close the both hp and lp iso valve(so that any pressure
should not act on tx diaphragm). now measure the input
pressure in mm by connecting hand communicator to tx.. this
is the LRV.now measure span(ie here it is 850mm).multiply
span with liquid density(ie 850*0.73).we will get 620.5.
this is your URV
