Hydrostatic tank shell correction (HyTD)

The hydrostatic tank shell correction can be used to compensate for vertical movement of the Gauge

Reference Height due to bulging of the tank shell caused by the hydrostatic pressure exerted by the

liquid stored in the tank. The compensation is based on a linear approximation obtained from

manual hand dips at several levels distributed over the full range of the tank.

Thermal tank shell correction (CTSh)

The thermal tank shell correction can be used to compensate for vertical movement of the Gauge

Reference Height due to temperature effects on the tank shell or stilling well. The calculation is

based on the thermal expansion coefficients of steel and on insulation factors for both the dry and

wetted part of the tank shell.

This correction is recommended for any tank gauge operating at conditions deviating

considerably from the conditions during calibration and for extremely high tanks. For

refrigerated, cryogenic and heated applications this correction is highly recommended.
