The UG4-AL is a high-pressure diaphragm gas meter designed for commercial and LPG applications. Its robust aluminium housing ensures accuracy and stability for over 15 years of operation. With a maximum working pressure of 2 bar (tested to 3 bar), it performs reliably under higher line pressures than standard diaphragm meters.
The flow range spans from 0.04 (optional 0.016) – 6 m³/h, with a starting flow as low as 0.006 m³/h, providing precise readings even at low flows. Its patented tamper-proof counter, anti-backflow safety system, and magnetic transmission ensure operational security. The meter supports retrofitting with pulse transmitters and remote reading modules for GSM/GPRS or RF smart metering systems.
- CE-MID Approved and Marked
- EN 1359 – European diaphragm meter standard
- Tested up to 3 bar (aluminium body)
