ABOUT LFV
Trumen vibrating fork point level switch model
LFV suitable for all types of flow able liquids
in all process industries. It gives reliable
measurement and does not affected due to
material flow, vibrations in the tank, changing
the media properties and material build-up in
the sensor.
Trumen LFV available in three different design
like ½”, ¾” and 1” depends upon the mounting
requirements.

ABOUT TRUMEN
Trumen came into existence in 2009 and
initially started with manufacturing of Tuning
Fork Level Switches for liquid and solid
applications. With time, the manufacturing
range increased with addition of Capacitance

APPROVALS
Trumen vibrating fork point level switch model LFV is used in different applications like -
ITrumen vibrating fork is used in different applications like, Water, oil, milk, chemicals,
solvents and liquids having viscosity up-to 10,000Cp.
Suitable for hazardous liquids & chemicals.
Process temperature maximum 200° C / 250° C (available on requirement).
Operating pressure 20 bar maximum.
OPERATING PRINCIPLE
Electronics of LFV excites
the piezoelectric crystals
inside the tuning fork
which makes the fork tines
vibrate at their natural
resonance frequency in
free air.
When fork tines are
immersed in liquid, the
frequency of fork vibration
falls due to the density of
liquid.
This change in frequency
is detected by the
electronic circuit.
OPERATION
Open the cover of Trumen LFV you can see there are 9 terminals. Terminal
1, 2 & 3 are for auxiliary power supply. Terminal 4, 5, 6 & 7, 8, 9 are for relay
output.
Connect the power supply either 15 to 80VDC or 15 to 260VAC on
terminal 1 & 2 and plant earth on terminal number 3. Now switch on the power.
Trumen LFV starts vibrating in air. Power LED is on and status level is in OFF
condition.
Now fill the liquid up-to the fork tines level.
You can see the status LED of LFV is on means liquid reaches to the desired level.
Now empty the liquid, you can see the status LED is OFF means material goes
below the desired level.
Relay status also change from NC to NO.
There are 4 DIP switches provided on connection panel. Via DIP switch no.1 we can set the
sensitivity that means if the density of liquid is low density fluids we need to on switch
no.1 in this conditon LFV will sense the liquid. Keep it turned off for normal density fluids.
Switch no.2 is to set dry delay means off delay. ON the DIP switch no.2 and empty the
material. LFV will wait for 5 sec once the material goes below the sensor and after 5 sec it
generates switching. During the delay cycle sensor ignore the turbulence.
Switch no.3 is to set wet delay means on delay. ON the DIP switch no.3 and fill the
material. LFV will wait for 5 sec once the material touches the sensor and after 5 sec it
generates switching. During the delay cycle sensor ignore the turbulence.
Switch no.4 is to set failsafe means the instrument should be in alarm condition if the
sensor faces power failure. When the sensor is installed for high level keep the DIP switch
no.4 is turned off i.e failsafe high or maximum and when the sensor is installed for low
level keep the DIP switch no.4 turn on i.e. failsafe low or minimum.
You can easily replace the electronics as shown
