Dwyer Instruments

Dwyer Instruments, Inc. produces a broad range of competitively priced precision instruments for measuring, transmitting and controlling pressure, temperature, level and flow. Many of these instruments are widely known by their individual brand names, such as Magnehelic® and Spirahelic® pressure gages, Photohelic® switch/gages, Rate-Master®, Mini-Master® and Visi-Float® flowmeters, Slack-Tube® and Flex-Tube® manometers, and Dwyer® pressure switches.

Other established Dwyer brands, including Flotect® flow and level switches, Hi-Flow® valves, Self-tune® temperature controllers and Iso-Verter® signal converters/isolators, are the products of companies that are now divisions of Dwyer Instruments--Mercoid, W.E. Anderson, Proximity Controls and Love Controls.

Dwyer's recent product acquisitions include Dickson's MinigraphTM strip chart recorder, ABB Kent-Taylor's Hi-Flow® valves and Quick-Scan® recorders and controllers. Another recent addition is a complete line of butterfly valves.

Founded in 1931, Dwyer Instruments moved its manufacturing and headquarters from Chicago, Illinois, in 1955, to newly constructed, greatly-expanded facilities in Michigan City, Indiana. The company has since added four more Indiana facilities--in Wakarusa, South Whitley, Kingsbury and Wolcott--as well as manufacturing facilities in Anaheim, California; Fergus Falls, Minnesota; Kansas City, Missouri; and Naguabo, Puerto Rico.

In addition to making and selling quality precision instruments, Dwyer is committed to a standard of customer service--including competitive prices and knowledgeable, courteous technical support--that generates and sustains long-term relationships.
