Flowmax 242i Assembly and installation When using pumps, Flowmax 242i must be installed in flow direction on the pressure side, on order to ensure sufficient pressure. The maximum pressure rating of Flowmax 242i has to be considered. Do not exceed the maximum pressure allowance for of the Flowmax 242i (see section 5.2 Technical specifications). -
Page 8: Figure 4: Mounting Possibilities
Vibrations or mechanical forces may decrease measuring accuracy. So if there is due to vibration or mechanical movements it is necessary to fix Flowmax 242i additionally, the instrument can be fixed on the lateral slot. Figure 5: Fixing Flowmax 242i Flowmax 242i must be installed without mechanical tensions on the existing pipe system. -

3 Seconds 3.2.3 Media Flowmax 242i comes with a medium matrix with up to 8 interpolation values. Different media can be managed in the sub menu “Media”. By using the sub menu point “Correction” it is possible to correct the flow measurement in percent. -
Page 16: Basic Trim
3.2.6 Basic Trim The “Basic Trim” function insures that the flow meter 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 17: Units
4,2s 3.2.8 Units Flowmax 242i is able to show actual flow or the volume in different units. Following units can be selected: ml/s + l , Gal/min +Gal , l/min + l , l/min + m³. The first letters correspond to the unit of the flow value. The letters after the + correspond to the unit of the volume value. -
Page 18: Analog Output Qa
Commissioning Flowmax 242i 3.2.11 Analog output QA The analog output is available as current output 4-20mA or 0-20mA. This is selected with the purchase order. As a standard it comes with current output 4- 20mA. It can also be switched off by the device menu. The current output ranges from 0 to 22.6mA measuring the flow rate or the condition of the flow measurement. -
Page 19: Pulse Value
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. -
