Flow calculation through a valve

Flow calculation through a valve

Flow calculation through a valve

(OP)
HI,

How to calculate flow through a valve for gases and liquids. Valve already installed but no transmitter to indicate flow in pipe.

Thank you

RE: Flow calculation through a valve

Without a flow transmitter, you cannot accurately know the flow. However, one can calculate the flow using the control valve opening if the following information are available.
  • Inlet and outlet pressure
  • Details of pipe between the pressure measurement points and the control valve
  • original control valve calculation
  • control valve charecteristics
  • Fluid properties used in the original control valve calculation
This is not a simple calculation but if it is required regularly, it is possible to program the necessary calculation in the DCS / BPCS system.
