We will encounter such a problem when we use the electric heating kettle to connect the purified water. Because the tap has a small amount of water and needs to be filled with water. In this case, we often choose to do other things. When we think of it, the water has overflowed for a long time and wasted a lot of water.
Measuring faucet arises from this. If we need to wait for water or want to arrange time as a whole, as long as we turn the switch on the disc to a certain scale, the flow of water to a fixed amount will automatically stop, which brings us some convenience in life, and also plays a role in saving water.
