6/ •
Be sure that the float specific gravity is at least 0.05 less than that of the measured
liquid as a safety margin at ambient temperature
•
For interface measurement: A minimum of 0.05 specific gravity differential is
required between the upper and lower liquids
•
When the magnet is not shown, the magnet is positioned at the center line of float
•
An offset weight is installed in the float to bias or tilt the float installed on the sensor
tube. So the float remains in contact with the sensor tube at all times and guarantees
permanent potential equalization of the float. The offset is required for installations
that must conform to hazardous location standards
