About
The 23.091 Digital Flow Meter with back-run stop is used to determine the amount of water passing through a plankton net or a pipe. The back-run stop mechanism ensures the counter only records flow during upward or retrieval movement—ideal for vertical hauls. It features a 5-digit counter, a 70 mm propeller, and a 32 mm counter body. The unit’s free-flooding design allows operation at unlimited oceanographic depths. Water volume can be calculated using KC Denmark’s conversion spreadsheet for circular, square, or rectangular net shapes.
