Water supply device for use as filling tap for hot water supply network in heating system, has electric control unit, where electric signals of conductivity- and flow rate measuring devices are coupled with each other in control unit
Water supply device for use as filling tap for hot water supply network in heating system, has electric control unit, where electric signals of conductivity- and flow rate measuring devices are coupled with each other in control unit
The device has a conductivity measuring device (14) i.e. conductometer, and a flow rate measuring device (15) i.e. fan-flow meter, comprising electric signal lines connected to an electric control unit, where electric signals of the conductivity- and flow rate measuring devices are coupled with each other in the control unit. The control unit is connected to a shut-off device (16) e.g. magnet valve and motor-driven gate valve, that blocks pipe cross-section of a water pipe (11). A sieve (17) is arranged in a region of an inlet (12) and/or an outlet (13) of the water pipe. An independent claim is also included for a method for monitoring water flow rate through a water pipe.
