18 PC Logging

The PC Logging tab displays the operation of logging sap flow data direct to a computer. If no logging functions have been selected using the File menu then this tab will simply state that logging is disabled. As with logging data to the MicroSD card of the SFM1 Sap Flow Meter there are two data formats available: Log Incoming Reporting Option Data or Log

Temperatures.

18.1.1 Log Incoming Reporting Option Data

The Log Incoming Reporting Option Data will record the basic parameters; Sap Velocity &

Sap Flow for both Inner & Outer measurement points. Each data point is Date & Time

Stamped and corresponds with the same parameters in the main data file *.CSV as logged to the MicroSD card if one is inserted into the SFM1. If no MicroSD card is inserted then only one file the, the PC_Sapflow.csv will be logged directly to the computer.

Once logging the data file will continue to increase in size as new data is logged at the user defined logging interval via the Measurement Mode drop down menu of the Measurement

Control Section of the SFM software. The Log Incoming Reporting Option Data section of the

PC Logging Tab will keep a live summary of the number of values logged to the file name as chosen by the user. The file name will be displayed complete with the full directory path to ensure the file is easily found.

18.1.1.2 Append Mode

Note that the “Append Mode” can be selected to ensure that if a new logging session is resumed using an existing log file name, a new header will be placed in file at the end of the previous list of records to demarcate subsequent records that are appended to the existing file.

WARNING 20 - Failure to select “Append Mode” without renaming the log file will simply overwrite the contents of the existing log file.
