After doing a bunch of testing, it appears all the ToF sensors can be used to measure liquid.
the VL53L5 (L5) is slightly better at it due to the number of zones.
Only the photons that hit the water at very near 90 degrees reflect and do what you want. The rest penetrate the water, are slowed down by it, reflet off the bottom and basically make a mess.
The small zones of the L5 allow you to find a zone that returns more photons than the other zones and you can use only this zone informaiton.
If you have an L1 you can sort of do the same thing by narrowing down the Region of Interest and only paying attention to the photons that hit perpendicular to the water.
But you still have some work to do. Some photons will penitrate and if the water is shallow, the reflected photons will give you a bad reading.
In my work, I create a black bottom. I either paint it, annodize it, or make a clear container placed on a black shelf. This reduces the number of photons reflecting off the bottom.
