About This Manual:
PLEASE READ THE ENTIRE INSTRUCTION SHEET PRIOR TO
INSTALLING OR USING THIS PRODUCT. This Instruction sheet
includes information on all models of Vertical Mini-Floats from Omega:
LV-510 series. Please refer to the part number located on the sensor label
to verify the exact model which you have purchased.
User's Responsibility for Safety:
Omega manufactures a wide range of liquid level sensors and technolo-
gies. While each of these sensors is designed to operate in a wide variety
of applications, it is the user's responsibility to select a sensor 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.
Proper Installation and Handling:
Because this is an electrically operated device, only properly trained staff
should install and/or repair this product. Use a proper sealant with all instal-
lations. Never overtighten the sensor within the fitting, beyond being hand
tight. Always check for leaks prior to system startup.
Material Compatibility:
The LV-510 series is available in two different wetted materials. Models LV-
510 are made of Polypropylene (PP, a polyolefin). Models LV-511 are made
of Polyvinylodene Fluoride (PVDF). A Nylon C-ring is also used to secure
the float. Make sure that the model which you have selected is compatible
with the application liquids. To determine the chemical compatibility between
the sensor and its application liquids, refer to the Compass Corrosion Guide,
available from Compass Publications (phone 858-589-9636).
Wiring and Electrical:
The Vertical Mini-Float features a two-wire design with a SPST dry con-
tact closure. Electrical wiring of the sensor should be performed in accor-
dance with all applicable national, state, and local codes.
Normally Open/Normally Closed:
The orientation position of the float determines whether the switch is Open
or Closed. The top of the float has two concentric circles on each edge of the
cylinder. When the float is orientated up, the switch is open when the float is
away from the threads and is closed when the float is next to the threads.
When the float is orientated down, the switch is closed when the float is
away from the threads and is open when the float is next to the threads.
Flammable, Explosive and Hazardous Applications:
The LV-510 series should not be used within flammable or explosive applica-
tions. In hazardous applications, use redundant measurement and control points,
each having a different sensing technology. Refer to the National Electric Code
(NEC) for all applicable installation requirements in hazardous locations.
About Single Station Sensing
Omega's LV-510 series use a magnetic float which rides up and down a stem
containing the reed switch. The only moving part is the float. No bearings,
packing glands, bellows or electronic gadgets are used. The Vertical Mini-
Floats are built rugged to resist shock and vibration. The LV-510 series uti-
lize a low cost, flexible design which allows for vertical mounting at the top
or bottom of a tank. The Vertical Mini-Floats can be mounted up, down or
up to 20 degrees off vertical.
