Answer Posted / valluri066
Range is Negative mmWC to Zero because we are using "Wet leg configuration" arrangement. In which LP side of transmitter is contains a Condesate Pot always filled-in with water.
Wet leg configuration is used when the tanks contain CONDENSABLE VAPOURS, these vapours when entered impulse lines may be condensed over time and get accumulated. This accumulated liquids in impulse line creates Pressure head resulting error in level measurement. to avoid this suituation we initially fill LP side impulse line with water ( or a condensate pot is used to condense vapour and fill impulse line automatically).
