulse frequency, data communication, and alarm functions. Since the workplace is a flammable and explosive gas environment and may be indoors or outdoors, ultrasonic flowmeters have explosion-proof functions and shell protection functions, etc.
