(4) Data Format
Detail format output from DIGITAL port 1 is as follows,
[Sample Data]
$,F,0.000,0.000,,,,E+3:m3/h,0.000,m/s,0000000,x1m3,,,,,,ROFF,R1,,,,,OVER,,,,,ITG,*06[CR][LF]
Data output from UFL-20A are referred to as a line of data interchange. Data items in each line
are contained in data FIELDs which are numbered, for example "field 0", "field 1" and so on until it
ends at "field 28". Each data FIELD contains a single data VARIABLE. The order of data
FIELDs on each line is defined by a data HEADING "$", with the rest of the data line written in
[CR][LF] code. The data field HEADINGs and data VARIABLEs on each line are separated by
commas.
Empty data FIELDS are enclosed by double quotes, ",,,,".
The applicable FIELDs of data are as follows,

2 Flow volume
Flow velocity (in case of velocity mode)
Result of average flow volume or flow velocity from each path.
Main unit parameters determine numerical digits and decimal
fractions.
Any compensation settings are included in this result.

3 Flow volume of path no.1
Flow velocity of path no.1 (in case of velocity mode) Same as field 2
4 Flow volume of path no.2
Flow velocity of path no.2 (in case of velocity mode) Same as field 2
5 Flow volume of path no.3
Flow velocity of path no.3 (in case of velocity mode) Same as field 2
6 Flow volume of path no.4
Flow velocity of path no.4 (in case of velocity mode) Same as field 2
7 Measuring Unit for flow rate
This unit is set by main unit parameters.
Double quotes ":" will be inserted between exponential
indicators and measurement units.
If the exponential indicators are set as x1, double quotes ":"
are omitted and only units are indicated.
m3/h
m3/min
E+3:m3/h
E-3:L/s
m/s
ft/s
8 Velocity
During flowmeter operation mode, this value is calculated from
flow volume.
During velocity operation mode, this value is calculated from
measured velocity with all compensation parameters such as
"zero shift", "span correction" and "low-cut" functions added.
Decimal fraction is fixed at 3 digits.
This value will be the same as field No.2 in case of velocity
mode.
