What Is the Gems FS-550 Flow Switch?
The Gems FS-550 Flow Switch is a durable, paddle-type flow switch ideal for reliable liquid flow monitoring in piping systems. Built by Gems Sensors & Controls, a known leader in fluid sensing technology, the FS-550 is built for use where accuracy and longevity are critical.
This specific model, 29609, belongs to the FS-550 series more widely known for accommodating diverse flow rates and pressures. The switch is programmed to turn a circuit on or off when liquid flow is at a set point—perfect for those systems needing the immediate response of flow change.
Key Features
Let’s take a closer look at features that make FS-550 model 29609 a go-to flow switch
Rugged Brass Housing: Durable enough to handle harsh industrial and marine conditions, the brass housing resists corrosion and wear.
Paddle Design: Employs a mechanical paddle to sense flow, which activates the switch. A plain but very efficient mechanism.
Field-Adjustable Settings: Provides adjustability for setting the actuation point, making it versatile for a variety of applications.
Durable SPDT Switch: Offers single pole double throw output, allowing compatibility with many system types.
Space Saving and Simple to Install: Directly fits into systems without occupying large space or complex integration.

Applications in Real-World Applications
The Gems FS-550 is engineers’ and maintenance personnel’s favorite due to the fact that it’s not just reliable but also simple to integrate. Some of its most prevalent applications are as follows:
1. Marine Systems
Marine vessels and offshore platforms depend on accurate flow measurement for coolant systems, bilge pumps, and water circulation. The FS-550 keeps those systems running and safe.
2. HVAC Units
The switch supports systems by interrupting pumps when flow is below safety thresholds, avoiding overheating or system harm.
3. Industrial Equipment
From CNC machine cooling lines to manufacturing line lubrication systems, this switch is a fail-safe used to watch and ensure flow integrity.
4. Water Treatment Plants
It is essential that treated water and chemicals flow properly. The FS-550 is ideal for such constant-duty applications.
