Introduction
LV3000 and LVCN410 Series
Continuous Level
Measurement
The LV3000 Series Capacitance Level Measurement System is designed to
measure and control the level in most industrial applications. The probe
works in conjunctionwith the Series of levelcontrollers. The is
available in 316SS with optional ETFE tubing or ECTFE coatings (required for
conductive or aggressive mediums). The LVCN410 controller with an integrated
bar graph display gives the operator an overview of the level within the vessel.
With 4...20mA output signal and up to 2 Relay switch outputs, this system
provides a complete level control solution for mostapplications.
How it works:
A capacitor consists of the probe’s rod as one plate and the metallic wall of the
vessel (or a secondary reference rod or sheath) as the other plate. As the
medium rises and displaces the empty space within the vessel, the dielectric
constant around the probe changes. This change is recorded andconverted into
either a relay switch output or a 4…20mA output signal which is proportional to
the level withinthe vessel. By using this principle, the + Series
can be applied in a wide range of products such as most liquids, powders,
pastes and granular mediums.

Mounting Notes
Mediums that are conductive will cause a short
circuit between a bare stainless steel probe and
the tank wall. For that reason we recommend
the use of ECTFE or other types of insulating
coatings on the rod's surface. (Fig. 1)
Material build-up also affects the accuracy of
RF capacitive measurements, and therefore
additional adjustment to the probe's sensitivity
is recommended in applications where build-up
is a concern. (Fig. 2)
Housings must also be compatible with the
requirements for wash-down, wet, and/or dusty
environments. Hazardous environments may
require the housing to be certified. In addition,
the active probe might need to be intrinsically
safe or have an intrinsic safety barrier. (Fig. 3)
The electronic circuitry of the probe performs
several functions such as rectifying and filtering
the incoming power, generating the radio
frequency signal, measuring the changes in
current flow, analog signal generators and
display meters. The circuitry is provided with
potentiometer adjustments for setting
sensitivity that is located in the housing of the
probe. These adjustments give an added level
of fine-tuning which enable the user to control
the probe's sensitivity with greater accuracy.

Mounting Notes
When making connections between the controller and the probe use
reliable cables and make sure they are grounded.
Shielded cables prevent interference improving and protecting against
false measurements.
Do not install the controller in harsh environmentsand humidity.
Respect class protection, working temperature and protect the same
from rain and excessive heat.
A stable power supplyprevents damage and equipment malfunction.

Installation
When installing the probe either directly to the
tank, or utilizing a connection, the capacitance
probe should be mounted on the top of the tank,
never on the side or angle, so that the rod stays
parallel to the tank wall.
(Fig. 1 correct Fig. 2 Incorrect)
The mounting location of the probe should stay
clear away from the point where the medium
enters, this will avoid false reading from the sensor
while being filled.
(Fig. 1 correct Fig. 2 Incorrect)
The recommended distance of installation of the
probe from the internal wall is a minimum of
500mm, and from the tip of the rod to the bottom of
the tank is 100mm, this will prevent a false signal
and possible build up between the wall and probe.
(Fig. 1 correct Fig. 2 Incorrect)
For high pressure and explosion proof
Note:
applications, care should be taken when tightening
the connection as achieving a proper seal is very
important.

Rod
Level
Referrence Rod
In order to achieve a linear output
signal, the main rod of the probe
must have a parallel reference
either to the tank or to a
secondary reference rod or
sheath. If the probe is mounted
without this parallel reference
within a cylindrical tank that is
mounted on its side, the output
signal will not be linear. Please
consult one of our application
engineers if you have further
questions.

Sheath
The tank must be free from turbulence or

possible we highly recommend a stilling
well or sheath.

