Horizontal vessel with volume measurement
Note
The minimum distance from the flange face to the target is limited 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 user-defined value of 4.5 m (14.76
ft) after 2 minutes.
