7 Commissioning
CAUTION
Risk of burns due to hot measuring media
The device surface temperature may exceed 70 °C (158 °F),
depending on the measuring medium temperature!
•
Before starting work on the device, make sure that it has
cooled sufficiently.
During commissioning of the flowmeter, observe the following
points:
•
The ambient and operating conditions (pressure,
temperature, power supply) must correspond to the
details on the name plate and the specifications.
•
Open the shut-off valves slowly to prevent pressure
surges that can damage the flowmeter.
•
For liquid measurement media, vent the piping if
necessary.
•
For devices with alarm signalling units, set the units to
the required switching points.
Adjusting the alarm signalling unit
The alarm signalling unit is designed as a proximity switch. When
inserted in the proximity switch, the metal tag initiates the
switching process. The switching point can be adjusted with a
screwdriver.

1. Unscrew the housing cover.
2. Adjust the alarm setting to the required switching point
using a flat-bladed screwdriver.
3. Screw on housing cover.
Operating instructions
If there is a chance that safe operation is no longer possible,
take the device out of operation and secure it against
unintended startup.
