The hand-held MiniWater®20 is a:
The MiniWater®20 hand-held measuring instrument with the MC20 operating and display unit serves to measure the flow velocity of surface waters such as rivers, brooks, lakes, canals, etc.
Ergonomic user guidance and local data storage allow versatile application of the unit. The MC20 microcontroller is used as an operating and display unit which the MiniWater®20 measuring sensor recognises automatically when it is plugged in and converts the rotation frequency of the measuring turbine into the m/s unit of measure.
A typical set-up consists off:
You can choose among the following Water-flow sensors:
MiniWater®20 measures the flow velocity of water. A measuring turbine with a rotation frequency depending on the water velocity is used as a sensor. This frequencey is converted into an analogue output that is displayed in m/s.
