Parameter to be measured:
Flow velocity (discharge)
Method:
propeller
Equipment:
C2:
- propellers
- axle
- wading rod
counting unit (e.g. Ott Z400)
Advantages:
- simple no-fuss mechanics
- "sensor" (propeller) response is directly visual
- comparatively small case including wading rods
Disadvantages:
- poor response in low velocities
- maintainance of ball bearings (oil)
- mechanical vulnarability
- no immediate calculation of discharge, no data storage?
What to watch out for:
- submerged weeds, low velocities, piranhas
Price:
- ~ 8000 € (2008)
