Are ultrasonic gas meters better than diaphragm gas meters

From the working principle: Diaphragm gas meters use the physical diaphragm principle to measure gas volume through repeated expansion and contraction of the gas and diaphragm. Ultrasonic gas flow meters measure the relationship between the propagation speed of sound in gas and the gas flow rate.

From the perspective of measurement accuracy: the accuracy range of traditional diaphragm gas meters is relatively narrow, usually between 1.5 and 2.5. On the other hand, the accuracy range of ultrasonic gas meters is usually between 0.5 and 1.0 due to the use of high-precision acoustic sensors. With the development of computer technology and microelectronics technology, diaphragm gas meters have become intelligent, and their accuracy is almost comparable to ultrasonic gas meters.

From the perspective of service life: Diaphragm gas meters usually have a long service life and can run for 10 years. However, due to the use of complex electronic components, the service life of ultrasonic gas meters is relatively short, usually 5-8 years.

From the perspective of applicable scenarios: Because ultrasonic gas meters have the advantages of high accuracy and good stability, they have been widely used in situations that require high-precision measurement and safety management. Diaphragm gas meters are suitable for occasions where the accuracy of the instrument is not high, such as civil gas metering. To sum up, when choosing a gas meter, it’s hard to say which one is better. It is necessary to consider the actual application environment and requirements for accuracy and safety, and select an appropriate gas meter to ensure measurement accuracy and safety.
