ABOUT TRUMEN
Trumen vibrating fork point level switch model
LFV suitable for all types of ?ow able liquids
in all process industries. It gives reliable
measurement and does not affected due to
material ?ow, vibrations in the tank, changing
the media properties and material build-up in
the sensor.
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 Level Transmitter
Capacitance Level Switches, RF Admittance Level
Switches, Rotating Paddle Level Switches,
Conductivity Type Level Switches, Vibrating Rod
Level Switches, Hydrostatic Level Transmitter,
Radar.
Trumen LFV available in three different design
like ½, ¾ and 1 depends upon the mounting
requirements.

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 Device operation and settings
Trumen LFV is very easy to operate
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 ?ll 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 ?uids we need to on switch
no.1 in this conditon LFV will sense the liquid.
Keep it turned off for normal density ?uids.
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 ?ll
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 In case
