I tested a range of different pipe sensors at the start of this project back in April 2019:

I wanted to use the small clear sensor shown on the far right, however it could not measure slow moving water. The first sensor I built that was used for field work in a test was using the DN50 (the large black sensor, centre left of the image). But it still did not perform well in slow moving water.
The current build is now using the DN80, the one on the far left of the above image.
