Low Calibration Pt. (2.3.7.1.)
Distance from sensor reference point to Low Calibration Point (corresponding to Low Level
Point). Units are defined in Unit (2.3.1.).
① High level point (default 100%) ⑥ Level offset (if used)
② Low level point (0%) ⑦ Low calibration point
③ Sensor value ⑧ Sensor reference point
a)
④ High calibration point ⑨ Far range
⑤ Level
a)
The point from which level measurement is referenced [see Flat Faced Flange (Page 227)
and Threaded Horn Antenna with extension (Page 191) and Flanged encapsulated antenna
(3"/DN80/80A sizes and larger). (Page 202) ].
Values Range: 0.00 to 20.00 m. Default 20.00 m
Related parameters Unit (2.3.1.)
Far Range (2.5.2.)
High Calibration Point (2.3.7.2.)
Distance from sensor reference point
1)
to High Calibration Point (corresponding to High Level
Point). Units are defined in Unit (2.3.1.). See Low Calibration Point (2.3.7.1.) for an
illustration.
Values Range: 0.00 to 20.00 m. Default 0.00 m
Related parameters Unit (2.3.1.), Near Range (2.5.1.)
When setting the High Calibration Point value, note that echoes are ignored within Near
Range (2.5.1.).
1)
The value produced by the echo processing which represents the distance from sensor
reference point to the target. [see Threaded Horn Antenna with extension, (Page 194)
Flanged Horn with extension (Page 198), and Flanged encapsulated antenna (3"/DN80/80A
sizes and larger) (Page 202)].
