Water Meter Constants
The water meters' ratio
– defines
the amount of water represented by
each pulse of the water meter.
8.6
Fertilizer Sites Constants
When pulses fail to arrive
– Fertilizer
injectors equipped with fertilizer meters
are expected to supply pulses when
activated. If no pulses arrive within 2
minutes from activation, (4 minutes if the
ratio is 10 L/pulse) then the system will
declare a fertilizer failure and will react
according to the selected action:
Stop faulty injector
– continue fertilization with the other fertilizers
Stop fertigation
– stop all fertilizers of the Fert. Site but continue irrigation
Stop irrigation
– both irrigation and fertilization will stop
Inform only
– report the problem but continue as usual
The Fert. meter's ratio
– defines the
amount of fertilizer represented by each
pulse of the fertilizer meter.
The pulse length
– defines the length of
the pulses which will be used when
fertilizing
proportionally
sec/min
or
m:s/m3. If for example the required
proportion will be 20 sec/min the system
will inject each minute 4 pulses of 5
seconds with 10 seconds between the
pulses.
