The Importance of the Liquids S.G (Specified Gravity)
Submersible Pressure Sensore are designed to be completely submersed
within the liquid. The transmitters can rest along the bottom of the tank or
be suspended at any desired level within the tank.
The S.G of a Liquid has a Direct Effect on the Sensors Output when Measuring
the Height of the Liquid
Liquids with a S.G < 1.0 are Lighter than H

O i.e. Oil
Liquids with a S.G > 1.0 are Heavier than H

O i.e. Sulfuric Acid
S.G < 1.0 Requires More Liquid to Equal the Same Pressure or Height as with H

S.G > 1.0 Requires Less Liquid to Equal the Same Pressure or Height as with H

O has a SG = 1.0
Here are some examples of how the submersible sensor range changes when
submersed into liquids with different Specific Gravities
Please note that the physical location of the level transmitter will indicate
the lowest level of measurement within the tank.
ex : Positioning the transmitter 12" from the bottom of the tank, then the
lowest reading of liquid will be 12" from the bottom.
When the Liquid To Be Measured is Not H

O the New Range of the Sensor
Needs to be Determined.
To Achieve this Simply Divide the Range of the Sensor Body by the Specific
Gravity of the Liquid
SENSOR RANGE / S.G = NEW RANGE
