General Information

1. Continuous Level Sensors
should be installed rigidly
so the float is free to move
as the liquid level changes.
2. Continuous Level Sensors
should be mounted in a tank
area free of severe turbulence
or protected from such
turbulence by appropriate and
adequate slosh shields.
3. Continuous Level Sensors
stems should be vertical for
best results, but satisfactory
operation is possible in most
liquids with the stem at up to a
30˚ angle from vertical.
4. Care should be taken that
Continuous Level Sensors are
always operated within
electrical ratings.

Cautions
1. The pressure, temperature and electrical limitations
shown for the specified level sensor must not be exceeded.
2. The pressures and temperatures must take into
consideration possible surges in the temperature
and pressure of the system.
3. The liquids used must be compatible with the materials
of construction. Specifications of materials will be given
upon request.
4. Life expectancy of the sensor varies with applications.
5. Ambient temperature changes can affect sensor set points,
since specific gravities of liquids vary with temperature.
Consult factory for assistance.
6. Level sensors have been designed to be shock and
vibration resistant. For maximum life, both should be
minimized. Consult factory for assistance.
7. Excessive contaminants in fluid may inhibit float operation
and occasional wipe down may be necessary.
8. Physical damage to product may render product unserviceable.
9. Installation in a vessel made from magnetic materials may
affect operation.
