The flowmeter is mainly composed of a flowmeter body, an ultrasonic transducer and its mounting parts, a signal processing unit and a flow computer. For contact and externally clamped flowmeters, the field pipe where the transducer is installed can be used as a pipe section.
The transducer of the contact flowmeter is directly in contact with the measured body, and the transducer of the external clamped flowmeter is tightly installed on the outer wall of the pipeline.
Ultrasonic flowmeter is mainly composed of ultrasonic generator, ultrasonic receiver, electronic circuit, flow display, accumulation system. Among them, the ultrasonic generator is mainly used to generate ultrasonic waves and emit them into the fluid; The ultrasonic receiver is mainly used to receive ultrasonic waves after passing through the fluid; After the ultrasonic wave is received, the flow is transmitted to the display screen in the form of an electrical signal after being amplified and converted by the electronic circuit. The cumulative system completes the cumulative calculation of traffic.
Ultrasonic flowmeters use the principle of sound velocity propagation to determine fluid velocity. The speed at which sound waves travel through a liquid is known and is usually a constant value. By measuring the propagation time of the sound wave signal in the liquid, the traveling distance of the sound wave in the fluid is calculated, and the flow rate of the fluid is obtained.
Ultrasonic flowmeter has the advantages of high measurement accuracy, no direct contact with liquid, not easy to be affected by the medium, and is widely used in chemical industry, water treatment, oil and gas and other industries. Through the ultrasonic flow meter, we can accurately understand the flow of liquid in the pipeline, find problems in time and solve them, ensure the smooth progress of the production process, and provide a strong guarantee for the efficient operation of industrial production.
