You can calibrate flow measurement devices by three methods: 1) wet calibration using actual fluid flow; 2) measurement check of physical dimensions and use of empirical gables relating flow rate to these dimensions; or 3) dry calibration using flow simulation by electronic or mechanical means.

how do i tune dearator pr control valve using PID. we set the set point is 0.6kg/cm2 now i want 0.5 to 0.7kg/cm2 limits so what should i give p,i,d values. then pls explain how do set pid values for control valve tuning?
