What is a PT square root function(PT?) use in fucntion block diagram?
(OP)
What is the (PT√) function. It is my first time to do the functional block diagram for industrial plant related on instrument control. It very difficult fo me to understand the diagram. any related response will be appreciated, thanks... am newbie here...

I suspect the combination of measurements, flow rate, temperature, and pressure constitute a gas flow computer.
Gas flow rate from a flow rate meter is typically temperature and pressure compensated to achieve an inferred mass flow measurement.

So you mean my statement above is a flow meter compensated with pressure transmitter as a correction to get iferred mass flow rate. Actually the pressure trans. is installed in steamheader from boiler then theirs a pipe towards steam acummulator where the flow trans and control valve installed respectively. What is the typical or facts ratio of these FT and PT process variable(PV) to Output Manipulated Variable (MV) towards control valve. Thank you very much its getting more clearer to me.
