High-accuracy R50 and R200 configurations

Non-magnetic sensing resistant to interference and tampering

Multi-segment calibration and historical consumption records

Low-voltage alarm and high-contrast LCD

Epoxy-encapsulated electronics for wet chambers

Up to 1,200 metres communication distance

The WS Series is an intelligent wired remote-reading bulk water meter designed for accurate measurement, dependable data transmission and long-term operation in commercial, municipal and industrial water networks.

Reliable remote monitoring

Non-magnetic signal acquisition resists external magnetic interference and tampering. Multi-segment calibration, scheduled consumption snapshots and stored historical records support efficient utility monitoring and network management. M-Bus and RS-485 options provide communication over distances up to 1,200 metres.

Designed for demanding installations

The meter is available in R50 and R200 configurations for DN40 to DN200 pipework. A high-contrast LCD, low-voltage alarm and epoxy-encapsulated electronics provide clear local readings and dependable service in wet meter chambers. Horizontal and vertical installation are supported.

Metrological parameters

Flow values are stated in m³/h. Qm is minimum flow, Qt transitional flow, Qp permanent flow and Qs overload flow. R is the Qp/Qm measuring-range ratio.
