NNT Water Flow Sensor Switch NPF3W Digital Water Flow Meters
The principle of the water flow switch is to measure the water flow. You can measure the pressure drop at both ends of the valve, orifice plate, and then check the pressure drop and flow curve of the valve or orifice plate to get the accurate flow, which can be obtained by the pressure drop method. Flow rate has been widely used in HVAC water side systems and flow measurement instruments. The application of the differential pressure switch in the HVAC system is mainly controlled according to the resistance and flow curve of the HVAC equipment, the water side heat exchanger in the HVAC (tube-in-tube type, shell-and-tube type, tube-plate type and commonly used plate heat exchanger) , Water filters, valves and pumps all have their pressure drop and flow performance curves. As long as the measured pressure difference on both sides of the pressure difference switch is compared with the preset value, the flow can be accurately controlled. The differential pressure switch is used as the flow control in HVAC with accurate flow control, no additional resistance to the water system, no requirement for the diameter of the water pipe, and no disturbance of water flow. It can replace any form of target flow switch. In the target type flow switch, it can avoid the false flow caused by the cavitation of the water pump, and has a very accurate reset flow and disconnect flow.
