The smart flow and flow resistance detection center consists of stainless steel water tank, pressure supply system, pressure stabilization system, test pipeline, data sensing acquisition system, data processing system, control system, etc.
Detection principle: The control system outputs signals to the control valve according to the preset program of the system. After the control valve runs to a certain opening position, the flow meter detects the actual flow rate and records and collects it, and finally draws the flow characteristic curve;
This device simultaneously solves the problems of siphon and pressure fluctuation interference behind the valve of current domestic flow resistance testing devices, with good stabilizing effect, improved accuracy and traceability of test results, and added position accuracy testing function for regulating valves. One click automatic testing can significantly reduce manual operation intensity and achieve high accuracy.
