The DOR series insertion paddle wheel fl ow sensor is a very cost effective instrument for accurately measuring the fl ow of water or water-like liquids in large pipes.

The sensor is inserted into the process piping via a thread-o- let or half nipple fi tting. Liquid fl ow through the pipe results in rotation of the affi xed paddle wheel. The rotational speed of the paddle is proportional to the fl ow velocity, and therefore, proportional to the fl owrate in the pipe.

The insertion type design provides a measuring technique that is much less expensive than full bore fl owmeters, especially in larger pipe sizes. Insertion paddle wheel sensors are a robust measuring technology that boasts exceptional tolerance to dirt and solids.

The DOR series features an all 316 L stainless steel body. The rotor is made of PVDF or PEEK, with a long-life graphite/ PTFE self-lubricating bearing. The DOR has an integral, precision insertion mechanism that allows the installer to insert the rotor to the precise depth in the pipe for optimal readings.

Outputs include NPN open collector frequency, and/or reed contact frequency or millivolt frequency. Optional indicators include battery powered totalizers, loop powered ratemeter/ totalizers with outputs and batch controllers.

The DOR-5 is suitable for "hot tap" installation. With its sym- metrical design, the DOR may also be used for bi-directional flow measurement.
