Using the data logger

Prosonic Flow has the capability to log volume flow, flow velocity, sound velocity, signal strength,
signal to noise ratio, the content of the three internal totalizers, external volume flow, and the actual
current of the current input. The data set is fixed and not configurable. The sampling time is
configurable. The logged data are stored on an external memory unit (1 GB USB memory stick) in
a CSV text format.
Logging is started from the LOGGING function found in the OUTPUTS F DATA LOGGER
menu when a memory stick is available. Logging is stopped in the same function or by removing the
memory stick from the unit. The latter is not a recommended method due to the remote possibility
corrupting the data.

Data exchange with Prosonic Flow 93T

Prosonic Flow 93T uses a text file format commonly referred to as a CSV format (Comma Separated
Values) for its data exchange.
A logged data record is placed on one line. A record contains a number of fields (time stamp,
measurement parameters, flow data, etc.). A delimiter – a blank space, semi-colon, comma or other
character that indicates the beginning or end of a field – is used to organize the fields into columns.
A separator – usually a point (.) or a comma (,) – is used to identify the location of the decimal.
The Prosonic Flow 93T can be configured to record logs using different characters assigned as
decimal separator and field delimiter.  ä 99 The settings required are dependant on the local
settings used by the PCs and Laptops in a particular region.
