1.5. Calibration

The µ-FLOW and LIQUI-FLOW are factory calibrated. Periodical inspection, recalibration or verification of the accuracy
may be subject to individual requirements of the end user.
Bronkhorst certifies that the instrument meets the rated accuracy. Calibration has been performed using measurement
standards traceable to the Dutch Metrology Institute (VSL).

1.6. Maintenance

The µ-FLOW and LIQUI-FLOW needs no regular maintenance if operated properly, with clean media, compatible with
the wetted materials, avoiding pressure and thermal shocks and vibrations. Units may be purged with a clean, dry and
inert gas.
In case of severe contamination, cleaning the inside of the device may be required. After cleaning, recalibration of the
instrument is recommended.
Inexpertly servicing instruments can lead to serious personal injury and/or damage to the instrument or
the system it is used in. Servicing must therefore be performed by trained and qualified personnel.
Contact your Bronkhorst representative for information about cleaning and calibration. Bronkhorst has
a trained staff available.

1.7. Documentation

The µ-FLOW and LIQUI-FLOW come with all necessary documentation for basic operation and maintenance. Some parts
of this manual refer to other documents, most of which can be downloaded from the Bronkhorst website. Calibration
certificates, test certificates and material certificates are included in the scope of delivery or can be provided on request.
