Answer Posted / senthil.doosan
example for open loop - u can only monitor the output of
the transmitter(pressure,flow,temp.level)
example for closed loop-u can monitor the output of the
transmitter (pressure,flow,temp.level) and u can control
the process by using these parameters feedback by final
control element.
