flow update By Jesse Yoder Ph D Considering Variable Area Flowmeters A Device with a Fascinating Past Potentially a Bright Future W hile variable area VA flowmeters are limited in their functionality they cost far less than most other types of flowmeters When users are looking for a simple low cost solution VA meters are a particularly good fit While they can measure flowrate they are well suited for applications where a flow no flow determination is desired They are also very effective at measuring low flowrates and since they do not require electric power they can safely be used in flammable environments History The history of variable area meters dates to 1908 when they were invented by German engineer Karl Kueppers in Aachen Germany At that Shipments of Variable Area Gas Flowmeters by Region in 2010 170 43 44 time they were called rotameters named after the rotating float that was originally a component of these meters Felix Meyer recognized the commercial potential of Kueppers 325 49 31 338 North America Europe Mideast Africa Japan China Rest of Asia Latin America Source The World Market for Gas Flow Measurement 2nd Edition Published by Flow Research in June 2011 invention and in 1909 founded Deutsche Rotawerke in Aachen The product invented by Karl Kueppers was the first variable area flowmeter with a rotating float The German company Deutsche Rotawerke was the forerunner of the company that became known as the Rota Company Originally Meyer called his products rotamesser In 1995 Yokogawa yokogawa com purchased the Rota Company and named the resulting company Rota Yokogawa Rota Yokogawa yokogawa com rota de still manufactures its variable area meters which it also calls rotameters in Wehr Germany In the meantime the GEC Crawley Company in Crawley United Kingdom began manufacturing the first glass variable area meters and registered the name Rotameter as a trademark in the United Kingdom This name still exists as a trademark in the United Kingdom but has been passed down through a number of companies including KDG Instruments and Solartron Mobrey mobrey com In March 2009 Emerson Process Management emersonprocess com acquired Solartron Mobrey presumably for its level density and flow computer products As part of the acquisition Emerson Process acquired the trademark to the name rotameter in the United Kingdom Max Flow Meters Dont let our competitors lead time put your project on hold You already have a flow metering problem you dont need a supplier delivery problem as well So call A flow measurement company you can count on Max Machinery Inc maxmachinery com an ISO 9001 2008 certified company T 7074332662 26 January 2012 Flow Control
