J-TEC blow-by meters provide all the advantages of vortex shedding flow meters, in a design that is perfect for rugged applications, such as engine dynamometer testing.

  • Our vortex shedding technology produces flow meters with low pressure drop and high turndown ratio, which makes them ideal for measurement of engine air intake, crankcase blow-by and exhaust flows.

  • The patented J-TEC design provides high accuracy and repeatability over an extended flow range. Because the meters have no moving parts, they are rugged, trouble-free and will not wear out.
