That’s an approach I had not seen before. Thanks I will do a
few tests and work out the scaling.

Great road test Douglas.

I have been thinking about doing measurements of different materials and this device might be very useful.

I particularly like your 'out of the tank' measurements. I have experience doing out-of-container measurements with ultrasone (the ultrasone signal bounces against the border where the liquid meets air and echos back to the source).

It's nice to see your alternative.

I think your approach has the advantage of not requiring fast precise timers or a microcontroller - a decent sensitive capacitor measurement circuit would do. The downside is that you need build plates outside the container that go the full height.

With ultrasone, you need devices that can record the (very) fast response time of your ultrasone signal. On the other hand, you just need one sensor tagged to the outside bottom of the container.

I wonder how the precision between the two mechanisms compare...

Wonderful video. I learn a lot by the testing you did. Thanks.
