UGM-G6 / TGM-G6 Gas Smart Meter Series

The UGM-G6 Smart Meter Gas is designed and manufactured to measure the volume of Natural Gas and Liquefied Petroleum Gas (LPG). The measurement technology is based on an innovative ultrasonic sensor which integrates also the temperature sensor for volume conversion and permits to obtain an high precision and performance. The gas meters satisfy the new generation of smart devices to fulfill all requirements of European and International standard MID-OIML. Quality guarantee Made in Italy.
