Water meter JS for cold water, type GSD8-RFM, DN15 (1/2"), Q3=2.5 m³/h, R160/50, Tmax: 50°C, L=110 mm, connection GZ3/4", dry-running, anti-magnetic, for remote reading 8MA00F12SSCMV0

Single-jet dry-running water meter with anti-magnetic protection and pulse transmitter compatibility

This is a dry-running single-jet water meter driven by a reinforced four-pole magnetic coupling that eliminates slippage and mechanical failure. The eight-drum counter rotates 360°, enabling easy reading from any angle. The impeller bearing uses a sapphire stone — enhancing sensitivity at low flow rates and extending the device’s service life.

The water meter is standard-equipped with anti-magnetic protection: a shield ring prevents interference from magnetic fields, safeguarding against measurement tampering. The design complies with Directive 2004/22/EC and is MID-approved, with accuracy classes R160-H (horizontal) and R50-V (vertical). The nominal flow rate is 2.5 m³/h, with a maximum of 3.125 m³/h.

Operation is strictly limited to water temperatures up to 50°C — clearly specified as Tmax: 50°C. No data confirms operation at higher temperatures for this version. The male thread connection GZ 3/4" is compatible with standard water supply systems. Overall length: 110 mm; weight: 0.5 kg — no additional mounting brackets required.

Nominal pressure: 16 bar. The meter is designed for installation of a radio pulse transmitter module (clip-on type), but such a module is not included in the standard delivery. This means a radio module can be added post-installation, but it is not part of the supplied product.

All wetted materials are certified for potable water measurement — confirmed by a Hygienic Certificate.
