The GB-1.6/2.5 Class B micro ultrasonic gas meter uses advanced ultrasonic measurement technology to detect gas flow accurately and reliably. Gas passes through the aluminum alloy chamber, where piezoelectric sensors capture flow signals and convert them into electrical signals. These signals are processed by a built-in microprocessor for measurement, calculation, display, and data storage.

Designed with a compact structure and durable materials, the meter offers accurate measurement, stable performance, and high reliability under long-term operating conditions. It is suitable for use in natural gas, liquefied petroleum gas (LPG), and other clean gas measurement applications.
