Water Level Pressure Sensor
Submerged pressure sensor for water level measurement
This is a 4-20mA output pressure submerged sensor (dropped into tanks or bores to provide a measure of the level or depth of water). This hydrostatic level sensing probe has piezoresistive measuring elements that have compensated, adjusted and amplified sensor signals which are available as a standard 4-20mA output. It is especially suited for level measurement, even in the presence of corrosive liquids. Manufactured from stainless steel, its welded construction provides a watertight seal.
Note: if the upper atmospheric pressure changes, the pressure sensor will be affected by the same level of change as the liquid level
