DMG G4 Gas Meter
Analog / AMR / Angled Index
Digital / Digital(Leakage Detection)
Dual / BLE

 

 

 ■ General Information
Residential gas meters apply the diaphragm-type (positive displacement) metering principle to accurately measure gas consumption. They are used in a wide range of residential environments, including single-family homes, apartments, and multi-family dwellings, and are reliable products that satisfy KTC Type Approval and OIML international performance requirements.

 ■ Product Features
● Reliable product that meets KTC technical standards and has obtained NMi (Netherlands) OIML certification
● Diverse product lineup including Analog, AMR, Angled Index, Digital, Digital(Leakage Detection), Dual and BLE types
● Left and right type options available, supporting bidirectional piping installation
● Excellent low-flow performance relative to maximum flow rate, enabling accurate gas usage measurement
● Lightweight product design improves convenience in transport and installation
● Outstanding wear resistance, cold resistance, and temperature resistance ensure stable metering performance with long-term durability
