Communication protocol specific

The DOAP over NFC is a secure protocol defined by ABB
between the Velox Interface App and the transmitter, based
upon a secret device identification pin hand shake.
The Modbus protocol is an unsecured protocol, as such the
network security risk for the intended application should be
assessed to ensure that these protocols are suitable before
implementation.
The FTPS protocol runs on 4G variant of the transmitter is a
secure protocol based on TLS1.2 with digital certificate based
mutual authentication.
The LwM2M/CoAP over DTLS-PSK protocol runs on NB variant
of the transmitter is an unsecured protocol, as such the
intended application should be assessed to ensure that these
protocols are suitable before implementation.
Intended use
This flowmeter is intended for the following uses:
• To transmit fluid media with electrical conductivity.
• To measure and compute flow rate, flow velocity, volume
flow (forward, reverse and net) and pressure (option).
The flowmeter has been designed for use exclusively within the
technical limit values indicated on the identification plate and
in the data sheets.
In terms of the measuring medium, observe the following
points:
• Wetted parts such as measuring electrodes, liner,
grounding electrodes, grounding rings, protection flanges
must not be damaged because of the chemical and physical
characteristic of the measuring medium.
• The information on the name plate must be observed.

Improper use

The following are considered to be instances of improper use of
the flowmeter:
• For operating as a flexible adapter in piping, for example.
for compensating pipe offsets, pipe vibrations, pipe
expansions.
• For use as a climbing aid, e.g. for mounting purposes.
• For use as a support for external loads, e.g. as a support for
piping, etc.
• Material application, e.g. by painting over the name plate or
welding/soldering on parts.
• Material removal, e.g. by spot drilling the housing.
