Product Description

NNT Automatic Flow Switch For Water Digital Water Flow Meters


There are many ways to detect the fluid flow state. Generally, water flow switches are roughly divided into three types. One is the early mechanical flow switch, also known as the baffle type flow switch. Its principle is to push the baffle through the flow of water. Deflection, and then touch the micro switch to move. The advantage of this kind of mechanical flow switch is that it is easy to use and cheap. The disadvantage is that the mechanical structure will be worn out, and the action is not very stable when the water quality is not good; one is the thermal flow switch, which is The principle is that the amount of liquid flowing is different, and the amount of heat taken away is different. By detecting the amount of heat loss, the flow of water can be detected. The advantage of this kind of water flow switch is that there are no moving parts and no wear and tear, which greatly enhances its life and stability. The disadvantage is that the price is slightly more expensive than the mechanical type; the last type is the differential pressure flow switch. The pioneering type of flow switch accurately controls the flow according to the curve of the pressure drop and the flow of the heat exchanger, and does not produce any pressure drop on the air conditioning system.
