10 954 Density option
10.1 Introduction
Functional description
A special software package for density measurement is available for the
954 SmartServo FlexLine gauge. This optional package offers the
possibility to measure tank density profiles and interface density
profiles.
Tank Profile density measurement offers the possibility to measure the
density at up to fifty spots in the product. The individual measurement
locations are equally divided over the complete product height.
Interface Profile density measurement offers the possibility to access
the density stratification at or around a specific interface-layer.
Tank profile density measurement offers high absolute density
accuracy, while Interface Profile measurement offers high position
accuracy.
In principle, tank profile density measurement realises the high absolute
density accuracy by measuring over a complete drum rotation to
minimize the influence of the unbalance of the drum. The measurement
offers the possibility though to measure only at one drum position. By
enabling the unbalance compensation, the measurement time can be
reduced while maintaining a high absolute density accuracy.
Interface profile density measurement always measures on only one
drum position. The accuracy of the density measurement can be
increased by enabling the unbalance compensation.
After completion of a density profile measurement an average density is
calculated.
Notes:
Application of servo density measurement is restricted to 'clean', non-
viscous products.
Absolute inaccuracies of less than 5 kg/m
3
(0.31 lbs/ft
3
) for the Tank
Profile density measurement, and
10 kg/m
3
(0.62 lbs/ft
3
) for the Interface Profile measurement can be
accomplished if the gauge is properly installed, calibrated and
maintained.
