Enhance the reliability of your IntelliChem Chemical Controller system with this specialized External Flow Switch Kit. Featuring a 3-foot cable length, this kit is specifically designed for both commercial and residential applications where the original equipment flow switch may be experiencing performance issues. The kit excels in low flow applications, making it an ideal solution for systems that operate with minimal water movement. Compatible with Pentair IntelliChem systems (part numbers 522622, 522621, and Commercial Systems), this flow switch ensures accurate chemical control monitoring. The durable construction includes a clear housing for visual confirmation of operation and professional-grade wiring for lasting performance. This US-manufactured component comes complete with all necessary mounting hardware and is ready for installation. The robust design helps maintain consistent chemical controller operation, particularly in challenging low-flow environments where standard switches might falter.
