PC Based

An industrial PC can be used to connect up to 4 PLC scanners. The advantages of the PC interface as compared to the normal display unit are numerous.

  • The entire counting session can be recorded for verification later on.
  • Real-time counting results can be viewed with all android and IOS devices.
  • Detailed reports available.
  • Bright display, easily read from a distance.
  • App for all remote control.

Counting Report

A count report is produced automatically after each count.

Each count report includes the total number of fish counted, total counting time, average counting speed (fish/min).

The thru put graph can be used to identify when peaks /maximum throughput in fish/min, and where (if any) overloads occurred.


What our Customers say

“The Pipeline Counter (PLC) has been very useful for us. Especially in the planning process where it is very important for us to know how many fish are in each cage. The PLC has saved us much time and effort and we are very happy with the easy installation and the opportunity to integrate to other equipment on our site”.

“The use of the counters has allowed us to maximize growth and minimize unnecessary stress by transferring the exact number of fish for harvest and leaving the remaining fish to feed and grow”.
