Calculate the liquid level in the tank


#1

A DP transmitter, correctly calibrated to measure the level of a liquid in a 5 meter high open container, delivers an output pressure of 50 kPa. Calculate the liquid level in the tank.

DP%20transmitter%2C%20correctly%20calibrated

Answer :

Liquid level H = [(50-20)/(100-20)]×5 = 1.875 m.

Or alternatively: 50 = 16×H + 20 ⇒ H = 1.875 m
