FSW-160 Series Paddle Flow Switch

The FSW-160 series heavy-duty flow switches from Omega Engineering are designed to provide reliable control in critical applications where flow monitoring is essential. It signals, starts, or stops electronically operated equipment when flow or no-flow conditions occur, making it ideal for a variety of industrial environments. Unlike traditional metal bellows, which can suffer from fatigue and corrosion, the FSW-160 uses an advanced elastomeric-sealing system that has been field-proven for over a decade, offering superior durability and performance. The switch is compatible with pipes as small as 1" and as large as 48", with setpoints ranging from 4 GPM to over 500 GPM. It features a robust SPDT micro switch capable of controlling a 1/2 horsepower motor. It operates under a maximum working pressure of 200 psig, with negligible pressure drops in larger pipe sizes. Designed with high-quality materials such as brass, 304 and 316 stainless steel, and EPDM seals, it ensures long-lasting performance in demanding environments, withstanding temperatures up to +121°C (+250°F).
