WATER FLOW SENSOR
APPLICATION
The sensor is primarily designed to measure the Domestic
Hot Water (DHW) flow rate in domestic appliances as follows:
Combi boiler
Instanteneous Water Heater (IHW)
Other systems such as applications where the
instanteneous DHW is produced from district heat
input.

Page 2: Description
DESCRIPTION The C7195A is a mechanical water flow sensor (fig. 2.). Electronic A turbine rotates with water flow. The turbine supports a Controller magnet which rotates in front of a Hall effect sensor. This Hall effect sensor picks up the field of the magnet giving a pulsed output.The output is directly proportional to the water... -
