FEATURES

• Designed for service in metallic piping systems at points of connection or on pump assemblies.
• Custom designed brass bodied tee for improved control of dimensions for more consistent measurement and improved performance at low flow.
• Brass 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.
