Introduction

USM-RA/RS Series Ultrasonic Gas Meter is a type of electronic meter that adopts TOF (Time of Speed) principle to measure flow velocity of gas medium. Employing advanced ultrasonic technology, this meter ensures high-precision, wear-free gas flow measurement, providing accurate and reliable results over time. 

With Cubic's advanced algorithm technology, the Cubic ultrasonic gas meter offers excellent adaptability to real gas conditions and can accurately measure natural gas, natural gas with 23% hydrogen (H₂), and LPG.

USM-RA/RS Series integrates seamlessly with GPRS, NB-IoT, and other IoT technologies, facilitating real-time remote monitoring and management. This allows users to effortlessly track gas consumption and monitor the meter's status from anywhere.

Both steel and aluminum case options are available for the gas meter.

Designed to operate effectively in extreme conditions, the USM-RS-L series performs reliably across a wide temperature range from -40℃ to +60℃, making it suitable for even the harsh environments. 

With class 1.5 accuracy and Compliant with MID and OIML, this meter is suited for residential applications in the global market.
