8.6 Temperature Sensor Installation
Connect device to a temperature sensor, the wiring connection is as below：
8.7 Ultrasonic Fuel Sensor Installation
The height measurement range of the ultrasonic fuel sensor is 0~100cm (0~250cm optional), and the
corresponding voltage output range is 0~5V.
VT140 analog input connect to the ultrasonic fuel sensor, the green wire of the ultrasonic sensor is connected to
the AD1 blue wire of the VT200 or the AD2 pink wire.
Example: When the fuel is empty, the sensor output voltage is 0V. With a fuel tank height of 100cm 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=H0/20
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
