DPS300 System Integration • Assemble the transducer to the Siemens Skimmer Guard if provided. Otherwise install directly to your conduit with a ¾” to 1” NPT or BSP reducer. Refer to the Skimmer Guard section for dimension and assembly details. Refer to the XCT-12 manual for connection and wiring details only.
Most circular tanks have a catwalk that extends into the centre of the tank, usually with 2" (51 mm) or similar, tubular railings. These railings are the recommended mounting location for the InterRanger™. The Siemens Mounting Assembly is available to locate the transducer in this location. Inlet This is where the wastewater flows into the tank.
Page 17
In circular tanks, the skimmer and scraper are often connected to the same rotating mechanism radiating from the centre of the tank. Common configurations could include one or two skimmers and up to four scrapers. Usually these arms are 90° or 180° apart. 7ML19981BC01 InterRanger DPS300...

In rectangular tanks, often the scrapers are also the skimmers. They run along the bottom on a chain mechanism for the length of the tank, up the side and then along the top to pull the scum into a trough. 7ML19981BC01 InterRanger DPS300...

Mounting Assembly Usage In clarifiers where skimmers are in use, the transducer must be raised to avoid damage from the passing skimmer. If you have a Siemens Skimmer Guard, refer to that manual before installing the Mounting Assembly. Refer to the DPS300 system manual to determine the appropriate location for installing the Mounting Assembly.
