Automatic nutrient dosing system with pH and EC control
Controller with four dosing pumps
A system for preparing and maintaining nutrient solution in a reservoir used for hydroponics or fertigation. Probes measure the solution’s pH, electrical conductivity (EC) and temperature. The controller compares readings with the chosen targets and operates four dosing pumps for three nutrient stock solutions and one pH adjustment solution. Dosing is separated by mixing intervals so readings can stabilize before the next correction. It automates nutrient solution adjustment and integrates with a reservoir, mixing equipment, water supply and irrigation network sized for the installation.
