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
