The
temperature transmitter has an integrated water level sensor attached
to the temperature sensor tube to measure free water level at the bottom
of the tank. It enables correct product volume calculations.

The
 multiple spot temperature sensors measure temperature with a number of
Pt-100 spot elements placed at different heights to provide a tank
temperature profile and an average temperature.

Only
fully immersed elements are used to determine product temperature. One
of the temperature sensor elements may be installed inside the water
level probe.
