Accusonic 8510+ series Reference Manual page 55

When necessary a numeric index will follow the letter designation if there is more than one file of that

type.
The file extension will be "CSV".

As an example the file 01042012 P5.csv indicates:
The date of the first record in the file is January 4 2012.

The file contains path data: sound velocity, gain, gain %... see below.

The numeric index of 5 indicates this data is for path 5

The Data Files
There are 7 different data file categories that can be generated during the collection process. They are:
Q files, where n indicates flow section 1 to 4 and the data consists of Date Stamp, Section

n
Section level data
n
T files, where the n indicates flow section and the data consists of Date stamp, Section

n
Section Temperature data
n
P files where the n indicates path number and the data consists of;

n
Date Stamp,Path
Path envelope fwd time in microseconds, Path
n
Path zero-crossing fwd time in microseconds, Path
n
Path travel time differential in nanoseconds, note this can be envelope or zero-crossing and depends
n
on the actual detection method used for this path when this record was saved
V files, the data consists of the Date Stamp, Path1 velocity data, ...Path 10 velocity data

S files, the data consists of the Date Stamp, Total flow data for the meter, total volume data for the

meter
L files, the data consists of Date Stamp, Level channel 1 to 4 level data, Level channel 1 to 4 raw data

E files, the data consists of Date Stamp, Path status word, Section status word, level status word

Note: The 8510+ flowmeter writes a .csv file daily and can be opened with any version of Microsoft
Each column will have the data variable labels in the top row located directly above the raw data. Accuflow is
not necessary for viewing or downloading data from the 8510+ flowmeter.
