Cautions
FLOWLINE manufactures a wide range of liquid level switches and technologies. While each of these switches
are designed to operate in a wide variety of applications, it is the user's responsibility to select a switch model
that is appropriate for the application, install it properly, perform tests of the installed system, and maintain
all components. The failure to do so could result in property damage or serious injury.
1. The pressure, temperature and electrical limitations shown for the specified level switches 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 switch varies with applications.
5. Ambient temperature changes can affect switch set points, since specific gravities of liquids vary with
temperature.
6. Level switches have been designed to be shock and vibration resistant. For maximum life, both shock
and vibration should be minimized.
7. Excessive contaminants in fluid may inhibit float operation, and occasional wipe down may be
necessary.
8. Level switches must not be field repaired.
9. Physical damage to product may render product unserviceable.
10. Installation in a vessel made from magnetic materials may affect operation.
