SEN-HZ21FB Liquid flow sensor, we have two series ,G1/2 extenal teeth and bayonet(23mm). Can be changed the structure, G3/4 special teeth into the water and the extanal teeth of the G1/2 out the water.Size: 30*66 mm, Waterproof explosion-proof, heat and cold resistance. the pulse signal output,can be used for water flow switch, also can be used to measure flow rate at the same time,have two flow range.If you want to increase the temperature control ,you can add heat sensitive resistor, the output line is green, but also can be connected to the other two special line to control temperature.
