Level compensations directly affect the accuracy of the level
measurement.
Description
Compensates for the slip between inner and outer magnet.
This compensation should be enabled when the gauge measures at
different interfaces or when the ambient temperature change exceeds
10°C (18°F).
This compensation must be enabled for W&M approved applications!
Compensates for the changes in slip between inner and outer
magnet due to temperature.
This compensation should be enabled when the ambient temperature
change exceeds 10°C (18°F). If this compensation is enabled, the
'Magnetic coupling' compensation also needs to be enabled.
This compensation must be enabled for W&M approved applications!
Compensates for the thermal expansion of the measuring wire.
Enabling this compensation is highly recommended when the vapour
temperature is available (VITO).
This compensation needs a valid vapour temperature (VITO).
This compensation must be enabled for W&M approved applications!
Compensates for the expansion of the wire because of the weight
attached to the wire.
This compensation should be enabled when the gauge measures at
a different interface than the air-product interface or when the set
point of the air-product interface is different from the default 0.208 kg.
Compensates for the expansion of the wire because of the weight
attached to the wire for the part of the wire that's wound on the drum.
This compensation should be enabled when the gauge also
measures density or measures at various interfaces (e.g. performs
water dips).
Compensates for the thermal expansion of the tank shell. Enabling
this compensation is recommended for tanks higher than 20m. When
this compensation is enabled, the 'Wire temperature' compensation
must also be enabled.
This compensation needs a valid vapour and product temperature
(VITO).
Compensates for the hydrostatic deformation of the storage tank.
Compensates for snow on the floating roof.
Compensates for the thermal expansion of the drum.
Enabling this compensation is highly recommended.
This compensation must be enabled for W&M approved applications!
