  • Page 19: Function

    1 ABOUT THIS MANUAL 1.3 Function The flow computer ERZ2000-DI is designed to operate various sensors, particu- larly flow rate and gas analysis sensors, evaluate their signals or adopt and deter- mine resulting operating and nominal volume flows. The resulting calculation varia- bles can be represented in a graph and checked via alarm output, etc.

  • Page 20: Overview

    1 ABOUT THIS MANUAL The ERZ2000-DI records analogue and digital values, such as frequencies, re- sistances, etc. Then these are assigned to physical variables, such as operating volume flow or temperature. Further processing of these values takes place in the ERZ2000-DI, where, for example, gas characteristics and standard volume flow are calculated from these basic values.

  • Page 21: Areas Of Application

    1 ABOUT THIS MANUAL 1.5 Areas of application The essential area of application is the recording and metering of flow rates for custody transfer in natural gas flow measurement technology. The device can be delivered in two different versions of the software, each with a separate approval as: Status flow computer for natural gas (ERZ2004-DI) Calorific value flow computer for natural gas (ERZ2104-DI)
  • Page 22 1 ABOUT THIS MANUAL Danger Only use the ERZ2000-DI in its original condition. When connecting sensors and other devices in explosion-prone areas, ensure that the appropriate explosion protection is provided for these components. The specified maximum values in the certificates issued for these components must be observed.