Ensure that mounting position does not
interfere with any obstructions wthin the

When installing the LV3000 with cable and
reference be sure that they are well connected
to the bottomof the tank and that it hasno slack.
(Fig. 1 correct Fig. 2 Incorrect)
The mounting location of the probe should stay
clear away from the point where the medium
enters, this will avoid false reading from the
sensor while being filled.
(Fig. 1 correct Fig. 2 Incorrect)
The recommended distance of installation of
the probe from the internal wall is a minimum of
500mm, and from the tip of the pendulum to the
bottom of the tank is 100mm, this will prevent a
false signal and possible build up between the
wall and probe.
(Fig. 1 correct Fig. 2 Incorrect)
If the cable is secure to the bottom of the vessel
it must be isolated and the vessel is steel it must
be isolated so that it does not create a short
circuit.

LVCN Controller Calibration
Adjustment 4mA
It is recommended that an multimeter be connected
according to the figure(fig.4) to monitor the current
value during the calibration. Prior to calibration it is
recommended that both potentiometers are reset.
Turn both potentiometers counter-clockwise or
approximately 5 turns. (Fig. 1)
The bargraph is calibrate according to the signal
(4mA-0% and 20mA- 100%).
1) Drain the tank to minimum level (Zero%or 4mA).
2) Select the Sens. switch 1,2,3 located in the probe
Unit LV3000. It is recommended to begin with Sens.
switch 1. (Fig. 2)
3) Use the Zero potentiometer to set the current
value for the actual level to 4mA or 0%. Turn the
potentiometer clockwise to increase current. Turn
the potentiometer counter-clockwise to decrease
current. If you are unable to set the probe at 4mA,
alter the Sensitivity potentiometer (Fig.2) position
and try to adjust the minimum value (4mA) through
the Zero Potentiometer again. (Fig.3)

Adjustment 20mA
After calibrating the minimum value (4mA or 0%), fill
up the tank to maximum level (100% -level).
4) Use the Span potentiometer to set the current
value for the actual level to 20mA or 100%. Turn the
potentiometer clockwise to increase current. Turn
the potentiometer counter-clockwise to decrease
current (Fig.5).
5) If the current is lower than 20mA or 100% after fully
turning the Span Potentiometer clockwise, it is
necessary to increase the sensitivity by selecting the
next level of the switch ( Sens.). If the current still
remains lower than 20mAor 100%, continue on to the
next level until achieve 20mA.
6) With the 20mA or 100% signal adjusted itis best to
re-adjust the Zero. Drain the tank back down to the
starting level and re-adjust (if necessary) the
minimum level to 4mA or 0% one more time. After
this stage, set-up is complete.

LVCN410 Calibration
LVCN410 Set-Point adjustment
After completed the calibration, it is necessary to be done
to adjust the set-point outputs of the case is used.
LVCN410 controller has 2 outputs Relay (SPDT),with indication
LOW and HIGH. To adjust, make sure the outputs are not
actuated (statement made by the LED’s), if necessary turn
the potentiometers clockwise (fig.1).
1) Low Level Control.
Fill the tank to the first point , then turn the potentiometer
(Low) counter-clockwise until the LED indicator turn-on.
2) High Level Control.
Fill the tank to the second point, then turn the
potentiometer (High) counter-clockwise until the LED
indication turn-on.
With two adjusted points, confirm the points draining and
filling the tank until the set-points, re-adjust if necessary.

Handling
Probes:
Seal the thread with Teflon tape before
installation. (Fig. 1)
®
Fig. 1
Do not turn or handle by the housing. (Fig. 2)
When tightening the sensor, use only use the
316S.S. hexagon fitting to achieve a seal, do not
twist with the body of the sensor. (Fig. 3)
The probe should not be dropped or suffer any
impact or fall that could damage the electronics or
the coating of the probe. (Fig. 4 and5)
Periodic visual inspection of the probe is required
to check for corrosion or deposit build-up. If
deposits are found, clean the sensor to ensure
optimum performance.
Care should be taken when handlingand installing
probes with coated rods to avoid scratching them.
Scratching the coating could interfere with the
probe performance.
