Lorric FP-AS510 Paddlewheel Flowmeter

The FP-AS510 has a measuring range that doubles that of other brands, which allows for the detection of any disappearance of the paddle which tends to cause zero-flow problems, on top of large indicator lights and a large screen that allows for more convenient on-site supervision.


  • LORRIC exclusive patent - The AxleSense Technology
  • Exclusive LCD/LED double screen design, double screen monitoring which makes work
    equivalent to 1+1>2
  • Green, yellow and red indicator lights: Red – Major abnormality; Green – Normal operation;
    Yellow – Non-urgent data display.
  • Daily Accumulation of positive/negative/net flow volume in the past 14 days
  • The screen can change direction according to the pipes’ alignment.
  • Bidirectional flow detectable
