Ultrasonic gas meters, compared to traditional mechanical gas meters such as diaphragm or turbine types, offer a wide range of clear advantages, making them particularly suitable for applications that require smart gas management, high measurement accuracy, and long service life.

By utilizing the time-of-flight principle of sound waves, ultrasonic gas meters achieve a measurement accuracy of ±1.5% or better, and maintain stable performance even at low flow rates—ideal for precisely metering small gas consumption, such as minimum flow in households. Since there are no moving parts, there is no mechanical wear, which ensures a service life of more than 15 years without the risk of aging or jamming commonly found in traditional meters.

Ultrasonic gas meters require minimal maintenance, as they do not contain consumable components like gears or diaphragms. Their rapid response—typically within milliseconds—makes them effective in detecting sudden gas usage and anti-tampering scenarios. With a streamlined internal flow path, they cause extremely low pressure loss, improving overall energy efficiency and enabling use in high-flow environments.

These meters support integration with NB-IoT, LoRa, or 4G communication modules, allowing for remote data collection, smart valve control, prepaid metering, and consumption analysis. Their sealed design offers excellent resistance to dust, moisture, and low temperatures down to -25°C or lower, making them well-suited for outdoor and cold-region installations without internal condensation issues.

In addition, ultrasonic gas meters often include self-diagnostic features to detect abnormal conditions such as gas leakage, reverse flow, or incorrect installation, helping users quickly identify and resolve problems. They are also compliant with international metering standards like OIML R137 and MID, making them suitable for global markets.

Typical application scenarios include smart residential gas metering, commercial users such as restaurants and heating systems, city gas network management, and industrial gas measurement—particularly for natural gas.
