Kaydon and OPW Flow Indicator Manufacturing

Flow Indicator lines, manufactured by Kaydon and OPW Include:

  • Teleflo dial indicators: A rugged design provides a wide range of applications.  Teleflo indicators can be installed in any position in the liquid line.  Teleflo indicators provide electrical liquid flow control protecting thousands of installations against costly equipment damage.

  • Vane Type indicators: Vane Indicators utilize a single observation window and a flow activated vane to furnish a constant readout of liquid flow, clarity and color.  Designed for easy observation of flow indication from either the right, left, up or down.

  • Sight Flow Indicators: Sight Flow Indicators provide a quick, reliable, and economical way to verify flow and monitor color and clarity in fluid lines.  All Kaydon Flow Sight Indicators are equipped with heat-treated glass windows and are constructed of heavy duty cast bronze.  OPW "Visi-Flo" Sight Flow indicators are available in four different types of sight flow.  Bi-Directional (plain) is used when indication of color and/or clarity of the liquid are of prime importance.  Propeller type flow indication is best to show flow of opaque liquids.  Propeller flow indication is also ideal for observations at a distance.  Flapper type flow indication points in either direction to show at a glance which way the liquid is flowing.  Drip Tube flow indication is ideal for gravity, extremely low or intermittent flow.  Keeps liquid from dripping on glass and used in vertical lines only.

Oiler Products include Pressure Oilers and Gravity oilers:

  • Pressure Oilers: A combination of a metering valve and a flow indicator.  It is used for the distributions and supply of oil under pressure to the points of use.  Oiler Features include indication accuracy, indicator ring visible in dark oil, indication of flow rate is not affected by viscosity.

  • Gravity Oilers: The gravity sight feed Oiler affords a clear view and fine control of the oil flow.  Gravity Oiler features include Oiler body vent to prevent fogging, oilers may be manifolded, Oiler bodies made of cast iron construction and maximum working pressure of 125 psi.
