MeiStream® FS Flow Sensor 90 °C


The MeiStream® FS Flow Sensor 90 °C combines the high reliability and measurement accuracy of the Woltman WP meter with the advantages of the Woltman WS meter in the lower measuring range. This combination creates an excellent flow sensor with an MID approval according to MI004 or EN 1434 in the accuracy class 2.

Volume pulses are generated by the interface HRI-Mei FS. This interface transfers volume pulses with programmable pulse values to the heating or cooling calculator. Possible reverse flows are compensated.
