Flow Switches
Model No: KCPL-FSS Series
Flow Switches are designed to monitor the presence or absence of liquid flow in pipelines and provide a switching signal for alarm, pump protection, interlocking or control applications.
A paddle or vane installed in the flow stream operates the internal microswitch when the flow reaches the set point. The switching point can be adjusted using the set-point screw, while interchangeable paddles allow the same flow switch to be adapted for different pipeline sizes.
Available with weatherproof or flameproof enclosures and multiple process connection options, the Flow Switch is suitable for industrial cooling water, utility lines, process pipelines and equipment protection applications.
