Symptom Cause Action
Reads correctly but
occasionally reads
high when vessel is
not full
• detecting close range echo
• build up near top of tank or
nozzle
• water or other high ε
r
material in antenna threads
• wrong antenna choice for
application
• stand pipe problem
• increase blanking
• increase confidence
threshold P804
• rod extensions may be
required
• See Application Example:
Stillpipe on page 53
• material is within near
blanking zone
• tank near empty and low ε
r
material
• multiple echoes processed
• decrease blanking P800 (min.
0.4 m)
• raise IQ 300
• decrease range extension
• install still pipe deflector
(contact Milltronics)
• set P820 to ‘6’
• Standpipe too narrow for
length
• See Rod Extension
Requirements on page 26
Level reading lower
than material level
• Internal seam in standpipe • Inspect and remove seam
Maintenance
The IQ Radar 300 requires no maintenance or cleaning under normal operating
conditions.
Note: Under severe operating conditions, the antenna may require periodic cleaning.
