Ultrasonic gas flow meter-related knowledge

Here first borrowed from a person in the industry: If NB-IoT technology is to let the gas meter insert the wings of intelligent communication, then ultrasonic metering technology is to inject the core muscle group for the gas meter, in the measurement technology has been essentially improved, for the intelligent application of the gas meter provides a greater space. In addition, because it is fully electronic, has no mechanical parts is not affected by mechanical wear and tear, failure, Ultrasonic gas flow meter reliability, and improves a lot. Ultrasonic gas flow meter small size, lightweight, good repeatability, small pressure loss, not easy to age, long service life; intelligent, fully electronic structure, can be extended to prepaid meter or wireless meter reading function. Here are some answers.

Understanding the Ultrasonic gas flow meter.

An Industrial ultrasonic gas flow meter is mainly composed of a transducer and converter, it is a kind of flow meter developed based on the principle that the propagation speed of ultrasonic waves in the flow medium is equal to the vector sum of the average flow speed of the measured medium and the speed of the sound waves in the stationary medium, there are different types such as Doppler method, beam shift method, velocity difference method, noise method, and correlation method. According to the principle of signal detection, and Ultrasonic gas flow meter can be divided into propagation speed difference method (direct time difference method, time difference method, phase difference method, and frequency difference method), beam offset method, Doppler method, mutual correlation method, spatial filter method, and noise method, etc. Our time-difference intelligent ultrasonic gas meters: measure the time difference caused by the difference in propagation speed when propagating downstream and upstream to calculate the measured fluid velocity. It uses two acoustic transmitters (SA and SB) and two acoustic receivers.

Features of the Ultrasonic gas flow meter.

The Ultrasonic gas flow meter's digital signal processing technology makes the meter's measurement signal more stable, resistant to pressure, and more accurate in measurement. No mechanical drive components to break down easily, maintenance-free and long life. More optimized circuitry and high integration; low power consumption and high reliability. Intelligent standard signal output, friendly human-machine interface, and a variety of secondary signal output, for you to choose at will. The small pipe diameter measurement is economical and convenient, with high accuracy.

Smart ultrasonic gas flow meter commonly used piezoelectric transducer, it uses the piezoelectric effect of piezoelectric materials, using the appropriate emission circuit to add electrical energy to the piezoelectric element of the transmitting transducer, so that it produces ultrasonic vibration. The ultrasound waves are propagated at an angle into the fluid and are then received by the receiving transducer and turned into electrical energy by the piezoelectric element for detection. An Ultrasonic gas flow meter is accurate, stable, and easy to operate, it has a very simple installation, no need to break the pipe, no need to stop the water, is mostly used for large pipe flow measurement, easy to use so that customers can easily achieve flexible pipe flow measurement.
