The CST FSI-T15-001 is a wired impeller flow sensor engineered for inline installation in a 1-1/2 inch molded PVC tee. It combines a unique 4-bladed lightweight impeller with processor-based "Smart Electronics" to deliver a stable square-wave digital signal proportional to flow. The output duplicates common impeller sensor characteristics, allowing straightforward integration with existing controllers and monitoring systems.

  • Secure PVC tee mounting: Molded 1-1/2 in. tee provides a reliable, inline mounting point for the sensor.
  • Threaded retaining nut: Keeps the impeller housing firmly seated for consistent performance.
  • Responsive impeller design: Four-blade, lightweight impeller reduces inertia and improves responsiveness to flow changes.
  • Smart Electronics: Processor-based detection and conditioning produce clean square-wave pulses suitable for controller inputs.
  • Long-distance signal: Pulse output will transmit up to 2,000 feet without amplification under typical wiring.

Ideal for irrigation, pump monitoring and general fluid-handling applications, the FSI-T15-001 offers low-maintenance operation and straightforward wiring. Install the sensor in the molded tee oriented to flow, tighten the threaded retaining nut to seat the impeller housing, and verify pulse output at the controller input before commissioning. For system-specific wiring or controller compatibility questions, consult your controller documentation or technical support.
