2. Product Description
VT100-L is a 4G based vehicle GPS Tracker with built-in high-precision, GPS+BDS dual-mode positioning module;
It integrates functions of driving behavior monitoring, remote fuel cut, low power alarm, external power
disconnect alarm, various abnormal alarms, electronic geo-fences etc., and uploads information to the platform to
create comprehensive supervision and security for vehicle driving. By its ultra mini size, it is easier to install and
hide, which is suitable for the automotive risk control industry, vehicle supervision, anti-theft and shared travel
industries.
VT100-L has a built-in 16Mb Flash memory. When the device enters a place without network, it will automatically
save the historical positioning data. When the network returns to normal, it will automatically resend the historical
positioning data to the tracking platform.

For example, as above parameters setting, if the fuel tank connected to AD1 decreases more than 20 liters within
60 seconds, an fuel theft alarm will be generated; and if the fuel volume is less than 10 liters, a low fuel alarm will
be generated.
Example: The fuel tank height is 100cm and full fuel is 50 liters, GPRS data as below:
&&A147,021104023195429,000,0,,180106093046,A,22.646430,114.065730,8,0.9,54,86,76,326781,460|0|27B3|0EA

AD1 voltage is 0x01C8 (hexadecimal)=456 (decimal), AD1=456/100 (fixed value)=4.56V;
AD2 voltage is 0x0000=0,AD2=0/100=0V;
Example: Connect the GPS Tracker analog input to capactive fuel sensor, the yellow-green wire of the sensor are
connected to the white wires (AD) of the VT100-L.
When the fuel is empty, the sensor output voltage is 0V, when the fuel is full, the sensor output voltage is 5V
Calculate the percentage of remaining fuel:
Fuel percentage=(AD/5)*100%=(4.56/5)*100%=91.2%.
Calculate the remaining fuel in liters:
The remaining fuel in liters = (AD/5) * 50 liters = 45.6 liters

8.4 Ultrasonic Fuel Sensor Installation
8.4.1 Connect ultrasonic fuel sensor to VT100-L AD
Take the analog input of VT100-L connected to the fuel sensor as an example, the green wire of the sensor is
connected to the IN1 white wire of VT100-L (Need to configure IN1 as AD1 by parameter editor) or the IN2 orange
wire (Need to configure IN2 as AD2 by parameter editor)
① The height measurement range of the ultrasonic fuel sensor is 0~100cm (0-250cm optional) , and the
corresponding voltage output range is 0~5V.
If the height of the fuel tank is H0cm and the fuel tank is full of F liters, the fuel sensor output voltage is V=H0/50
when the fuel is full.
Calculate the remaining fuel volume:
Percentage of fuel = (AD/V)*100%
The fuel volume height is: H=(AD/5)*100cm
The remaining liters of fuel volume = (AD/V)*F liters
② he height measurement range of the ultrasonic fuel sensor is 0~250cm , and the corresponding voltage output
range is 0~5V.
Example: When the fuel is empty, the sensor output voltage is 0V. With a fuel tank height of 250cm as the
standard, then fuel sensor output voltage is 5V when fuel is full.
If the height of the fuel tank is H0cm and the fuel tank is full of F liters, the fuel sensor output voltage is V=H0/50
when the fuel is full.
Calculate the remaining fuel volume:
Percentage of fuel = (AD/V)*100%
The fuel volume height is: H=(AD/5)*250cm
The remaining liters of fuel volume = (AD/V)*F liters

7,27,0000000F,02,01,04E2|018C|00BA|0000,1,0104B0, 46\r\n
The voltage value of the AD1 is 0x00BA (hexadecimal)=186 (decimal), AD1=186/100 (fixed value)=1.86V;
The voltage value of AD2 is 0x0000=0, AD2=0/100=0V;
The output voltage when the fuel is full = H0/50=100/50=2V
Percentage of remaining fuel=(AD1/2)*100%=(1.86/2)*100%=93%
Height of remaining fuel volume:H=(AD1/5)*250cm=(1.86/5)*250cm =93 cm
The remaining fuel volume in liters = (AD1/2) * 50 liters = 45.6 liters
8.4.2 Connect ultrasonic fuel sensor to VT100-L RS232
Note: need hardware customization, the software version is only supported in V113 standard version and above
After connecting the wires and powering on, set the parameters:
8.4.2.1 Set parameters through parameter configuration software or SMS commands:
①. Configration by Parameter Editor:
Select "Ultrasonic Sensorr" and set the data source of the fuel tank (select RS232-1/2), the sensor type is ultrasonic
fuel sensor (Ultrasonic(100cm)/(250cm)), the size of the fuel tank (length, width, height) these parameters, then
the tracker can obtain the remaining oil value

If the remaining fuel volume read by the tracker is L0 liters, the full fuel is F liters, and the fuel tank height is Hcm,
the percentage and height of remaining fuel volume can be calculated:
Percentage of remaining fuel = (L0/F)*100%
The height of remaining oil is: H0= (L0/F)*H
Take the fuel tank height of 200cm and full fuel of 60 liters as an example of GPRS data:
&&k147,860262050015374,000,0,,210814070734,A,22.678986,114.046146,12,0.9,0,279,13,65,460|1|2609|061E278
3,31,0000003F,00,00,049 ,01001F,,D6\r\n
01001F: 01# fuel tank; 0x001F, the decimal value is 31, and the remaining fuel volume is 31/10=3.1 liters
Percentage of remaining oil = (L0/F)*100% =(3.1/60)*100%=5.17%
Height of remaining oil volume: H0= (L0/F)*H=(3.1/60)*200cm =10.4 cm
8.4.2 Set fuel theft alarm and low fuel alarm
After connected wires, can set the size of the fuel tank (length, width, height), sensor type (capacitive fuel sensor
or ultrasonic fuel sensor), fuel theft time, low fuel alarm by Parameter Editor.
1) Configuration by Parameter Editor: Set the fuel tank name to Right Tank; The data source of the fuel tank is
