PRODUCT DETAILS


SLFSI-T20 - 2'' Tee (Slip) Type Insert Flow Sensor Used with the SmartLink Flow Aircard

  • Detect leaks, broken heads, lateral and main line breaks
  • User defined low/high flow limits, by zone
  • Automatic shutdown of both master and/or zone valve when flow limits are exceeded

 

Features

  • Molded Mounting Tee for improved control of dimensions for more consistent measurement and improved performance at low flow.
  • Threaded Retaining Nut instead of retaining pin makes it easier to service in a valve box, more moisture resistance for electronics resulting in longer life.
  • Unique 4 bladed lightweight impeller measures lower flow rates. Detects flow as low as 20% of published minimum rate of other impeller sensors
  • Smart electronics detection system contains a micro-processor for better signal filtering and conditioning. Detection circuit also contains superior over-voltage and overcurrent protection.
  • Affordable enough to install on nearly all new and old systems.
