Metrological
security
Metrological security protects the transmitter from all changes that
would affect measurement. This includes changes to configuration and
some maintenance procedures.
Micro Motion implements metrological security via “software security.”
Software security is a setting inside the transmitter that
programmatically disables the prohibited actions. Software security can
be enabled or disabled from ProLink III. Practically speaking, software
security provides complete protection against unauthorized changes or
actions.
Physical
security
Physical security is implemented by a seal installed by a certified
Weights & Measures inspector. The seal prevents access to the service
port terminals.
Although the seal can be broken easily, it cannot be replaced by
anybody other than a Weights & Measures inspector. This makes it easy
to detect that security has been violated. If the seal is not intact,
transmitter measurements are not valid for custody transfer.
Configuration methods
You must use ProLink III and a service port connection to configure the Weights &
Measures parameters.
8.2
Set up the Weights & Measures application
using ProLink III
When your transmitter is set up to comply with OIML or NTEP requirements, and the
transmitter is secured, selected measurement data from the transmitter is approved for
Weights & Measures applications.
Prerequisites
Important
Review the Weights & Measures requirements for your location and ensure that you are complying
with all local requirements as well as the OIML or NTEP requirements.
If necessary for your installation, arrange for a site visit by a certified Weights & Measures
inspector, and ensure that the inspector is present for the appropriate portions of this
procedure.
Create the physical setup for the wire seal that will be installed by the Weights & Measures
inspector.
Ensure that the transmitter is ready to be secured, i.e., it is configured as desired and you
have performed all appropriate tests and adjustments. After the transmitter is secured,
you cannot make any changes to configuration, many maintenance actions are disallowed,
and some operator actions are disallowed.
Set up the Weights & Measures application
