Operating princip
The proportioning dosing injector is fitted on the water line. The flow of water passing through the
injector activates it and causes the pumping of liquid fertilizer (or other additive) and inject it in a
relative quantity into the water line.
The MixRite TF 25 technical working range:
The flow rate of water passing through the injector is between 3 and 25 m³/Hr. (9 – 110 GPM).
The water pressure is between 1 and 8 bar (14.7 and 120 PSI).
The water and air temperatures are not less than 4°C and not more than 40°C (39°F - 104°F).
Head loss: Low flow 0.2 Bar – High flow 1.5 Bar.
Max deviation injection rate +/- 10%.
Before using, an initial calibration should be done, in order to assure accurate match with the
injector printed scale.

the range of:
0.1% to 1%
0.2% to 2.5%
0.5% to 5.5%
