Application Example - Siemens interranger DPS300 Instructional Manual

It is desired to measure the sludge blanket in a circular primary clarifier. The
clarifier is equipped with a skimmer, and the depth of wastewater in the clarifier is
approximately 5 m. When the sludge level rises to about 0.3 m, a pump turns on
to pump out the sludge to a level of about 0.1 m. The pump is then turned off.
Set the following parameters as follows:
System requirements:
•
one DPS300*
•
one XCT-12 transducer
•
one Siemens Skimmer Guard
•
one Siemens Mounting Assembly
*The DPS300 is a dual point monitor, capable of measuring two clarifiers when the
unit is equipped with two transducers. This example shows the unit used for single
point monitoring but two could be used.

Note:
When powered up, the DPS300 will take up to several minutes to lock onto its first
measurement. During this time several errors may be reported. These errors
should be ignored. If errors are reported after the startup period, consult the
Troubleshooting section.
