Description
For determining the amount of water passing through a plankton net or a pipe.The back-run stop is recommended for a vertical tow of the plankton net. When lowering the net, the flow meter does not count; it will only count when the net is drawn back through the water column. For a horizontal pull, you can also use flow meter 23.090.
Diameter of propeller/counter body: 70/32 mm, length 185 mm, 5-digit counter; easy installation by a triple point connection of the nosepiece.
The construction is based on a free flooding design, so it can be used for full (unlimited) oceanographic depth.
