    What to do if Endress+Hauser Measuring Instruments shows 'FLOW LIMIT' error?
    • K
      Kiara Vincent DDSAug 8, 2025
      If the Endress+Hauser Measuring Instruments indicates a 'FLOW LIMIT' error, it means the measured flow has exceeded the maximum limit. To resolve this, either reduce the flow rate or replace the instrument with one that is appropriately sized for your application.

    What to do if Endress+Hauser Measuring Instruments displays 'RANGE PULSE' error?
    • L
      Laura Fields PhDAug 18, 2025
      If the Endress+Hauser Measuring Instruments displays a 'RANGE PULSE' error, it indicates that the pulse output frequency is outside the set range. You can resolve this by increasing the pulse value, reducing the flow, or choosing a pulse width value that can be processed by any connected counter.

    Why does my Endress+Hauser Measuring Instruments show 'RANGE CUR.OUT' error, and how to fix it?
    • J
      Jennifer MartinAug 29, 2025
      If the Endress+Hauser Measuring Instruments displays a 'RANGE CUR.OUT' error, it means the actual flow value is outside the set limits. To fix this, change the full-scale value entered or reduce the flow.
