RL level for a sump in mining

Hello,

Would like to monitor the water level of a sump in a mine pit
Any ideas on devices that may be able to talk to a miri AD2006 telemetry unit?
Would like to place it floating in the pond.

One of these maybe?

Thanks mate, we do use these a lot, I was looking for something to give a realtime x,y,z location, rather than having to calibrate a transducer to parameters if that makes sense?
