Description

The FCS-01 flow switch utilizes a reliable reed switch mechanism activated by a magnet attached to a shuttle, which moves in response to fluid flow. This design provides a simple, robust, and contactless method for detecting the presence or absence of flow in a pipe, with minimal pressure drop. The switch is normally open (NO) and closes upon reaching the specified flow threshold.

Engineered for durability, the sensor features a Noryl housing and stainless steel spring, making it resistant to corrosion and suitable for use with potable water and air. Its wide operating temperature and pressure range allow for deployment in diverse environments, from cooling systems and circulation pumps to leak detection and mains water control applications.

Key Features

  • Reliable Reed Switch: Features a ruthenium contact reed switch (file E125629) for long-life, low-power switching.
  • Low-Flow Sensitivity: Activates at a minimal flow rate of 0.6 liters per minute, ideal for protection and monitoring.
  • Robust Mechanical Construction: Noryl housing and stainless steel internal components ensure corrosion resistance and longevity.
  • Versatile Media Compatibility: Suitable for sensing flow of both water (hot/cold potable) and air.
  • Environmental Durability: Rated for operation from -25°C to 85°C and withstands vibration (35g up to 500Hz) and shock (50g for 11ms).
  • Easy Integration: Standard 3/8" BSP male threads facilitate straightforward installation into existing piping.
  • Safety Certified: Housing carries a UL94-HB flammability rating.

Applications

  • Circulation Pump Protection: Detects flow failure in heating or cooling loops to prevent pump dry-running and overheating.
  • Leak Detection Systems: Monitors for unexpected flow in supply lines to trigger alarms or shut-off valves.
  • Mains Water Control: Used in automated water dispensing, filtration systems, or irrigation to confirm flow before/after a valve.
  • Cooling System Monitoring: Ensures adequate coolant flow in industrial machinery, CNC equipment, or server racks.
  • Process Flow Verification: Provides a simple on/off signal for flow presence in chemical dosing, beverage dispensing, or air handling units.

Frequently Asked Questions

What is the electrical rating of the reed switch in the FCS-01?

The integrated SPST-NO (Normally Open) reed switch is rated for a maximum switching voltage of 200 VDC or 250 VAC, with a maximum current of 1 Amp and a load of 40 Watts. It provides a simple dry contact closure when the flow threshold is reached.

At what flow rate does this switch activate?

The FCS-01 flow switch is designed to actuate (close the reed switch contacts) when the flow rate reaches 0.6 liters per minute. This low threshold makes it suitable for detecting minimal flow for pump protection or leak detection applications.

What fluids and conditions is this flow sensor compatible with?

It is compatible with water (including hot and cold potable water) and air. The Noryl housing and food-grade material make it suitable for many applications. It operates within a temperature range of -25°C to 85°C and can withstand a maximum pressure of 10 Bar at 20°C.

How do I install the FCS-01 flow switch?

Installation is straightforward via its 3/8" British Standard Pipe (BSP) male threaded ports. Simply thread it inline into your piping. The sensor can be mounted in any orientation (any axis) without affecting its performance.
