sfe-flow-rate

Matlab functions to read and analyse flow-rate data from a Coriolis flow-meter.

getAvgFlowrate.m (command line function)

Calculates the average flowrate from the SFE equipment flowrate file.

Run from the command window as:

getAvgFlowrate(filename)

or

getAvgFlowrate(filename, target)

• filename is a string of the flowrate file (without .txt extention)
• target is the value of the desired flowrate. If target is provided the desired value will be drawn on the graph (optional parameter).

monitorAvgFlowrate.m (command line function)

Automatically monitors the flowrate by calculating the average value every 60 seconds. Ctrl+C to stop.

Run from the command window as:

monitorAvgFlowrate(filename)

or

monitorAvgFlowrate(filename, target)

• filename is a string of the flowrate file (without .txt extention).
• target is the value of the desired flowrate. If target is provided the desired value will be drawn on the graph (optional parameter).

cossolvent.m (command line function)

Calculates the cossolvent flowrate in ml/min for a given cossolvent mass fraction

Run from the command window as:

cossolvent(Q_CO2, x_cossolvent)

or

cossolvent(Q_CO2, x_cossolvent, cossolvent)

• Q_CO2 is the CO2 flowrate in g/min
• x_cossolvent is the cossolvent mass fraction
• cossolvent is a string representing the cossolvent. Currently, only ethanol is supported. Default is ethanol.

flowratesAnalysis.m (script)

Script to run through all flow-rate files in the specified folders and report time and average flow-rates.
