16.1.1 SONTEX NOWA.EXE V1.03
16.1.1.1 Key data
Manufacturer abbr.: SON
Type of meter:
Integrator Supercal: SUPERCAL, SUPERCAL531 or SC
Volume measuring part: SUPERSTATIC or SS440
Supported NOWA-test modes: V, RKS, RTS, TK,TT
Adjustment options: V
Parallel capability
(With the respective Nowamux-hardware): Yes
Special features:
To ensure a reliable communication, it is necessary to know if optical probes are used with or with-
out echo.
Unless further specified, the programme assumes that optical probes with echo are used. In case
optical probes without echo are used, the line ‚NoMirror’ (without inverted commas!) has to be
added to the text file „SON\Options.cfg“ (see point 3).
To calibrate the meter correctly, the meter has to be opened. Therefore two internal jumpers (cali-
bration seal) are plugged in the integrator upper part and the test jumpers are plugged in the lower
part.
16.1.1.2 Test and calibration procedure
General information on the test and the calibration:
For each meter, the important test points for the calibration are stated in a file in clear-text format.
The files are in the sub-folder with the name of the meter: SON\SC531\...
This file name is made up as follows:
File name = „Qp in l/h“ with the file extensions
’.PRF’ for files with test points for the verification and
’.ABG’ for the files with test points for the adjustment.
Example: ’SON\SC531\2500.ABG’ resp. ’ SON\SC531\2500.PRF’
The test points are filed line by line acc. to the NOWA-convention (indexes for the different pa-
rameters).
The diverse measuring methods are identified by the special programme-internal code number
’10.03’ (see annotated example: ’1500.ABG’).
Checking of a test cycle for its suitability as adjustment reference point:
The following parameters are (depending on the measuring method) compared with the set values
of the calibration data file:
Test mode V:
Qmin-measurement: min. measurement duration: 120s
Current flow range: 0..5% Qp
Qp-measurement: max. error: 10% of current meter setting
Min. measurement duration: 90s
Max. deviation current flow: -50% / +10%
The effective CURRENT values which are sent by the test rig at least once during the test cycle
are used for the comparison.
