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
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.
