Technology
The vertical buoyancy switch and the vertical float switch both consist of a float, magnet, reed switch and baffle body which dampens
turbulence and eliminates the negative effects of switch chatter. When
the probe is dry, the float rests on the bottom of the baffle body such
that the magnet does not influence the reed switch. As the probe
becomes immersed in liquid, the float becomes buoyant and the magnet elevates causing the reed switch to change state.

About this Manual:
Through Wall Installation:
PLEASE READ THE ENTIRE MANUAL PRIOR TO
INSTALLING OR USING THIS PRODUCT. This manual
includes information on the vertical buoyancy, model LV10-_3_1,
and vertical float switch, model LV10-_2_1. Please refer to the part
number located on the sensor label to verify the exact model which
you have purchased.
FLOWLINE’s LV10 switch may be installed through the top wall of
a tank. The sensor has male 3/4" NPT threads and a 3/4" bayonet
adapter on the LV10-_3_1. This enables the user to mount the LV10
using either FLOWLINE's Smart Trak™ or FLOWLINE's Switch
Pak™.
User's Responsibility for Safety:
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.
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 a maximum of 80 inch-pounds torque. Always
check for leaks prior to system start-up.

Material Compatibility:
The LV10 level switch is available in two wetted material versions.
The switch and cable are made of Polypropylene (PP) for the
LV10-1__1. The switch is made of Polyvinylidene Fluoride
(PVDF) and cable is made of Perfluoroalkoxy (PFA) for the LV105__1. Make sure that the switch 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 (858-589-9636).
Temperature and Pressure:
Low Level Sensor
Model LV10-_3_1
Note: Avoid installing the LV10 in magnetized metal
tanks. Doing so will activate the internal reed switch.
The LV10 series switch is designed for use in application temperatures up to 80 °C, and for use at pressures up to 25 psi (2 bar) @ 25
°C., derated @ 1.667 psi (.113 bar) per °C. above 25 °C.
Wiring and Electrical:
The supply voltage used for the LV10 switch should never exceed
120 volts AC @ 15 VA for the LV10-_3_1 and 120 volts AC @ 50
VA for the LV10-_2_1. For the CE versions, the supply voltage for
the LV10 switch should never exceed 30 Vrms and 42.4 Vpeak or
60 VDC. Electrical wiring of the switch should be performed in
accordance with all applicable national, state, and local codes.
Flammable, Explosive and Hazardous Applications:
The LV10 series switch should not be used within flammable or
explosive applications unless properly connected to a approved
control device. In hazardous applications, use redundant measurement and control points, each having a different sensing technology. Refer to the National Electrical Code (NEC) for all applicable
installation requirements in hazardous locations.
WARNING
Please observe the difference in wiring and operation between
the LV10-_3_1 and the LV10-_2_1.
Avoid installing the LV10 in tanks in magnetized metal tanks.
Doing so will activate the internal reed switch.

Orientation:
Voltage:
Mounting orientation must be kept vertical for proper operation. The
vertical buoyancy and float switches are orientated in the vertical
position ±20°.
The input voltage to the LV10 switch should never exceed the maximum voltage rating. FLOWLINE controllers have a built-in 13.5
VDC power supply which provides power to all of FLOWLINE’s
level switches. Alternative controllers and power supplies may also be
used with the LV10 switch.

Cable Length:
Determine the length of cable required between the LV10 series sensor and its point of termination. Allow enough slack to ensure the easy
installation, removal and/or maintenance of the sensor. The cable
length may be extended up to a maximum of 1000 feet, using a wellinsulated, 18 gauge shielded wire.
Wire Stripping:
Using a 10 gauge wire stripper, carefully remove the outer layer of
insulation from the last 1-1/4" of the sensor's cable. Unwrap and discard the exposed foil shield from around the signal wires, leaving the
drain wire attached if desired. With a 20 gauge wire stripper, remove
the last 1/4" of the colored insulation from the signal wires.

Removing Baffle (LV10-_2_1 Only):
Float
3/4 NPT
The vertical float, model LV10-_2_1, can be installed with out the
protective shield. To do so, remove the shield by twisting it off from
the bayonet adapter. Make sure the C-clip is added to the post to prevent the float from falling off.

Output Selection (LV10-_2_1 Only):
The selection of normally open or normally closed for the
LV10-_2_1 is made by the orientation of the float. The
switch arrives from the factory in the NO position (open circuit when dry). The top of the float is identified by the rough
edges at the end of the float. The smooth end is the bottom
of the float. To change to NC, rotate the float 180°.

Normally Closed:
Use the Black and Red wires for operating the LV10-_3_1 in a normally closed state. Normally closed is defined as the switch being

Vertical Float Level Switch (LV10-_2_1):
General:
The LV10-_2_1 switch can be wired normally open or normally
closed for your application requirement.
While a filter shroud protects the float from particulate contamination, the switch may need to be cleaned periodically too prevent jamming or sticking. The vertical buoyancy and vertical float has no
scheduled maintenance requirement, except to clean off any deposits
or scaling from the switch as necessary. It is the responsibility of the
user to determine the appropriate maintenance schedule, based on the
specific characteristics of the application liquid.
Normally Open:
Only use the Black and Red wires with the LV10-_2_1. Orientate the
float upward so that the switch is in the normally open state. Normally
open is defined as the switch being open when the float is dry and
closed when the float becomes submersed. This operation is typical
for indicating a high level.

Normally Closed:
Only use the Black and Red wires with the LV10-_2_1. Orientate the
float downward so that the switch is in the normally closed state.
Normally closed is defined as the switch being closed when the float
is dry and open when the float becomes submersed. This operation is
typical for indicating a low level.
Cleaning procedure:
1. Power: Make sure that all power to the switch, controller and/or
power supply is completely disconnected.
2. Switch removal: If necessary, make sure that the tank is drained
well below the switch prior to removal. Carefully, remove the sensor from the installation. Remove the outer screen by pushing on
the screen and turning is slightly to disconnect is from the bayonet connector so that the float is exposed.
3. Cleaning the switch: Using a soft bristle brush and mild detergent, carefully wash the switch. Do not use harsh abrasives such
as steel wool or sandpaper, which might damage the surface of the
sensor. Do not use incompatible solvents which may damage the
sensor's PP or PVDF plastic body. Take particular care to remove
any scaling from the float body and make sure that it moves
freely.
4. Sensor installation: Follow the appropriate steps of installation as outlined in the Installation section of this manual.
Testing the installation:
1. Power: Turn on power to the controller and/or power supply.

2. Immersing the switch: Immerse the sensing tip in its application liquid, by filling the tank up to the switches point of actuation. An alternate method of immersing the switch during preliminary testing is to hold a cup filled with application liquid up to
the switch's tip.
3. Test: With the switch being fluctuated between wet and dry
states, the switch indicator light in the controller should turn on
and off. If the controller doesn't have an input indicator, use a voltmeter or ammeter to ensure that the switch produces the correct
signal.
4. Point of actuation: Observe the point at which the rising or
falling fluid level causes the switch to change state, and adjust the
installation of the switch if necessary.
