A differential pressure transmitter is configured to measure the height of an open tank : height 10m and dia 5m.
Suppose this same transmitter is shifted to another open tank : height 10m and dia 4m.
What will be the %error in measurement? how?

Zero error because of both tank height same

Answer / bala
Height of the tank from the ground affects the differential pressure calculations. P = h X d X unit area.
Since the area is constant. I thick I am correct. 1meter of water with density 1 is 10 kpa. Height is measured from ground level in meters.
So the pct of error is zero provided the tank is at ground level medium and location is same. The tank height and diameter formula to calculate the volume will change or affected

In split range control, we will control 2 outputs with time interval. Eg :(with 4-20 ma signal, for 4-12 ma we are operating one control instrument like valve & for 12-20ma we are operating other control instrumet (other valve). If we get a signal of 15ma to first instrument (Valve 1), what will happened to the first valve, and if we get signal above 20 ma to 2 valve what will happened ?
