Tank Level Measurement using Manometer


#1

This article covers the Tank Level Measurement using Manometer and find out the tank level with u-tube manometer. Calculate Empty and Full range.

Tank Level Measurement using Manometer

The DP cell is replaced by a u-tube manometer using mercury (density 13600 kg/m3), with its zero level 1 meter below the bottom of the container, calculate the full and empty readings, hempty and hfull.

Empty:

Equating pressures on the XY line:

Patm+1000×(1+½h)×9.81 = Patm+13600×h×9.81

∴1 + ½h = 13.6h

∴hempty = 0.07634 m = 76.34 mm.

Full:

Equating pressures on the XY line:

Patm+1000×(6+½h)×9.81 = Patm+13600×h×9.81

∴6 + ½h = 13.6h

∴hfull = 0.458 m. = 458 mm.
