Weathermatic – 1 1/2” Flow Sensor Tee – SLFSI-T15

SLFSI-T10

1 1/2” Tee 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

• Threaded retaining nut makes it easier to service in a valve box
• The molded mounting tee provides consistent measurements and overall improved performance
• Four bladed lightweight impeller is sensitive enough to measure lower flow rates
• Smart electronics capable of better signal filtering
• Affordable enough to install on nearly all new and old systems
