The multi-EC controller is an automatic feed dosing unit capable of feeding from two fertilizer stock solutions. The controller can be used in combination with an automatic Sprinkler for irrigation through solenoid valves.
The controller is easy to operate and has the following features:

• EC measurement in the discharge pipe
• EC control down to 0.1 mS
• Controller switched on via signal from a pump or contact switch.
• Accurate fertilizer dosage through pulses to control valve (24 V AC)

In addition, the meter can be fitted with a second EC meter. The first EC measurement is the raw water and the second measurement is the addition of feed from the stock tanks.
Feed from the A and B stock tanks is monitored:

• Equal dosing from both tanks
• Level sensors fitted on two tanks
• Minimum level alarm

There is a digital read out of EC and tank levels.
In an alarm situation, the automatic Sprinkler is stopped, according to the following criteria:

• Too high EC
• Too low EC
• Too large a difference between A and B tank levels
• Too high water temperature

The controller can be linked to a PC (option)
