Find out what the MWN / JS-S; -NKP water meter has to offer

The MWN / JS-S; -NKP is a high-end coupled water meter designed for precise measurement of water consumption at temperatures up to 50°C, under conditions of highly variable flow rates. The installation is performed in horizontal pipes with the display facing upwards and it comes as standard with an IP65-rated display. The water meter is designed for use in remote reading systems. By using the MWN, you gain:

Capable of operating at a working pressure of up to 16 bar

Protection of the mechanism against malfunction by locking the rotation of the counting mechanism at an angle greater than 358°

Option of optical or inductive reading of the display

Precise measurement even at very low flow rates

Stable and accurate measurement thanks to the application of double-sided bearing rotors
