  • Harwil Q-8N/Q-8CR Flow Switch

    Harwil® type Q-8N & Q-8CR industrial flow switches are designed for long-term reliability and chemical resistance. They detect and signal flow change and remain continuously adjustable while in operation. Particle contamination resistance is provided by a single convolute elastomeric seal which is continually flushed by working fluid flow.

  • Kobold FPS Flow Switch

    Kobold® type FPS paddle-bellows flow switches are used wherever reliable control for minimum or maximum liquid flow is required. The interchangeable paddles, in conjunction with an external adjustment screw, allow for adjustment over a wide range of switching points and easy adaptation of the flow switch to different pipe sizes. The internals of the instrument are separated from the process by the bellows, making it an excellent choice for dirty media. The FPS-6 Series is a special design variation used when lower switching points are desirable.
