NOTE!
The protection class of the control unit is only ensured if the connection ports are protected by caps or the
standard connectors are inserted.
8.2 Flow rate setting
The flow rate is defined by two parameters:
1. Volumetric displacement per dosing stroke
The stroke length adjustment limits the movement of the diaphragm. Adjusting the stroke length does not
have a linear proportional effect on the stroke volume. The volume per dosing stroke is derived from the
delivery characteristic curves or the delivery table on the dosing pump.
To adjust, undo the lock screw, set the required value and retighten the lock screw.
ATTENTION!
Do not adjust stroke length while the pump is stationary but rather only during the delivery stroke.
2. Stroke frequency
Changing the stroke frequency has a directly proportional effect on the flow rate. It is either set to a fixed
value or defined by an external pulse generator (e.g. electronic controller or contact water meter).
To ensure effective adaptation of the dosing pump to the respective process, the MAGDOS can be set to
different stroke frequencies in internal mode.
