Measurement Status Measurement Status messages that may appear on the Integral Display, on
the 375 Handheld Communicator, in DeltaV, or in RRM are shown in
Table 7-7:
Table 7-7. Measurement status.
Message Description Action
Full tank The level measurement is in Full Tank
state. The transmitter waits for the surface
echo to be detected at the top of the tank. No action needed.
Empty tank The level measurement is in Empty Tank
state. The transmitter waits for the surface
echo to be detected at the bottom of the
tank. No action needed.
Probe missing Probe is not detected. Check that the probe is correctly
mounted. Check the connection between
probe and transmitter head.
Seal contaminated Suspected contamination of the seal has
been detected. Check if the seal connection with the
probe is contaminated.
Reference pulse calculated The position of the reference pulse is
calculated from the internal reference
pulse. No action needed.
Reference pulse invalid An error in the reference pulse in the last
sampled tank signal. Check Warning messages. If MicroWave
Module (MWM) Warning is active, this
might indicate a transmitter error. Contact
Emerson Process Management Service
Department.
DeltaF not at setpoint The DeltaF is not correctly regulated. Check Warning Messages. If MicroWave
Module (MWM) Warning is active, this
might indicate a transmitter error. Contact
Emerson Process Management Service
Department.
Tank signal clip warning The last Tank Signal was clipped. Check Warning Messages. If MWM
Warning is active, this might indicate a
transmitter error. Contact Emerson
Process Management Service
Department.
No surface echo found The Surface Echo Pulse cannot be
detected.
Possible cause:
• Wrong surface threshold
• Liquid level in Transition Zone or
below probe end
Check if the configuration can be
changed so that the surface echo can be
tracked in this current region.
View the Echo Curve plot and check
surface threshold.
Predicted level The presented level is predicted. The
surface echo could not be detected. Check if the configuration can be
changed so that the surface echo can be
tracked in this current region.
View the Echo Curve plot and check
surface threshold.
No reference echo The Surface Echo Pulse cannot be
detected. Check if the configuration can be
changed so that the surface echo can be
tracked in this current region.
Reduced reference echo The reference echo has been found with
reduced amplitude. No action needed.
In full tank state The level measurement is in the full tank
state, waiting for a surface echo detection
at the top of the tank. No action needed.
Sampling failed The sampling of the last tank signal failed. Check Warning Messages.
Invalid volume value The given volume value is invalid. The
given measurements are simulated. Check Volume Status for details.
