In one of the more unique discharge applications around the world, the OTT MF pro flow meter is being used for discharge measurements in the Hessenhau Cave of southern Germany. The cave is the deepest known cave of the Swabian Alps at 472 ft (144 m) below ground. The cave is fairly new to exploration after only being discovered in 2006. Water flow tracer studies have connected water flow between area caves and the OTT MF pro is being used to measure the extent of that flow.
