Liquid Resin In Storage Vessel, Level Measurement - Siemens SITRANS LR250 PROFIBUS PA Operating Instructions Manual

6.2.1

Liquid resin in storage vessel, level measurement

Note
Minimum distance from flange face to target is limited by Near Range (2.5.1.).
To obtain level measurement proportional to resin levels:
● Low Calibration Pt. = 5 m (16.4 ft) from sensor reference point
● High Calibration Pt.= 0.5 m (1.64 ft) from sensor reference point
● Max.fill/empty rate = 0.2 m/min (0.65 ft/min)
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.
