General Description
The DOR series insertion paddle wheel flow
sensor is a very cost effective means of
accurately measuring the flow of water or
water-like liquids in large pipes. The sensor
is inserted into the process piping via a
threadolet 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 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 and batch
controllers.
