Menu 3.4.3 Nozzle size flow at 45 psi
In fault free operation, the controller uses the flow sensor and the
pressure sensor to detect the nozzle size.
In case of flow sensor and/or pressure sensor fault, the nozzle flow can
be entered to obtain a more accurate regulation of the regulation valve.
If either the flow sensor or the pressure sensor is faulty, the nozzle
cannot be identified. The controller stores the last detected nozzle size,
and this value is then used.
•
Default value: 0.21 gpm (0.80 l/min)
˜
ATTENTION! If changing nozzles while a sensor is faulty, then type
in the size of the new nozzle.
Nozzle size is defined as flow at 3 bar as to be seen in the Hardi® nozzle catalog.
÷
NOTE! The flow at 45 psi in the Hardi® nozzle catalog is measured without nozzle filter and without Pentalet nozzle
holder. The flow restriction from these 2 make the nozzle appear smaller, see table below.
Menu 3.4.4 Dual line second nozzle (not used in North America)
