P600 submersible static pressure liquid level gauge adopts advanced circuit processing and temperature compensation technology to convert the liquid level measurement value into a standard DC signal output of 4~20mA. The product has strong anti-interference ability, small temperature drift, high stability, high measurement accuracy and tightness. According to different measuring media, ordinary type or anti-corrosion type can be selected.

Applicable environment
■ Level measurement in containers and storage systems
■ Sewage and flood drainage system monitoring
■ Water level monitoring of ship ballast water tank
■ Water level measurement of rivers and lakes
■ Deep well and groundwater monitoring
■ Water level monitoring of factory pools

Working principle
The pressure that the sensor is put into the liquid is calculated as P=ρgh+P0
P: The pressure on the sensor at the point to be measured
ρ: medium density
g: local gravity acceleration
h: the height of the measured point from the liquid surface
P0: Atmospheric pressure on liquid level
