How does the pressure sensor control the flow of the pump?
The pressure sensor provides pressure information feedback to control the pump pressure and can not control the flow directly
He is not a pressure sensor to control the pump flow. And adjusting device, control device combination, to control the pump flow. Such as: pressure sensor pressure signal will be output to the PID regulator, PID regulator will compare the pressure signal and the output signal is given, and then control the opening of the regulating valve, or control of frequency converter the frequency, so you can control the flow of pump.
The pressure sensor can not control the flow rate of the pump, the pressure sensor is only the transmission of the pressure information to the control center, the control center of the output signal to control actuator to do transformation invariant in other parameters, pressure and flow in a relationship, the specific reference to Bernoulli equation:The Bernoulli principle is often expressed as p+1/2 P v2+, P gh=C, this formula called the Bernoulli equation. Where p is the pressure of a point in the fluid, the fluid velocity of the V point, - fluid density, G for the acceleration of gravity, to the point where the height of H, C is a constant. It can also be expressed as p1+1/2 P P gh1=p2+1/2 v12+ P v22+ GH2 P.
