Notes
• All regulations on the use of meters must be
observed.
• Cavitation in the system must be avoided.
• Meters up to DN25 may only be installed with
directly immersed sensors according to German
calibration law!
• Install the unit in such a way that no water can
enter the electronic unit during operation.
• User seals may only be removed by authorized
persons for service purposes and must be
replaced afterwards.
• The unit is supplied with Installation and Service
Instructions and with Operating Instructions.
• No later than 30 seconds after installation, the
meter detects the plugged modules automatically
and is ready for communication or pulse output.
• The type of modules plugged can be displayed in
the service loop depending on how the display is
parameterized.
• For fast pulses, the parameters must be set
accordingly with the service software.
• Up-to-date versions of all instructions can be
found in the Internet at www.siemens.com/sbt
