External Fuel Tank Level Sensor

Ultrasonic sensors measure the height of the fuel in the tank by sending out ultrasonic signals which are measured on the other side of the tank via another sensor.

External fuel tank level sensor.

Every sensor that is placed onto the tank wall consists of a shaker and accelerometer. The most popular application for ultrasonic level sensors is measuring level in a body of liquid be it in a tank well pit or lake. Compared to voltage or pressure level sensor ultrasonic fuel sensor is more accurate and easy to install. This project is only for experimental purpose.

Although most vehicles are already equipped with an advanced digital fuel sensor indicator device building your own circuit can be a lot of fun and satisfaction. For oil transporter tank or big tank fuel monitoring ultrasonic liquid level sensor is needed. As you may already know there is a plethora of fuel tank level sensor technologies on the market. The reasons to use external fuel level sensor.

Fuel tanks typical having diesel tanks or gasoline tanks on vehicles are often on moving or running thus if external ultrasonic fuel level sensors are not equipped with excellent signal processing technology users may find they can t get right data and no stable data output etc. External mounted level sensors for installing on the outside of a liquid storage tank to measure level of tank contents. To say that one is better than all the rest would be rash as each fuel level measurement application has its own unique set of challenges. However when considering factors such as environmental obstacles chemical compatibility and pricing one sensor technology appears to rise above the rest.

For a vented tank the pressure transmitter should be mounted to the bottom. But most of our ultrasonic level sensors are either used for liquid level open channel flow or for presence detection and object profiling where they perform very well. Designed for single point tank monitoring side mount level sensors can be mounted from inside the tank and outside the tank using a compression grommet or tapped hole. Gauge and differential pressure transmitters are reliable cost effective instruments to measure the hydrostatic level of liquids such as water or fuel in vented or sealed tanks.

On the other hand when capacitance sensors are used the fuel passes through special vents when it consumed causing the capacitance to change in the sensors enabling the level of the fuel in the tank to be determined. When the shaker creates a vibration in the tank wall the accelerometer measures the size of the vibration and passes it on to the control unit. The contol unit then calculates if the fluid level has passed the particular sensor or not.
