Discharge - Current meter Ott C2

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
