QT series tipping bucket flowmeter
Product description: Surface runoffis the flow of water that occurs when excesswaterfromrain,meltwater, or other sources flows over theearth's surface. This might occur becausesoilissaturatedto full capacity, or because rain arrivesmore quickly than soil can absorbit. Surface runoff is a major component of thewater cycle. It is the primary agent insoil erosion by water. QT series tipping bucket flowmeter can be used to monitor no-pressure, low-head, and small discharge flow of surface or underground runoff.
