The ERZ 2000-DI presents itself as a cost-conscious solution without having to forego the usual reliability of RMG flow computers for volume conversion. A slim and user-friendly volume corrector is required in stations with few measuring rails and at exit points.
User-friendly volume corrector especially for the needs of distribution network operators
Intuitive configuration and operating software, usable with Internet browser, local and remote
Simple commissioning with an interactive wizard, the intelligent configuration wizard for the ERZ 2000-DI
Standardised DSfG Instance-F for simple data communication with ultrasonic meters
Signed data retrieval via Modbus and DSfG class B
K-number calculation also with latest equations of state according to AGA8 DC (2016), GERG 2008 and GERG 2004
Use in custody transfer or operational metering applications in combination with different types of gas meters:
Turbine meter
Ultrasonic meter
Vortex meter
Rotary piston meter
