2.1 Principles of operation
Figure 2-1: Diagram showing the basic operation of the FertiMiX-Go!.
9
2.2 Process description
The FertiMiX works as follows:
Fresh water is supplied (optionally pre-blended with drain water).
The supply pipe is fitted with:
(optionally) a filter for filtering water,
(if the pre-pressure is less than two bars) a filling pump for pumping
water into the mixing tank,
(optional) an EC sensor for pre-blending control.
The water flows into the mixing tank via the filling module. The filling module
regulates the water supply to the mixing tank.
The system pump pumps the water from the mixing tank towards the pressure
module.
From the pressure module, the water is directed to the dosing module.
Some of the water flows to the measurement module. The measurement
module is a branch line where the EC and/or pH is measured.
A dosing module consists of one or more dosing channels. Each fertilizer (or
other additive) requires its own dosing channel equipped with a venturi.
Fertilizers (or other additives) are sucked out of the stock tanks connected to
the venturis.
The fertilizers and other additives are dosed using the dosing valves based on
the fertigation recipe.
From the dosing module and measurement module, the water is fed into the
mixing tank.
The design of the supply pipe creates a swirling motion in the mixing tank. This
swirling motion effectively mixes and aerates the water and fertilizers. This
ensures that the fertilizers dissolve completely and allows the equilibrium
reaction of the acid or alkali (lye) with the water to stabilize. This reaction
creates CO2 gas. The residence time of the water inside the mixing tank plays a
key role in the mixing process. It also allows the CO2 gas to escape from the
mixture, preventing gas bubbles from clogging the pipes.
A float and valve prevent the mixing tank from overflowing.
Once the water and fertilizers have been mixed sufficiently, the system pump
pumps the irrigation water from the mixing tank to the pressure module. This
module has a branch line for distributing the irrigation water.
The water flows to the irrigation valves and is then supplied to the crop. If
required, the water can first be filtered and the flow rate can be measured.
FertiMiX
10
The entire process is controlled by the HortiMaX-Go! process controller. Its tasks
include:
ensuring that the correct fertigation recipe is prepared (proportion of fertilizers
and water),
controlling the valves to ensure that the water reaches the crop.

2.3.3 Pressure module with filter
The pressure module is located directly after the connection point of the irrigation
water distribution pipe. The pressure module guides some of the irrigation water to
the dosing module with the measurement module. The pressure module is equipped
with a pressure regulator that enables the pressure before the venturis (see section
"Dosing module" on page15) to be set to 2.2 bars. The pressure after the venturis is
always 0 bars. The screen filter in the pressure module prevents the venturis from
clogging.

Depending on the configuration, the following sensors can be added:
EC sensor: the EC sensor measures the concentration of fertilizers in the water.
pH sensor: the pH sensor measures the acidity level of the water.
The FertiMiX-Go! is supplied with at least one EC sensor as standard.
If there is one EC / pH sensor: this is the control sensor.
If two EC / pH sensors are present: the verification sensor checks the
functioning of the control sensor.
Please consult the supplied OEM manuals for the correct use and maintenance of the
relevant components.
2.3.5 Dosing module
A dosing module consists of one or more dosing channels. Each fertilizer has its own
dosing channel (a maximum of four). The last channel is used to dose acid or alkali
(lye). This is optional.
Before the water reaches the dosing module, some of the water flows past the
measurement module. This is where the EC and/or pH level is measured. See
"Measurement module (sensors)" on the previous page for more information.

More information about using and setting up the irrigation program can be found in
the section "Assigning valves to valve groups" on page46.
5.4 Calibrating the sensors
The sensors need to be checked regularly in order to ensure accurate measurements.
This must be done at least once per year. If the measurements taken by the
verification sensor deviate from those of the control sensor, you need to calibrate the
sensors.
The calibration process requires special calibration solutions. To calibrate an EC
sensor, you will need EC 1.4 and EC 5.0 solutions. To calibrate a pH sensor, you will
need pH 7.0 and 4.0 solutions. The order in which the solutions need to be used is
fixed and may not be reversed.
40
When calibrating the pH sensor: Check whether the water is acidified based
on alkali (lye) or acid. The default setting is based on acid.
5.4.1 Calibration steps
The calibration process involves a few simple steps; the controller will describe the
steps that you need to carry out.
Make sure that you have a bucket of clean tap water to hand.
Navigate the path for the sensor that you want to calibrate.
Calibrate EC sensor: .
Calibrate pH sensor: .
Before taking each measurement, rinse the sensor with the clean tap water and dry it
off gently. Blow away any residual moisture.
Make sure to keep stirring the sensor during the wait time. This ensures that the
solution will remain homogeneous.
The measured values are not displayed during the calibration process,
because the values are still fluctuating. A readout will, however, appear in the
step between the two calibration solutions. This readout may differ slightly
from the final value, because the calibration process is not yet complete.

can change the EC, pH and volume settings of the valve group. Do not forget
to change the settings back afterwards. An alternative method is to assign the
desired valves to a group that is still 'free'. You can program different recipe
settings for this group without changing your standard recipes.
Preprogramming start conditions
FertiMiX
The irrigation program includes a number of start conditions that can be preset or
preprogrammed:
Cyclic
start
A cyclic start applies for a specific period and valve group.
