The OS-1-M Optical Level Sensor V2 is equipped with a magnetic mount and is designed for reliable long-term performance. It connects directly to the FMM (Flexible Module Management) system, allowing for effective monitoring of water levels in sumps, mixing stations, or other reservoirs with walls up to 1/4" thick. The sensor uses reflected infrared light to detect changes in water levels, making it suitable for applications like auto top-off systems and high-level warnings. Each unit includes an optical sensor and magnetic mount, but requires the FMM module for operation.
