KC - Digital Flow Meter with Back-Run Stop

Can be used for full oceanographic depth. (free flooding).

Rigging instructions:
Installation of the digital flow meter is made by a triple point connection of the nose piece inside the net ring.
Determination of the water volume passing through a plankton net

The digital flow meter incorporates a three blade impeller coupled directly to a five-digit counter which records each revolution of the impeller.

Please note that the counter cannot be reset to "0". Before operating the unit, you must note all figures. The number of revolutions is read by noting the difference in beginning and end readings.

The pitch of the impeller is 0,3 m per revolution, i.e., the number of revolutions multiplied by 0.3 makes the towing distance.

For quantitative measurements the threshold flow velocity of the impeller should not be smaller than 0,5 m/sec. For comparison measurements flow velocities smaller than 0,5 m/sec are possible.
