Counting with grading machines

The PLC is widely used when fish are graded. The scanner is mounted either on the grader or at the end of the pipes leading from the grader to each pen.

Counting results are displayed on the control unit, and up to four scanners can be connected and running simultaneously. The control unit can be set to ring a loud alarm bell when it has counted a particular number of fish. Flanges to fit various graders can be made to measure, so that the counter can be used in a wide variety of situations.

Counting with fish pump

The PLC can easily count directly from fish pumps and can handle high continuous water flow.

PC Computer Interface

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
