SDMQ – Smart Diaphragm Gas Meter
Versions
SDMQ - SMART GAS METER G4 1” 1/4 110mm DIAPHRAGM / VALVE - STEEL BODY
SDMQ - SMART GAS METER G4 1” 1/4 110mm DIAPHRAGM / VALVE - ALUMINIUM BODY
SDMQ-G4 is designed and manufactured to measure the volume of Natural Gas and Liquefied Petroleum Gas (LPG).
The measurement technology is based on a traditional diaphragm meter, which also integrates a temperature sensor for volume conversion and permits achieving high accuracy and performance.
The Smart Gas Meter satisfy the new generation of smart devices to fulfill all requirements of European and International standards MID-OIML.
The type of gas and any impurity do not interfere with the performance of this device, mainly used in low-pressure gas distribution networks for residential natural gas and LPG.
Fully compliant for Hydrogen NG-H2 blending.
