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 Flowline:
LV20-_2_1. 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:
Flowline manufactures a wide range of liquid level sensors and technologies. 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 installations. Never overtighten the sensor within the fitting, beyond being hand
tight. Always check for leaks prior to system startup.
Material Compatibility:
The L V20 series is available in two different wetted materials. Models LV2012_1 are made of Polypropylene (PP, a polyolefin). Models LV20-52_1 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 619-589-9636).
Wiring and Electrical:
The Vertical Mini-Float features a two-wire design with a SPST dry contact closure. Electrical wiring of the sensor should be performed in accordance 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 LV20 series should not be used within flammable or explosive applications. 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
Flowline's L V20 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 MiniFloats are built rugged to resist shock and vibration. The LV20 series utilize
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.
