Calibrating a Water-Powered Proportional Dilutor

A water-powered proportional dilutor injects a set amount of concentrate into the water passing through it, the concentrate then mixes with the water before the water pressure pushes the solution out of the unit and into the irrigation network. This video focuses on the calibration of the water-powered proportional dilutor or
dosing pump, traditionally used to apply soluble fertilisers
to crops.
