I want to continuously monitor the fuel level in this HONDA GX35 tank, as shown below. Can anyone suggest me an appropriate sensor for this ? enter image description here

P.S. : The tank is very small of 0.65L capacity. :(

  • \$\begingroup\$ Are you willing to program a microcontroller to handle the sensor and process its output signal, or are you looking for something off-the-shelf that you can buy? \$\endgroup\$ – Elliot Alderson Oct 12 '18 at 12:21

    \$\begingroup\$ The fuel might not be level - one of the selling points of the GX35 engine is "The world's first 360° inclinable 4-stroke engine, for operation in any position." Would it be acceptable to only be able to read the amount of fuel in one orientation? \$\endgroup\$ – Andrew Morton Oct 12 '18 at 12:49
  • \$\begingroup\$ It might be easier to simply keep track of the run time of the motor. \$\endgroup\$ – Dave Tweed Oct 12 '18 at 13:49
  • \$\begingroup\$ you could mount it on some force sensors and weigh it \$\endgroup\$ – D Duck Oct 12 '18 at 22:07

    \$\begingroup\$ Yes, basing it on run time will have inaccuracies, but it still might be the best available option. What are you using the motor for, and what kind of accuracy are you looking for? \$\endgroup\$ – Dave Tweed Oct 15 '18 at 13:13
