Measuring principle
Instruments of the
mini CORI-FLOW
series contain a uniquely shaped, single loop sensor tube, forming part of an
oscillating system. When a fluid flows through the tube, the Coriolis force causes a phase shift, which is detected by sensors
and fed into the integrated printed circuit board. The resulting output signal is proportional to the real mass flow rate,
independent of fluid density, temperature, viscosity, pressure, heat capacity or conductivity. Coriolis mass flow
measurement is fast, accurate and inherently bi-directional. The
mini CORI-FLOW™ M1x
features density and temperature of
the fluid as secondary outputs.
Multi-range
The
mini CORI-FLOW
offers multi-range functionality: factory calibrated ranges can be re-ranged to a different full scale
measuring range (e..g. a mini CORI-FLOW model M13 can be used for full scale ranges between 50 g/h and 2000 g/h). The
analog output and the digital measured value are scaled accordingly.
Switching between ranges can be done via the RS-232 interface or the fieldbus interface, or with a Bronkhorst® readout and
control unit (E-8000, BRIGHT). For RS-232 communication, Bronkhorst can offer a special T-part RS-232 cable to connect the
instrument with a Windows computer, together with free tooling software (FlowPlot). Contact your Bronkhorst
representative for more information.
The instrument comes with a calibration certificate for all supported full scale ranges. The actual full scale of the instrument
is set to a value as ordered and can be found on the instrument label.
Accuracy
The accuracy of a
mini CORI-FLOW
series instrument is either 0.2% reading for liquids or 0.5% reading for gases, 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.

T. Transportation bolts (model M15 only)
Transportation bolts - important notes:
·
Upon delivery, the moving parts of the M15 are immobilized with 2 transportation bolts, to prevent damage to the
sensor during transportation and handling.
·
Before installing the M15, the transportation bolts must be removed.
·
Carefully follow the instructions on the leaflet that is attached to the M15.
·
Do not discard the transportation bolts, but keep them for future use.
·
Before transporting the equipment, (e.g. for relocation or servicing), the transportation bolts must be re-installed.
