External Fuel Tank Level Sensor

The reasons to use external fuel level sensor.

External fuel tank level sensor.

External mounted level sensors for installing on the outside of a liquid storage tank to measure level of tank contents. However when considering factors such as environmental obstacles chemical compatibility and pricing one sensor technology appears to rise above the rest. 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. Every sensor that is placed onto the tank wall consists of a shaker and accelerometer.

For a vented tank the pressure transmitter should be mounted to the bottom. For oil transporter tank or big tank fuel monitoring ultrasonic liquid level sensor is needed. Compared to voltage or pressure level sensor ultrasonic fuel sensor is more accurate and easy to install. 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.

This also means that monitoring the fuel level in the tank becomes an essential factor for the owner or the driver of the vehicle. 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. This project is only for experimental purpose. 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.

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. As you may already know there is a plethora of fuel tank level sensor technologies on the market. 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. These level sensors have a screw in clamp or bolt on flange fitting to attach the sensor to a connection port on the external wall of the tank.

The contol unit then calculates if the fluid level has passed the particular sensor or not. This design accommodates large or small tanks and vessels allowing use in a broad range of level measurement applications. 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.
