Harwil Q-5/Q-5SS Flow Switch

Harwil^® type Q-5 & Q-5SS industrial flow switches are designed for extreme, long-term reliability, and for use in particle contaminated fluids. Multiple quick change paddles and continuous spring adjustment provide an incredibly wide operating range of flow rates and viscosities. They are calibrated independent of line pressure and temperature, and maintain calibration limits when subjected to reasonable line hydraulic hammer or surge pulses. A DPDT model is available upon request.
