Horizontal Vessel With Volume Measurement - Siemens SITRANS LR250 Operating Instructions Manual

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 status of BAD or UNCERTAIN
after 120 seconds (2 minutes).
