NWM SJ-SDC (D3) is IMPELLER (turbine) single jet water meter with dry type register for residential application with sizes from Dn15 to Dn40 designed by NWM and meets to the requirements of Directive 2004/22/EC on measuring instruments and of European Standard EN14154 and International Organization of Legal Metrology OIML R49.
The single jet cold water meters can be added with a remote transmission function and centrally managed by collecting data through electromechanical conversion of non-magnetic counting functions and transferring data via NB-loT / LoRa /LoRaWAN/Wireless MBus network.
The measuring mechanism and the counting mechanism of the impeller are driven by magnetic coupling, and the character wheels and pointers are displayed in combination. The single jet cold water meter has characteristics of convenient reading, long-term clear surface, anti-freezing, long service life, etc.
● All the Materials in contact with water, consciously selected by the known resistance to corrosion;
● Efficient production and simple structure to save cost for domestic water meter;
● High sensitivity to achieve accurate measurement of flow;
● Double display of pointer and roller for easy reading;
● Simple structure to reduce pressure loss;
● Reserve remote transmission function to realize data transmission;
● The most reliable composite material for the body to ensure strongest and the longest life;
● The Impeller is the only moving parts in contact with water permitting the most reliable;
● The conception of the Magnetic Protection to against the external influences;
● External calibration for easy operation.
