In open loop the varialble is for monitoring purpose e.g.
if we are using a pressure transmitter of pressure
indication only then the connection will be said to be open
loop whereas in closed lood the varialble is measured and
controlled also e.g. if we are using the pressure
transmitter as well as a control valve to maintain the
pressure in the tank then the connections will be said to
be in closed loop
