Description

The DOR series insertion paddle wheel flow sensor is a very cost effective instrument for accurately measuring the flow 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 fitting. Liquid flow through the pipe results in rotation of the affixed paddle wheel. The rotational speed of the paddle is proportional to the flow velocity, and therefore, proportional to the flowrate in the pipe.

The insertion type design provides a measuring technique that is much less expensive than full bore flowmeters, 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 316L 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. Optional indicators include battery powered totalizers, loop powered ratemeter/totalizers and batch controllers. The DOR-5 is suitable for "hot tap" installation. With its symmetrical design the DOR may be used for bi-directional flow measurement.
