The CGR-04 M is here.
For over a decade, the CGR-04 M rotary gas meter has set the standard for reliability in mechanical gas metering. Now, that legacy has evolved into something even better – the CGR-04 M, the next generation of rotary gas meters designed to meet today’s commercial billing and industrial demands.
From great to extraordinary
The CGR-04 M retains the proven mechanical displacement principle that made its predecessor trusted worldwide, while adding features that make it more versatile, accurate, and future-ready:
Built to last – IP66/67 housing for tough conditions.
Global approvals – MID, ATEX, PED, and EMC certified.
Two installation positions – horizontal or vertical for maximum flexibility.
Maximum rangeability – up to 1:400 for precise measurement across varying loads.
Low pulsation performance – stable readings in high-demand environments.
Wide size range – G10 to G250, covering flows from 0.25 m³/h to 400 m³/h.
Where does it fit in?
The CGR-04 M rotary gas meter is engineered for:
Commercial gas billing where accuracy and compliance are critical.
Industrial gas measurement in manufacturing, processing, and utilities
Network upgrades replacing ageing meters with modern alternatives
Flexible installations where mounting options are limited
Key specifications
- Nominal diameter: DN40 to DN80
- Flow range: 0.25 m³/h to 400 m³/h
- Working pressure: up to 1.6 MPa (MID)
- Temperature range: –25°C to +70°C
- Accuracy class: OIML-R137, class 1
