WFS / Liquid Flow Switch, 1-8″ Pipe, Brass 1″ conn. SS paddle, 5-100degC, contact 15amp, 250vac

WFS Flow Switch

The WFS Flow Switch  monitors liquid movement in your piping systems. It ensures that your pumps and chillers operate safely at all times. This device prevents expensive equipment damage by detecting flow failure instantly. It is a vital safety component for any liquid cooling or heating process.

Key Features of the WFS Flow Switch

The unit uses a high-capacity SPDT contact rated at 10A and 250VAC. This powerful switch allows you to control pumps or trigger remote alarms directly. It features an impressive contact cycle rating of 500,000 operations. This long lifespan significantly reduces your maintenance and replacement costs. The internal screw terminals make the electrical wiring process simple and secure for installers.

Rugged Materials and High Durability

This switch uses premium stainless steel paddles for maximum corrosion resistance. These paddles withstand the constant force of moving liquid without bending. The medium connection features a heavy-duty 1” NPT brass fitting. It handles a standard working pressure of 1.0Mpa and a maximum pressure of 1.6Mpa safely.

Wide Temperature Versatility

The switch operates reliably in medium temperatures ranging from 5°C to 100°C. This wide range makes it suitable for both chilled water and hot water lines. A durable ABS cover protects the internal steel body from dust and debris. The unit performs best in ambient environment temperatures between 5°C and 50°C. It offers steady, mechanical performance in demanding mechanical rooms.

Common Industrial Applications

Many engineers install the WFS Flow Switch in commercial HVAC and chiller systems. It detects if water is moving through the heat exchanger properly. If the flow stops, the switch cuts power to prevent the system from freezing. This simple safety step saves thousands of dollars in potential repair costs. It works perfectly for liquid lines in factories, malls, and office buildings. Choosing this mechanical switch ensures peace of mind for your facility management team.
