Erroneous temperature -
measurement
For the temperature compensation
of the measurement variable Qm
a density of 20°C is used, i.e. for a
fluid temperature near 20 °C the
measurements will be correct
The current value is above the
programmed range for current
output 1.
The current value is below the
programmed range for current
output 1
The current value is above the
programmed range for current
output 2.
The current value is below the
programmed range for current
output 2
The measured density of the fluid
in the flowmeter primary is outside
of the specifications
The density of the medium in the
flowmeter primary is < 0.5 kg/l, the
volume totalizers are stopped
The signal from Sensor A is
missing
The signal from Sensor B is
missing
The signal from at least two
sensors is missing
Concentration below 0 % or above
103,125 %.
Parameters cannot be changed
CoriolisMaster FCM2000
Possible Causes
Incorrect wiring
(only for remote design)
Pt 100 is defective
Range setting is too small
Range setting is too small
Range setting is too small
Range setting is too small
This error usually occurs together
with errors 1 and 9.
See errors 1 and 9
The flowmeter primary is not
completely filled with fluid.
Sensor A is defective, or the
amplitude control circuit is open
Sensor B is defective, or the
amplitude control circuit is open
At least two sensors are defective,
or the amplitude control circuit is
open
The measured density or
temperature does not fit in the
given and chosen matrix
The operating protection switch is
active
Error messages
Corrective Measures
Check wiring between flowmeter
primary and converter
Check the resistance of PT100 on
the primary flowmeter
Increase range setting
Increase range setting
Increase range setting
Increase range setting
See errors 1 and 9
Completely fill the flowmeter
primary
Measure resistance of Sensor A
For remote design: Check wiring
between flowmeter primary and
converter
Measure resistance of Sensor B.
For remote design: Check wiring
between flowmeter primary and
converter
Measure resistance of the
sensors.
For remote design: Check wiring
between flowmeter primary and
converter
Correct the chosen matrix
Deactivate the hardware
protection switch.
