Ultrasonic Gas Meter
The ultrasonic gas meter is a fully electronic meter that measures gas flow by detecting the time difference of ultrasonic waves traveling through the gas medium. It features high adaptability, exceptional stability, superior measurement accuracy, and real-time temperature and pressure compensation. Additionally, it boasts advantages such as compact size, no moving parts, long-term operational precision, and an extended measurement range. Its performance meets the requirements outlined in JB/T 12958 "Household Ultrasonic Gas Meters" and GB/T 39841-2021 "Ultrasonic Gas Meters."
