A.1.4
Volume
①
Main fill level for full calibration. Above this
level erroneous readings will result as level
has entered blanking zone.
⑦
Span: Corresponds to tank manufac-
turer's empty level
②
'Alternate'
⑧
Rise
③
'Preferred'
⑨
Tank manufacturer's empty level
④
'Bad'
⑩
Discharge
⑤
Tank manufacturer's full level
⑪
May require target to obtain empty
reading
⑥
Beam angle
⑫
Empty level for 'alternate' locations.
Below this level, echo would reflect
away from the transducer.
Notes:
1.
Beam should not detect bin bottom.
If this occurs, use range extension parameters (on transceivers where available) to omit
false echoes.
2.
Sound beam must be perpendicular to liquid surface.
When mounting the standpipe and flange, you must ensure that the transducer face will
be parallel with the liquid's surface. Refer to Standpipes (Page 38).
