Horizontal vessel with volume measurement

Notes:
• Minimum distance from flange face to target is limited by Near Range (2.8.1.).
• We recommend using Auto False Echo Suppression with an empty or almost empty
vessel.
To obtain level measurement/4 to 20 mA output 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 LR200 is to go into Fail-safe High after 2 minutes.
