By arranging the measuring channel to guide the water flow to the measuring channel for measurement, compared with the scheme of directly arranging the sensor 5 in the water inlet channel 221, the occupation of the measuring component of the sensor 5 to the inner space of the water inlet channel 221 can be avoided, so that the water inlet channel 221 generates flow loss.

It will be appreciated that in other embodiments, the sensor 5 is not limited to be a turbine flowmeter, but may be other types of flowmeters, and accordingly, the shape of the fourth conduit 25 and the connection manner of the fourth conduit 25 to the sensor 5 may be adjusted accordingly according to the type of the sensor 5, for example, when the sensor 5 is an electromagnetic flowmeter, the fourth conduit 25 may be configured to have one end connected to the valve body 21 and the other end connected to the side wall of the third conduit 24, two electrodes of the electromagnetic flowmeter passing through the wall of the fourth conduit 25 on opposite outer walls of the fourth conduit 25, and two electrodes of the electromagnetic flowmeter contacting the water flow when the water flow passes through the fourth conduit 25.
