ICON Levelpro 300S Series, Operating Manual, Page: 15 / 19

Lets assume a the calibrated range of the submersible sensor is 34" or 408. The range is always referenced H
2
O which has a specific
gravity S.G or (Density) equal to 1
Calibrated Range/S.G = Liquid Level Measurement Range 34/1 = 34' or 408/1 = Liquid Level Range = 408"
The liquid in Tank # 1 has a S.G = 0.5 which is Lighter thank that of H
2
0
To determine the New Range of the sensor simply divide the H
2
0 Range (34') by the S.G of the liquid that is going to be in the tank. S.G = 0.5
34/.5 = 64 feet or 816 inches
Since the oil is a lighter fluid than H
2
0 the new measuring range of the sensor has increased and is now 64' or 816"
The liquid in Tank # 2 has a S.G. = 2 which is 2X Heavier than H
2
0
The 34' sensor is now going to be installed into a tank to measure a liquid with a S.G = 2
Range / S.G = New Range of the Sensor
34/2 = 17.5 feet or 204"
