    Good to hear. and definitely very interested in use with a flume.  What range of water depth measurement are you looking for and depth accuracy of measurement.

    Typically, because  ADCs are not good around 0.0V and rail – the Sensor range from 0.0 to full range, the Voltage range is from 10%Rail to 90%Rail (eg 0.3V to 3.0V for 3.3VDC rail) and typically wants to be ratiometric. That is the ADC voltage VREF is the same as that used by the sensor.  The other way of adjusting that is that the measuring device has a greater range than the actual range of measurement. That is 0.0  is less than the flume entrance.

    Resistance  varies with temperature (as everything in the universe varies with temperature)- so they haven’t listed what the temperature dependency is.   It might not be much in the water, and may need a reasonable shield for that out the water.

    How are you looking to power it, Are you looking to report it wirelessly?   Standard ModularSensors is best effort in both cases.
