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.
