Spanish, French and German. 3.2.2 Dosing The Flowmax 242i can be configured for manually dosing by choosing the dosing function via the user display. The Volume “Dosing Quantity“ and the “Dosing Time“ are freely adjustable. The dosing time is intended as a safeguard against unintentional overspill. -
Page 17: Media
In the sub menu “Set Offset” it is possible to set the actual offset of the flow meter. Use this function only when Flowmax 242i is completely filled with liquid, and there is no flow. If the offset is set while flow is present or when the pipe is empty it will cause an offset drift what results in a faulty measurement. -
Page 18: Basic Trim
3.2.3.4 Basic Trim The “Basic Trim” function insures that the flowmeter is conforming to the media NOTICE! specific characteristics. To execute this function, Flowmax 242i runs a self- diagnostic function which optimizes all important parameters. This process lasts approximately 1 minute. -

Page 20: Lower Limit
The pulse value determines the flow volumes for which an output pulse will be emitted. Choose a configuration which will neither exceed the maximum output frequency of the Flowmax 242i (10kHz) nor the maximum input frequency of the control. If the maximum frequency is exceeded the Flowmax 242i will not output pulses correctly. -
