TANK LEAK SENSOR

MODEL LS-30

The sensor position is dependent upon the product level. If
the tank is 3/4 full the sensor should be submerged 3/4 of its
range. If the tank is 1/4 full the sensor should be submerged
1/4 of its range. The interstice liquid should always be below
the reservoir riser.
