Fuel Tank Level Sensor Arduino

Here is a home built capacitive fuel sensor for a paramotor.

Fuel tank level sensor arduino.

Vcc pin is the power supply pin for the sensor. How do you know when it s empty. Ultrasonic fuel tank level sensor also called non contact fuel meter is an electronic level transmitter measuring continuous liquid level fluid level or oil level. The recommended power of the water level sensor is between 3 3v 5v.

Analog output will vary depending on the voltage provided to the sensor. The arduino compares the reflected ultrasonic time with the reference time of the tank full height and creates an estimation of the instantaneous height or the level of the fuel. Supplies power for the sensor. It is based on a sensor made from an aluminium tube and rod and arduino microcontroller an lm3914 bargraph chip and 10 superbright leds.

It has been built for a parajet macro and the. Measure fuel level with arduino. The sensing unit usually uses a float connected to a potentiometer typically printed ink design in a modern automobile. As the tank empties the float drops and slides a moving contact along the resistor increasing its resistance 2 in addition.

S signal pin is an analog output pin and will always be connected to the analog inputs pin in arduino. The top countries of supplier is china from which the percentage of fuel level sensor for arduino supply is 100 respectively. Paramotor fuel sensor and gauge. Tankfulldepth the level at which you want the sensor to show 100.

If you look at the image above you ll notice that when the tank is full the liquid level will still be below the sensor maybe by about 15cm. If you have a fuel or water tank that is either metal or colored plastic you may have run into the same problem i had.
