Flow switch

Flow switches simply provide switch or ON / OFF output at the set point or set point with various mechanisms for sensing fluid flow, and allow you to control the line flow. Usually, the simplest methods are the most widely used, and in very common flow switches, they use a metal blade that is attached to a lever, cut the length of this blade, or so-called trim, according to the set point. When the flow reaches your set value, the lever is tilted to one side and the switch is actuated. In more advanced examples, this switch is used non-contact, for example with the help of the magnetic property of the end of the lever, which stimulates the output relay reed. In choosing this equipment, the following should be considered

1. Range fo flow switch
2. contact way
3. Connection type
4. Fluid density or viscosity
