ENIMEX DIAPHRAGM GAS METER G4
 Application
The ENIMEX Diaphragm Domestic Gas Meter Class G4 is a compact residential meter designed to measure accurately volumes of Natural Gas in apartments and households.
Basic Features
- Compact
- Light weight
- High metrological performance
- 100% corrosion proof
- Fire Safe Steel Casing
The have synthetic diaphragm, which is made of the best quality synthetic materials, with high dimensional stability, excellent chemical resistance, against effects of measured gases, and long term durability. Other important characteristics of the meters are the low operating noise level, the high measuring accuracy the low pressure loss.
The basic model is predisposed for external pulse emitter. The other options are the installation of low frequency pulse emitter, the AMR (remote Automatic Reading System) and the data management.
The fine error curve adjustments, controls and tests are made in our special designed Calibration Area.
