SITRANS LR250 (FOUNDATION FIELDBUS)
58 Operating Instructions, 01/2014, A5E32221411-AB
6.2.2
Horizontal vessel with volume measurement
Note
The minimum distance from the flange face to the target is lim
ited by
Near Range (2.5.1.)
.
To obtain level measurement proportional to vessel volume in a chemical vessel:
● Low Calibration Point = 3.5 m (11.48 ft) from sensor reference point
● High Calibration Point = 0.5 m (1.64 ft) from sensor reference point
● Max. fill/empty rate = 0.2 m/min (0.65 ft/min)
● Select vessel shape, Parabolic Ends, and enter values for A and L, to obtain a volume
reading instead of level.
In the event of a loss of echo:
● SITRANS LR250 is to report a status of BAD or UNCERTAIN after 120 seconds (2 minutes).
