Other Parts Discussed in Thread: FDC1004, TDC1000

Looking  for a sensor to translate a fuel level to a digital plus.

Informatively, the sensor has to attach to the fuel display (2x3 inch window).

    Hi John,
    I would recommend checking out FDC1004. Here is the link to the datasheet: www.ti.com/.../fdc1004.pdf. Also the following is a good resource on fuel level sensor: e2e.ti.com/.../412538. I hope this helps!

    Best Regards,

    Hello John,

    We can use our Ultrasonic Based solution to detect and display the fluid levels.

    Please refer to the application note "Ultrasonic Sensing Basics for Liquid Level Sensing, Flow Sensing, and Fluid Iden (Rev. A)" using TDC1000 device in the link below:

    The sensor has to attach to the fuel level glass(no attachment to fuel or fuel wiring).
    The sensor has to translate the level in which fuel reads.

    Hi John

    The ultrasonic sensor level approach can be used outside the container but it depends on the type of container and transducer used. The application note above describes that. You will need to experiment and check the signal that you get. The TDC1000 is only the analog front-end IC. To build a complete sensor/system, the device needs to be coupled with a transducer, a micro controller and a display, if needed. Same is true for the FDC1004 approach as well.

    Here is my issue;
    My sensor either need to see the fuel level(without any attachment) or attach to fuel tank(without a wire or sensor inside the tank).
    The reason for it ;
    If there is any hard wire; the design has go through two years of testing and approval!
    I need to attach a sensor out side the tank and design a blue tooth board and tell the operator how much fuel is left!

    Hello,

    Both solutions presented above do not need the sensor to touch the fuel or wiring to put inside the tank. The sensor is attached outside. As said earlier, the performance of the solution will depend on the tank material and shape. This is something you will have to try out yourself and see which works better for you.

    We don't offer a complete solution that can be directly clamped on and the output given to a bluetooth transmitter. You will have design it using either the FDC1004 or TDC1000 device and a micro controller. Please refer to application notes for liquid level sensing for both devices.
