COMECO’s PSF100 flow switch is designed to operate with low-viscosity, non-viscous, clean or dirty liquids with moderate flow rates as water and water solutions, oil, and fuels. This model utilizes the well-know principle of thermal dispersion, based on the measurement of temperature difference deviation due to the flow rate via 2 temperature sensors immersed in the controlled medium. An output relay switches when the flow rate reaches the set-point value after a maximum of 15-second response time. An enhanced microcontroller design allows simple user calibration and continuous self-diagnostic.
