Vibration Testing a Float Based Sender

Float based Fuel Level senders are not expected to see any vibration as the internal fluid is supposed to dampen the motion.

There are several critical applications where this is not  the experience in the field and people have turned to alternative technologies like - Capacitive or Ultrasonic fuel level sensors to get better performance

However -   Each one of these systems also struggles with agitated fluid  -

A float still rides on the surface giving the potential for an accurate reading no matter what is going on - The real issue with float sensors is not the float,  it is the method for recording the float position.    Resistance based senders wear as the contact rubs vigorously over the resistance trace.  Fluids attack the resistance grid and wiper

What if we kept the good part of this level sensor - the float and replaced it with a clever bit of electronics

Best of both worlds - Simple and Effective
