Zero Elevation:
An elevated zero is needed for a gage or absolute transmitter mounted above the high side tap ( The Bottom Process connection ) or for a two seal differential pressure application.In these causes ,the transmitter reads a negative pressure . When the tank is empty due to the head pressure effectof the capillary fill fluid
Zero Elevation
A Suppressed zero is needed when a gage or absolute pressure transmitter is mounted below the high side up tap ( the bottom process connection).When the transmitter is mounted the high side tap,the fill fluid in the capillary puts pressure on the transmitter sensor causing it to give a positive pressure reading even when the tank is empty.

The company where I am working, their is rosemount 5400 series radar type level transmitter, it is meant to show level of filled tank, but along with the level it is showing temperature also, so my question is how a onon-contact type radar type level transmitter can show temperature even if it does not have any contact with the fluid?
