11.6 Dosing Channel Configuration
• Pump: Select the type of dosing pump:

Venturi: The dosing unit consists of Venturi driven injectors. The dosing booster will be turned on when
fertigation is active (refer to the following section Analog Output Card Calibration with Dosing Machine).

Hydraulic: The dosing unit consists of hydraulic fertilizer pumps. The dosing booster is not needed and
will not be turned on when Fertigation is active. When working with hydraulic pump, the method can
only be Liter/Pulse and EC & pH control is not possible.

Electric: The dosing unit consists of electrical fertilizer pumps. The dosing booster is not needed and
will not be turned on when Fertigation is active.

Analog: This dosing unit consists of pumps controlled by 4 – 20 mA analog output. Define the analog
outputs in Analog Output Definition, page 42.
• Method: Select the operating method:

Liter/Pulse: Define whether a dosing meter is connected to this channel and used for control purposes.
Set the volume per pulse on the Ratio column.

Time (cc/sec): Define whether the calculated flow rate of the dosing channel is in CC (gallons) of
fertilizer per second.

Time (Liter/min): Define whether the calculated flow rate of the dosing channel is in liters (gallons) per
minute.

Time (Liter/Hour): Define whether the calculated flow rate of the dosing channel is in liters (gallons) per
Hour (default option).
• Ratio

Method is Time: Define calculated flow rate, this will be the flow rate of the channel when completely
open.

Method is Liter/Pulse: Define the volume per pulse.
• React: Set the required use of the channel:

EC: The channel is used to increase measured EC, meaning it will be opened more when the measured
EC is lower than the set EC.

pH: The channel is used to decrease measured pH, meaning it will be opened more when the
measured pH is higher than the set pH.
