FSM4000 ELECTROMAGNETIC FLOWMETER | OI/FSM4000-EN REV. E 53
8 Operation
Safety instructions
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.
Aggressive or corrosive media may lead to the damage of
wetted parts of the sensor. As a result, measuring medium under
pressure can leak out.
Wear to the flange gasket or process connection gaskets
(e.g. pipe fitting, Tri-clamp, etc.) may caused a pressurized
measuring medium to escape.
When using internal flat gaskets, they can become brittle
through CIP- / SIP processes.
If pressure surges above the permissible nominal pressure of the
device occur permanently during operation, this may affect the
service life of the device.
If there is a chance that safe operation is no longer possible,
take the device out of operation and secure it against
unintended startup.
Display options
After switching on the power supply, the current process
information for the measuring point is displayed.
In the first line of the display, the current flow direction (
→
F for
forward,
←
R for reverse) is displayed along with the flowrate
as a percentage or a physical unit. The second line of the display
shows the totalizer value (7-digit) for the current flow direction,
followed by the relevant unit.
Independent of the pulse factor, the totalizer value is always the
current flowrate with relevant unit. This indicator is displayed in
the following text as process information.
The 4 lines of the display can be customized in the ‘Display’
submenu.
Examples:
→
V 98.14 l/h 1. line Current upstream flow rate
→
V 12.30000 m
3
2. line Totalizer value, forward
←
R 516.0000 m
3
3. line Totalizer value, reverse (multiplex
mode)
Totalizer overflow always occurs at a value of 9,999,999 units. If
the totalizer value for a flow direction is larger than 9,999,999
units, Warning 9 is displayed in the 4th line. The totalizer
software can register up to 250 overflows. The overflow
notification can be cleared in the Totalizer submenu by using the
‘Reset totalizer’ function.
