Weathermatic - 2'' Flow Sensor Tee - SLFSI-T20

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.
