Discription
Note
1
Remove fuel: Remove all fuel from the tank.
Some tank have been welded with oil filter and
have float level sensor installed, so it is
necessary to take out the float level sensor
before removing the fuel.
2
Clean the tank
Must clean the tank thoroughly.
3
Central hole locating: The hole will be in the
center of tank's up-per side or closest to
center.
This is an important step as it will directly
affect the stability of the fuel level data.
4
Drilling the central hole:
After determining the center of the oil
tank, we clean the surface and use a 38
mm drill to make a hole on the oil tank.
Remove any burrs from the drilled hole
by a file.
Before drilling, it is vital to check whether the
hole is affected by the internal metal frame or
obstacles at the bottom the tank.
5
Flange installation:
Place the 4 mm rubber gasket at the
center of the tank's upper side.
Place the plastic flange onto the rubber
gasket (4 mm).
Mark 4 points at the bolt hole.
Use screws /rivets to fasten the 4 mm
rubber gasket and the plastic flange
onto tank.
Only using screws for the thick and hard
tanks.
Unplug the screw/ rivet symmetrically.
8. Sensor Installation Guidance

6
Sensor cutting:
After flange installation, we determine the length of the sensor to be installed as picture below:
C = L+20+20-(H+14) => C = L+26-H (mm)
C: Length to be cut.
L: Original length of the sensor.
H: Height of the tank.
*Example:
Sensor length is L = 2000, H = 1700 mm => C = 326 mm => Cut the sensor pipe length of 326
mm.

7
Calibration:
After cutting, make sure the sensor tube is clean.
Re-plug the Filter footer and tighten the screw.
PLEASE FOLLOW THESE STEPS IN ORDER:
GET ZERO (4mA): After cutting, clean the probe, put the probe in the media at
expected level near the bottom or leave the probe at dry condition, press CALIB
button in 0.2 - 3 seconds, the LED will always ON in this press time.=> ZERO is
achieved, output current = 4mA.
GET SPAN (20mA): Put the probe in the media to the expected upper level then
press CALIB button in 3-6 seconds, the LED will ON then OFF.=> SPAN is achieved,
output current = 20mA. In 30 seconds without pressing the CALIB button, the
sensor will turn back to OPERATION mode.
8
Final:
Place the O-ring on the top of the threads, ensure that it can touch the aluminum housing
of the sensor (as below picture):
Install sensor into the threads of flange and turn it in clockwise direction.
Using the O-ring enables to rotate the sensor within 180 degrees from final tighten
position and assuring that the oil will be not spilled (as below picture):
Use the 2mm Allen key to lock the hex bolt to protect the sensor rotate backwards.
Connect the sensor with the cable.
Use sensor head seal to cover the sensor and then use plastic and then use plastic twister
seal to lock the head seal and connector seal to protect the sensor.
Please follow the below steps:
Note
Step 1: Remove the cover
Step 2: Remove the terminal connector
Step 3: Use the 2 mm Allen key to unlock the hex bolt
Step 4: Turn the sensor in counter-clockwise direction
Do not hold the male connector to rotate sensor directly, that
can make the male connector broken.
Do not use locking pliers, pipe wrenches, etc. to twist the sensor
as this cause damages the structure of the sensor such as cast
aluminium housing, label, signal cables (connector), circuit
board, ect. and it will not be covered under warranty.
M12-Female Connector
1. PWR+ (RED) : 8...50 VDC
3. GND (BLACK): 0 VDC, Ground
2. A (White) : Output 4-20mA
4. B (Green) : Not Using

10. Wiring
10.1 M12-Male Connector of Sensor
10.2 Follow Labels on Wires

Each cable includes wires which are marked labels according to types of connection. (user should not cut these labels
before installation to avoid confusing)
Red: PWR+(8...50VDC)
Black: PWR-(OVDC)
Green: Not Using
White: Output 4-20mA
Recommend to use 24VDC power.
The signal cable from sensor should be protected by corrugated hose or the Φ16 plastic tube, keep the cable avoid
high temperature areas.
Depending on the type of oil tank, we have different calibration of the corresponding oil quantity. Refer to the excel file
below to calculate the volume
PulseCAP10 with 4-20mA Output has an advanced feature is Field Calibration. Field Calibration allows customers to
calibrate the sensor after cutting. It will works with many non-conductive media such as Vegetable Oil, Non-standard
Diesel, Light Fuel Oil... To enter Calibration Mode: press the CALIB button on top housing 3 times, time interval
between press not greater than 1.5 seconds. LED will blinked at 5Hz in Calibration mode.
GET ZERO (4mA): After cutting, clean the probe, put the probe in the media at expected level near the bottom or
leave the probe at dry condition, press CALIB button in 0.2 - 3 seconds, the LED will always ON in this press time.=>
ZERO is achieved, output current = 4mA.
GET SPAN (20mA): Put the probe in the media to the expected upper level then press CALIB button in 3-6 seconds,
the LED will ON then OFF.=> SPAN is achieved, output current = 20mA. In 30 seconds without pressing the CALIB
button, the sensor will turn back to OPERATION mode.
10.3 Follow Wire Colors
11. Configuration
11.1 Calculate 4-20mA of oil tank
EXCEL FILE CALCULATE VOLUME OF OIL TANK
11.2 Calibration 4-20mA
It is recommended to use a PVC plastic tube and oil to calibrate the 4-20mA before inserting into
the oil tank
PLEASE FOLLOW THESE STEPS IN ORDER:
12. Connect with LFC128-2

1. Periodically clean the oil tank 2, 3 or 6 months depending on usage and contamination.
2. Periodically clean the sensor and filter footer 2, 3 or 6 months by:
Cover a sensor's vent before using the air sprayer for another.
Remove and clean the filter footer.
No.
