Application with stillpipe

Note
• Near Range (2.8.1.) (Blanking) will be set at the factory. Check the process connection
tag for specific values.
• Suitable pipe diameters are 40 mm (1.5") to 100 mm (4").
• The pipe diameter must be matched with the antenna size. Use the largest antenna size
that will fit the stillpipe/bypass pipe. See Dimensions (Page 183).
• See Mounting on a Stillpipe or Bypass Pipe (Page 32) for installation guidelines.
This application is to obtain a level measurement and corresponding 4 to 20 mA output
proportional to the oil level in a fuel storage vessel.
● Low Calibration Pt. is 5 m (16.5 ft) from the sensor reference point.
● High Calibration Pt. is 0.5 m (1.65 ft) from the sensor reference point.
● The stillpipe inside diameter is 50 mm (1.96").
● The maximum rate of filling or emptying is about 0.1 m (4")/min.
