Description:
The Sensus MeiStream FS flow sensor is a high-precision device designed for heat and cooling metering applications. Built on the proven reliability of the Woltman WP and WS meters, it combines high measurement accuracy with excellent performance across both high and low flow ranges. Suitable for water temperatures up to 90 °C (heat) and from 5 °C (cooling), it is approved under MID MI004 / EN 1434, accuracy class 2. The innovative impeller with a spherical hub provides friction-free operation at higher flows, ensuring long service life and stable performance. Thanks to its three-dimensional hydrodynamic balance, the MeiStream FS can be installed in both horizontal and vertical pipe configurations, offering exceptional flexibility.
