Single Jet Water Meter (D3-5+4)

NWM SJ-SDCD3 is IMPELLER (turbine) water meter with magnetic transmission, dry type register for residential application with sizes from Dn15 to Dn40designedand manufacture by NWM and meets to the requirements of Directive 2004/22/EC on measuring instruments; The European Standard EN14154+A1+A2: Water Meter; The International Organization of Legal Metrology OIML R-49: 2006(E): Water meters intended for the metering of cold potable water and hot water. Or comply with ISO4064 standard

Characteristics:

All the Materials in contact with water, consciously selected by the known resistance to corrosion;

Cold water meter under current standard for lower than 30ºC(T30), but NWM SJ-SDC D3 can be used safely in water temperature up to 50ºC(T50);

Hot water meter under current standard for Lower than 90ºC(T90);

The ROTARY indicator register for the most comfortable reading position is of 8 Rollers and 1 Pointer;

The Impeller is the only moving parts in contact with water permitting the most reliable;
