Multi jet water meter with dry dial register for residential utility metering DN15 Brass
General Description
The multi-jet meter operates on the velocity principle where water enters the measuring chamber through a number of ports and drives a rotor. The rotor velocity is proportional to the flow. Available in sizes 15mm to 40mm with nominal flow rates of Qn 1.5m3/h to Qn 10m3/h.
Product applications
The water meters are intended for the metering of cold potable water and hot water
