Introduction / Table of Contents Step One
ABOUT SWITCH-TEK™ VERTICAL BUOYANCY LEVEL SWITCH
The Vertical Buoyancy Switch consists 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 to
change.

Safety Precautions Step Three
About Manual: PLEASE READ THE ENTIRE MANUAL PRIOR TO INSTALLING OR USING THIS
PRODUCT. This manual includes information on the vertical buoyancy, model LV10-_3_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 switches and
technologies. While each of the 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 over tighten
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 the cable jacket are made of Polypropylene (PP) for the LV10-13_1. The switch is made of
Polyvinylidene Fluoride (PVDF) and cable jacket is made of Fluorinated Ethylene Propylene (FEP) for the
LV10-53_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.
Temperature and Pressure: The LV10 series switch is designed for use in application temperatures up to
80˚C, and for use at pressures up to 25 psi (2bar) @ 25 ˚C., derated @ 1.667 psi (.115 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. For CE applications, 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
Avoid installing the LV10 in magnetized metal tanks. Doing so will activate the internal reed switch.

Installation Step Four
TOP WALL INSTALLATION
FLOWLINE’s LV10 switch may be installed through the top wall of a tank. For Smart Trak (LM10 series)
installations, remove the sensors thread and use the bayonet adapter to interface to the LM30 series Switch
Car. For Switch Pak™ (LM45 series) installations, use the 3/4” thread as the interface.
Bayonet Connection: The ¾” thread can be
removed to access the bayonet connection. Simple
press down on the threads and twist to release.
Orientation: Mounting orientation bust be kept
vertical for proper orientation. The vertical buoyancy
and float switches are orientated in vertical position
±20˚.

Installation Step Four
CONNECTION TO A SWITCH CAR KIT (LM30 SERIES)
In order to attach the LV10 series to a Smart Trak (LM10 series) fitting, a Switch Car Kit (LM30 series) is
required. The LV10 series can be attached in two ways, without the bayonet adapter and with the bayonet
adapter.
Without Bayonet Adapter With Bayonet Adapter
The use of the bayonet adapter will increase the overall length of the LV10/LM30 series assembly. This will
result in a lower activation point within the tank due to the added length. It is recommended to remove the
bayonet adapter when interfacing with Smart Trak.
First, remove the bayonet
adapter by pressing down
twisting the adapter.
Next, thread the sensor wire through the O-ring and the
sensor car and out through the hole between the sensor
car shoe and the locking bolt. Set the O-ring into the
LV10. Push the sensor into the bayonet side of sensor
car. Screw the bayonet adapter onto the sensor until the
sensor seats against the pit inside the adapter.

Electrical Step Six
VOLTAGE
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. Alternate
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 well insulated, 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 striper, remove the last 1/4" of the colored insulation from the signal
wires.

Wiring Step Seven
WIRING TO A FLOWLINE CONTROLLER
LC40 Series Controller (LC42-1001 Shown) LC10/LC11 Series Controller (LC11-1001 Shown)
NOTE: When using a latching relay, the polarity of both switches must be the same. Either both switches are
wired Normally Closed (Red & Black – See Relay #2 with LC42) or both Normally Open (White & Black – See
Relay #1 with LC11).
VERTICAL BUOYANCY LEVEL SWITCH (LV10-_3_1)
The LV10-_3_1 switch can be wired normally open or normally closed for your application requires.
Normally Open
Use the Black and White wire for operation the LV10_3_1 in a 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
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 closed when the float is
dry and open when the float becomes submersed.
This operation is typical for indicating a low level.

Maintenance Step Eight
GENERAL
While a filter should protect the float from particulate contamination, the switch may need to be cleaned
periodically to prevent jamming of 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.
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 it slightly to disconnect it from the buoyancy net 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
switch. An alternative method of immersing the switch during preliminary testing is to hold a cup filled
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,
a. Use a voltmeter with a power supply in series to measure an open or closed circuit.
b. Use an ohmmeter in series to measure an open or closed circuit.
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.
EXAMPLE
Testing the LV10 series with a Multimeter set to read Volts. When wired NO (Black and White), the meter will
read 0 volts when dry and full voltage when wet.
