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:
Message
The level measurement is in Full Tank
state. The transmitter waits for the surface
echo to be detected at the top of the 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.
Probe is not detected.
Suspected contamination of the seal has
been detected.
The position of the reference pulse is
calculated from the internal reference
pulse.
An error in the reference pulse in the last
sampled tank signal.
The DeltaF is not correctly regulated.
The last Tank Signal was clipped.
The Surface Echo Pulse cannot be
detected.
Possible cause:
• Wrong surface threshold
• Liquid level in Transition Zone or
below probe end
The presented level is predicted. The
surface echo could not be detected.
The Surface Echo Pulse cannot be
detected.
The reference echo has been found with
reduced amplitude.
The level measurement is in the full tank
state, waiting for a surface echo detection
at the top of the tank.
The sampling of the last tank signal failed. Check Warning Messages.
The given volume value is invalid. The
given measurements are simulated.
Description
No action needed.
No action needed.
Check that the probe is correctly
mounted. Check the connection between
probe and transmitter head.
Check if the seal connection with the
probe is contaminated.
No action needed.
Check Warning messages. If MicroWave
Module (MWM) Warning is active, this
might indicate a transmitter error. Contact
