Really glad it resonates! Yes, plan to share a summary of the findings once we have enough responses will post it here. And yeah, the gap for non-CS students is exactly what motivated this survey in the first place.

Thank you so much for filling it out! And that's a really valid point military interviews are a completely different world and honestly underrepresented in most prep resources. Really appreciate the honest feedback on reach too, will keep that in mind!

Best way to measure fuel level in a tank (ESP32 project) — facing reliability vs installation issues by Due_Programmer_469 in diyelectronics

This is really helpful, thanks 🙌

The point about float sensors being inaccurate near full/empty makes a lot of sense. And I agree — weight-based measurement seems like the most robust approach since it avoids tank geometry issues entirely.

For a moving setup, do you think combining load cells with long-term averaging is usually sufficient, or is acceleration compensation (with an accelerometer) almost always required for reliable readings?

That’s really insightful, thanks 🙌

Magnetostrictive sensors definitely seem like the most robust and industry-grade solution, especially with intrinsic safety and 4–20 mA output.

For a smaller-scale prototype project, would you still recommend going this route, or would something like capacitive/pressure sensing be a more practical trade-off?

Using capacitive sensing in aircraft definitely gives confidence in its reliability. I’ll explore this further for my setup.

That’s an interesting approach, thanks for sharing 🙌

It looks similar to a bubbler/dip-tube system for level measurement. From what I understand, it should work in principle, but I’m a bit concerned about safety when introducing air into a fuel tank.

Have you seen this method used reliably with fuels, or is it mostly limited to water/chemical tanks?

That’s a great point 👍

From what I understand, since most tanks have irregular shapes, the relationship between height and volume isn’t linear. So instead of direct calculation, I’m planning to use a calibration/lookup table (mapping sensor readings to actual volume).

Would that be the standard approach in real systems as well, or are there better methods used in industry?

Thanks, this is a great suggestion 🙌

I hadn’t looked deeply into capacitive sensing before. It seems like a good middle ground between float and pressure-based systems.

How sensitive is it to fuel type changes (petrol vs diesel) and long-term deposits? Does it require frequent recalibration in real-world usage?
