The Heavy Duty Truflo UFS Series flow switch is easy to install and offers excellent chemical resistance and reliability. The UFS Series is available with a normally open or normally closed reed switch contact. The nominal switching point is determined by the length of the paddle. During installation, the paddle is typically cut at a mark based upon the pipe diameter, equating to the highest possible switch sensitivity and lowest switching point. Installation is easy; simply insert the UFS Flow Switch into an appropriately sized Tee fitting.
