Vaki Pipeline Counter (PLC)

The VAKI Pipeline Counter (PLC) is installed in a pipeline from a grading machine or on the end of the pipe into a tank. Most often the PLC is being used for counting fish when being pumped either from a pen to a wellboat when delivering fish for harvesting, or when fish are pumped from one pen to another under grading or splitting of the cages. PLC can also be used at the outlet of a grading machine. The fish are counted as they pass through the counter using infra-red light beams that form a grid inside the scanner. For every fish pumped through the scanner, the grid is broken and an image of the fish is generated. The image is then used to count the fish.
The PLC is also available for Lumpfish.
