In modern industrial production, flow meter is an essential instrument, which can accurately measure the flow of fluid in the pipeline, and provide important help for the operation management of production equipment and the control of product quality. This article will focus on the working principle of gas flow meter, so that you can have a deeper understanding of the measurement function and performance of the flow meter. The principle of the

gas flowmeter is to convert the flow of the fluid into a standard signal output by relying on a specific measuring element. This signal can be acquired and processed to obtain an accurate flowmeter value. Gas flow meter is the use of infrared, thermistor, pressure sensor and other technologies to achieve flow measurement.

first introduced the infrared flowmeter. The working principle of the flowmeter is to measure the number of suspended solids or bubbles in the fluid through an infrared sensor, and then calculate the flow value. Infrared flowmeter is mainly used to measure the flow of gas. Its advantage is that it can avoid flow errors caused by factors such as range and material.

The second type of gas flow meter is a thermistor flow meter. Its working principle is to measure the flow by measuring the temperature change when the fluid passes through the thermistor. The thermistor flow meter has high accuracy and can withstand high pressure and high temperature. The environment can also be applied to the measurement of high concentration gas flow. The

is finally a pressure sensor flowmeter, which uses a pressure sensor to measure the pressure difference generated when the fluid flows in the pipeline, and then calculates the flow rate. The pressure sensor flowmeter is suitable for the measurement of various gas flow, and is simple and easy to install and maintain, and is widely used in the field of industrial automation control.

understanding the principle of gas flow meter is very necessary for flow measurement in modern industrial production. Different types of flowmeters are different in terms of measurement principle, measurement range, accuracy and installation methods. It is very necessary to choose a flowmeter suitable for your own situation according to actual needs.
