Accuracy
The accuracy of a
mini CORI-FLOW
is either 0.2% reading for liquids or 0.5% reading for gases.
This specification is based on mass flow (e.g. g/h, kg/h, etc.). Using the instrument for measuring volume flows (e.g. l/h,
ml/min) will introduce an additional inaccuracy, based on the actual density measured by the instrument. In all instruments
capable of density measurement there will be an automatic adjustment for change in density.
CORI-FILL™
mini CORI-FLOW
instruments with firmware version 1.05g and up are equipped with
CORI-FILL™
technology, designed for
fast and highly accurate mass or volume batch dosing of liquids or gases. The internal batch dosing controller is optimized
for controlling a valve or a (gear) pump, to deliver an exact batch dose, independent of fluid properties, ambient
temperature and back pressure.
1.4
Calibration
The mini CORI-FLOW is factory calibrated. Bronkhorst certifies that the instrument meets the rated accuracy. Calibration is
performed using measurement standards traceable to the Dutch Metrology Institute (VSL). Calibration certificates are
included in the scope of delivery.
Periodical inspection, recalibration or verification of the accuracy may be subject to individual requirements of the end user.
Unless specified otherwise,
mini CORI-FLOW ML120
instruments are H
2
0 calibrated.
1.5
Maintenance
No regular maintenance is required if the mini CORI-FLOW is 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
or a non-aggressive and non-corrosive solvent.
In case of severe contamination, cleaning of the inside of the instrument and of the valve orifice (if applicable) may be
required.
Inexpertly servicing instruments can lead to serious personal injury and/or damage to the instrument or the system it is
used in. Therefore, servicing must be performed by trained and qualified personnel. Contact Bronkhorst for information
about cleaning and calibration. Bronkhorst has a trained staff available.
