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/4 to 20 mA output proportional to resin levels:
• Low Calibration Pt. = 5 m (16.5 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:
