Where there are outfalls, vertical drops, baffles, curves or junctions, install the sensor upstream or
downstream as shown in
that is at least five times the pipe diameter or the maximum fluid level. For downstream locations,
install the sensor at a distance that is at least ten times the pipe diameter or the maximum fluid level.
If the location contains a junction and the flow in one pipe is much higher, install the sensor on the
wall near the lower flow pipe.
