Electronics compartment
The compartment on the front has a cover with a glass window. It contains a frame with a
number of printed circuit boards. The boards have the following functions:
• Frequency and status output board
• Processor boards
• Sensor driver board
• Display module (connected tot the front side of the frame, can be seen through the cover with
the glass window)
2.3 Software description
The ALTOSONIC V12 contains a powerful microprocessor that controls the functions and
calculations it performs. The microprocessor executes program code consisting of several
modules, according to the functions it has to perform. By means of a set of parameters the
software can be configured to various sizes and models of flowmeters and according to specific
requirements depending of applications or customers.
Individual parameters are classified according to “roles” in order to define differentiated access
rights. Each “role” is associated with a “typical” user or operator having specific responsibilities
or duties. Users have to be registered with a user name and a password, when registered the
role of the user is also defined, and by consequence also the access rights of that user.
The following roles have been defined, listed in according to the rank in the hierarchy.
Roles and authorisation
Only a higher rank user can register a lower rank user. Users can have the same rank.
In addition to restrictions depending of the defined role of a user, a physical “overwrite disable”
contact / jumper protects the configuration parameters. This disables any user from making
modifications to parameters that would influence the measured flow or volume value. This
prevents unintentional or unauthorized changes to the parameters and possibly invalidation of
the calibration.
LEGAL NOTICE!
The parameters are stored in a configuration file. Configuration parameters are password
protected in order to prevent unauthorized modification. Access in order to read, view and
inspect parameter values is unrestricted.
Developer restricted to KROHNE R&D employees.
Factory restricted to KROHNE factory employees, to implement factory settings in the
meter.
Service restricted to authorized service personnel, to the discretion of KROHNE.
Calibrator restricted to personnel acting on behalf of a legal calibration station.
Supervisor restricted to personnel acting on behalf of the owner/operator of
the meter (administrator function), to the discretion of the owner/operator of the
meter.
Operator restricted to personnel acting on behalf of the owner/ operator of the meter (for day
to day operation), to the discretion of the owner/operator of the meter.
