Application fit for water and revenue metering
The Siemens 7ME6810-4HC31-1CA0 is a battery-operated electromagnetic flowmeter from the SITRANS FM MAG 8000 series, designed for volume flow measurement of conductive liquids and water in abstraction, distribution networks, revenue metering, and irrigation. The DN 150 (6-inch) flanged body mates to EN 1092-1 PN 16 pipework, and the EPDM liner handles potable water and general aqueous media up to the liner's temperature limits.
Accuracy and calibration traceability
Calibration is standard with certificate, achieving a maximum error of 0.4% of rate ± 2 mm/s — this is the accuracy floor for custody-transfer-adjacent metering, not just a full-scale spec. The Hastelloy electrodes resist corrosion in aggressive conductive liquids, and the corrosion-resistant coating (Category C4) protects the body in outdoor or humid environments.
Power, communication, and installation constraints
Powered by an internal battery (not included), this flowmeter operates without external mains — critical for remote abstraction points or distribution nodes where line power is absent. Communication is via a standard IrDA interface only; no additional protocol modules are fitted, so data retrieval requires line-of-sight infrared access. The basic remote version includes 10 m mounted sensor cables with plugs, simplifying installation when the transmitter is mounted away from the sensor.
The 7ME6810-4HC31-1CA0 is a Europe-region variant (EN flange, PED compliance), so confirm regional code compatibility for non-European installations.
