Transducer Ringing
If the transducer is mounted too tightly, or if it is mounted so that its side touches
something (such as a vessel wall, or standpipe), its resonance characteristics change
and this can cause problems. Hand tighten only. PTFE tape is not recommended as it
reduces friction resulting in a tighter connection that can lead to ringing.
Normal Ring Down
Poor Ring Down
Ring down times that extend past the near range area can be interpreted by the SITRANS
LUT400 as the material level and are characterized by a steady high level being reported.
Echo Profile Display
To assist in troubleshooting echo profiles, pan and zoom options are available. See
“Requesting an Echo Profile” on page 57.
Trend Display
A trend display is available with pan and zoom options. See “Trends” on page 118.
