Compatibility
- In case of uncertainty or errors always consult the original equipment manufacturer.
- In order to deliver the right module, we ask the customer to provide the vehicle type (modell, construction year) prior to the delivery.
- If the manufacturer has no data for this modell, it is necessary to communicate the fuel tank size (in litres) and to measure the ohm value when the tank is full and the ohm value when the tank is empty.
- If you don’t provide this data, we deliver a device with standard settings which might be wrong.
- NO proper functioning with vehicles with 2 tanks or if the sensors don’t deliver OHM values.
Technical Data
STG-6: normal measurement
0 Ohm = Tank empty / > 80 Ohm = Tank full
STG-3: inverted measurement
0 Ohm = Tank full / > 80 Ohm = Tank empty
Fuel monitoring for 12/24V vehicles with 0..1kΩ - fuel sensors
Only is active when ignition is OFF
How it works;
The modulles STG-3 and STG-will be activated when ignition is OFF and measure the fuel level after a while. If the fuel level decreases, alarm is triggered to the tracking device
Ohm values
You can measure the ohm value with an Om-Meter. Connect it to the fuel sensor. If the floater is down (empty), you get the ohm value for the empty tank. If the floater is up (full), you get the ohm value for the full tank.
The list below is subject to change without prior notice by the manufacturer.

PIN 8 | Fuel sensor (+ Plus) |
PIN 9 | Alarm/GSM connect with negative trigger input of tracking device ( in case of alert ground is activated) Make sure to use a negative input or to contact the supplier! |
Installation instructions
- Install it at a safe place (protected from water or heat)
- Use a 2 Ampere fuse.
- Ohm values on the module must be similiar to the values on the fuel sensor
Final tests for correct delivery
see Installation Tests and Reporting
Make sure that the alarms are working prior to handing over the vehicle to the customer:
- If the ignition is OFF and the fuel tank is depleted, the alert must come within 2-5 minutes (PIN 9 output must show ground for 10 seconds).
- If PIN9 is activated (ground signal), then the GPS Fleet Software must show an alert or input change on one of the digital inputs:
Troubleshooting
Please check,
- If the ohm values increase when the fuel tank is lowered or if the ohm values decrease when the fuel level is lowered. .You can also move the floeter of the fuel sensor from top to down to see the ohm value change
- If the ohm value change of the fuel sensor can also be measured at the fuel securing module
Adjust the tolerance:
Turn the module as in the picture shown below:
Do 5 turns clockwise to get a higher tolerance (less alerts).
Don’t turn the screw anti-clockwise.
