Known flow:
Is used, if the constant is unknown or if flow through flow sensor changed significantly
(replace nozzle inserts with greater or smaller flow). In this case, measure flow capacity of
nozzles at defined pressure. Perform the measurement in the following manner:
Select manual protocol on AG-tronik, open all distribution valves and MAIN valve.
Note: known flow functions only in manual protocol. If the AUTO protocol is on, entry in
window is not possible, X blinks next to the display.
Set pressure to value, set for spraying, e.g. 10 bar. Use gauged flask to measure flow of one
nozzle in one minute. If the nozzles are new, capacity or flow/nozzle can be taken from
enclosed factory flow table. If the measured flow (or recapitulated flow from table) per nozzle
is multiplied by the number of functioning nozzles, we get KNOWN FLOW or total current
flow through flow sensor. It is important that the water flow through sensor during
measurement is similar to liquid flow in the time of spraying. In the moment of measuring, all
the nozzles must have equal flow.
ATTENTION! Flow sensor functions correctly only in the range from 5 to 50 l/min.
Choose the line KNOWN FLOW and press the key
to open new window:
Figure 25 Figure 26
The display shows:
current constant (imp/l)
number of operating nozzles (no. nozzles)
flow/nozzle (flow/n)
common flow through nozzles (flow)
Option of entering following parameters is available:
number of operating nozzles (no. nozzles)
flow/nozzle (flow/n)
common flow through nozzles (flow)
When you open the window KNOWN FLOW, the value in number of nozzles is framed. If you
wish to change the number of nozzles, press key
to choose the line (frame starts to
blink). Set new value with keys
or
and confirm it with key
.
If you wish to change the value in the line flow/nozzle, follow this procedure:
