Sliding Waveguide On Anaerobic Digesters - Siemens Sitrans LR200 Instruction Manual

Sliding Waveguide on Anaerobic Digesters

Notes:
• Minimum distance from the flange face to the target is limited by Near Range (2.8. 1 .).
• We recommend adjusting Auto False Echo Suppression parameters with an empty
or almost empty vessel.
This application is to obtain a level measurement and corresponding 4 to 20 mA output
proportional to the sludge level on a digester.

• The raised position is for installation
and maintenance.
• The lowered position is for operation.
• Program the instrument for operation
in the lowered position.
• Low Cal. Pt. is the bottom of the
digester (10 m/33 ft from sensor
reference point when the instrument
is lowered to its normal operating
position).
• High Cal.Pt. is 2 m (6.56 ft) from sensor
reference point.
• The maximum rate of filling or
emptying is about 0. 1 m (4")/min.
