It must be maintained both minimum time and
minimum pulse quantities.
4) After the simulation of flow measured volume
V (m

(or through a digital interface) or calculated
pulse counter calculates the volume pulse

3. Calibration instruction
3.1.1 Calibration mode
To enter calibration mode it is necessary to
connect the verification jumper 1, remove
metrological seal and short circuit calibration
contacts 2. (Fig.2).
3.2 Software installation
The software “SonoMeter30Config.exe” is used
to read and configure SonoMeter 30 device via
OG-1-USB optical reader.
Meter configuration / calibration cab be made
also via M-Bus interface module then converter
COM/M-Bus (MB-1) can be used.
Open “SonoMeter30Config.exe”. Press “Next”.
Then, you can choose installation directory.
“SonoMeter30UserConfig” has five user interface
windows for different purposes:
• “Actual” – actual data window;
• “LCD Menu” – LCD configuration window.
• “Configuration” – configuration window for
pulse channels, archive and tariffs;
3.3 Program interface
• “Archive” – window for information from
device archive;
• “Manufacturer” – device calibration, reset and
configuration window.
