Elster® enCore ZM1 Flow Computers
Overview
The Honeywell Elster enCore ZM1 is a flow computer of the latest generation, engineered for accurate gas volume measurement, flow calculation, and data registration in custody transfer and distribution metering applications. Its modular process card system enables flexible configuration and future-proof expandability as metering requirements evolve.
In addition to the common k-number calculation methods, the ZM1 implements functions in accordance with DVGW worksheet G 485 and supports the DSfG protocol, the established digital interface for gas measuring devices in European and international gas networks. The integrated registration stores interval and event-oriented measured values, meter readings, and alarm records, forming a real-time load profile for billing and network analysis.
Engineering & Design
The enCore ZM1 is built around a modular architecture where process interface cards handle different input types, allowing the device to be adapted to the specific metering station configuration. This modularity simplifies maintenance, reduces spare part complexity, and allows the flow computer to grow with the station without replacement of the complete unit.
Data communication via DSfG is integrated as standard, and the device can transmit registered data wirelessly using GPRS or GSM through UMM cellular routers. The registration database is designed for long-term storage of interval and event records, supporting both online retrieval and local archiving for verification and audit purposes.
