The DFM-2 is a 1.25″ inline digital flow meter that provides accurate measurements of water or nutrient solution flowing through a fluid line. It is specifically designed for the Aqua-X Pro system. When used with the Aqua-X Pro, users can set the irrigation schedule to be controlled “By Volume”, and the DFM-2 will measure and allow the desired, precise amount of nutrient solution to be used. The DFM-2 sensor can also be used for future functionality and may include the ability to detect water leaks and/or line blockages.
