Engine Blow-By

 

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. The VF563 is the flowmeter of choice for measurement of crankcase blowby gases in engine emissions testing applications. Measuring the flow rate of blow-by gases as they flow out of the crankcase vent is an effective way to monitor piston-ring sealing, lubricant performance, and crankcase ventilation systems. The J-TEC design incorporates a small strut, which offers minimal flow restriction, for high accuracy over an extended range.  Each meter is individually calibrated to NIST traceable standards.  J-TEC blow-by flow meters have no moving parts, so they are rugged and trouble-free. 

Benefits include:  Minimal effect on engine performance during blow by measurement, low pressure drop, drift-free performance, excellent at low flows (down to 0.14 ACFM), easy maintenance, 40:1 turndown ratio, continuous flow readings, high accuracy, and excellent repeatability.
