Application With Stillpipe - Siemens Sitrans LR200 Instruction Manual

Application with Stillpipe

A stillpipe is recommended for products with a dK of less than 3, or if extremely turbulent or
vortex conditions exist. This mounting arrangement can also be used to provide optimum
signal conditions on foaming materials.
Notes:
• Near Range (2.8.1.) (Blanking) will be set at the factory. Check the Process Device Tag for
specific values.
• Suitable pipe diameters are 40 mm (1.5") to 100 mm (4").
• The pipe diameter must be matched with the horn size. Use the largest horn size that will
fit the stillpipe/bypass pipe (see
Mounting on a Stillpipe or Bypass Pipe
• See
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.
