Located in the Heartland community of Cedar Rapids, Iowa, J-TEC Associates has been providing vortex flow meters and sensors for automotive, industrial, military and mining applications since 1968. The company s first development efforts resulted in a technique for measuring ocean currents and an anemometer for the National Data Buoy Program. This invention of a unique and proprietary technology has formed the basis of the principal products of the company, which has led J-TEC into various flow measurement markets. The company s full line of products includes blow-by flow meters, air intake flow meters, exhaust flow meters and emission certification systems. In addition, J-TECs vortex shedding technology produces flow meters with low pressure drops and high turndown ratios, which makes them ideal for the measurement of engine air intake, crankcase blow-by and engine exhaust.
