Harwil Q-4 Flow Switch
Harwil® type Q-4 industrial flow switches are designed for extreme, long-term reliability, and for use in particle contaminated fluids. They detect and signal flow change and remain continuously adjustable while in operation. Four individual paddle options plus continuous adjustment provide a wide operating range. They maintain calibration limits when subjected to reasonable line hydraulic hammer or surge pulses. A DPDT model is available upon request.
