Any chance anyone could post some more bitstream data for tank depths other than 100% - I don't actually have this hardware, but trying to work backwards from the data posted.
I suspect the unit is sending back the distance between the sensor and the top of the water. The sensor wouldn't know how much water is in the tank (only the receiver knows this). Ideally, 3 or 4 sets different data - bitstream, reported depth, temperature along with the gap height and tank depth setting used in the receiver.
