Technical Field

[0001] The utility model relates to the technical field of gas ultrasonic flow sensors, in particular to a gas ultrasonic flow sensor. Background Art

[0002] A gas ultrasonic flow sensor is a sensor used to measure gas flow. It uses ultrasonic technology to measure the velocity and volume of gas flow, thereby calculating the gas flow rate. A gas ultrasonic flow sensor is usually composed of a transmitter and a receiver. The transmitter emits an ultrasonic signal, while the receiver receives the signal and converts it into an electrical signal. By measuring the propagation time of the ultrasonic signal and the frequency change of the received signal, the sensor can calculate the flow rate and volume of the gas. The gas ultrasonic flow sensor has the advantages of high accuracy, fast response, no pressure loss, and no influence of gas density changes. It can be widely used in industrial process control, natural gas metering, gas metering and other fields. However, there are also some limitations to the gas ultrasonic flow sensor. For example, the sensor is sensitive to environmental factors such as gas temperature, pressure and humidity, which may affect the measurement results. In addition, the speed and characteristics of gas flow will also affect the measurement accuracy of the sensor. In general, the gas ultrasonic flow sensor is a reliable and accurate gas flow measurement tool suitable for a variety of application scenarios.
