Hydrant service equipment


Portable water meter PWM25

PWM 25 is a screw meter with horizontal rotor axis, which is coupled with a pressure gauge. The device's process connections are Storz 52 connectors. The basis of the PWM 25 measurement is a moving element in the form of a turbine rotor set in motion directly by the speed of the flowing water. The number of revolutions is measured by the device's electronics. The amount of water that has flowed through the counter is displayed on the screen. It is designed to measure the flow volume of contamination-free cold water.
