The device is maintenance-free, however, a periodic inspection according pertinent
directives and regulations must be carried out.
An inspection can include check of:
● Ambient conditions
● Seal integrity of the process connections, cable entries, and cover screws
● Reliability of power supply, lightning protection, and grounds
Under ideal conditions the flowmeter will operate continuously with no manual adjustment or
intervention required.
The SITRANS F M Verificator is an external tool developed for verifying the MAG 5000/6000
system, installation, and application. It is a highly advanced instrument, which carries out the
complex verification of the entire flowmeter system according to unique SIEMENS patented
principles. The verification test is automated and the instrument easy to use, so no human
error or influence will affect the verification.
9.1 Transmitter check list
If unstable/wrong measurements occur, it is often due to insufficient/wrong earthing or
potential equalization. If earthing connection is OK, check transmitter as described below,
and sensor as described in sensor check lists (see the respective operating instructions).
The easiest way to check the transmitter in a SITRANS F M installation is to replace the
transmitter with another MAG 5000/6000 with a similar power supply.
As all settings are stored in and downloaded from the SENSORPROM
®
, replacement is
easily done and no extra settings need to be made.
