4.7 Instrument re-ranging
Re-ranging can easily be performed by changing the capacity of the instrument. This can be performed by
using FlowPlot, E-7000 or Bright readout/control module, RS232 digital communication or any available
fieldbus communication interface supporting parameter 21: capacity. Capacity can be set between minimum
capacity and maximum capacity. The actual values depend on the type of instrument.
FlowPlot can be downloaded at: http://downloads.bronkhorst.com
Example of changing flow range using FlowPlot:
Enter max flow range here (capacity) or move the slider.
4.8 Instrument filter settings
Changing filter settings can be done using FlowPlot.
FlowPlot can be downloaded at: http://downloads.bronkhorst.com
Output filter:
Dynamic display factor and Static display factor are filter settings for readout only (at analog output and digital
output). Output signal filtering at stable situation and at a flow-step can be set separately.
Sensor filter:
Exponential smoothing factor is the most important filter parameter to influence the stability of the meter and
will also influence the controller behaviour, where it will be provided as input for the controller.
Adaptive smoothing factor does not have functionality for a mini CORI-FLOW. For a mini CORI-FLOW it will
temporarily switch off the filter during a flow-step to enable fast controller behaviour together with strong
filtering.
For all filter settings:
A value can be entered between 0 and 1, where values close to 0 will filter strongly and slow down the output.
A value close to 1 will speed-up the output and will introduce more noise.
At value = 0, the filter has been switched off. No signal is put-through: no signal changing.
At value = 1, the output is equal to the input: no filtering at all.
