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.
