RMG - Model ERZ 2000-NG -Flow Computer
The instruments of the ERZ 2000-NG series are designed as universal instruments that can be used for all measurement tasks in a gas measuring station. RMG has optimised the ERZ system with regard to operability and user-friendliness. This makes it even more efficient in operation and provides more precise results.
