J-Tech gas flow meter

 

J-Tech Leak gas flow meter

Product features:

The J-TEC in-line flow meters provide all the advantages of vortex shedding technology, in a design that is perfect for rugged applications with minimal space requirements. The VF563 Series is the best value for your low-pressure gaseous flow applications. This device is the meter of choice especially for the measurement of blow-by gases in engine testing applications. Other vortex flow meters lack crucial sensitivity because they can only detect vortices created by large, restrictive obstructions. This diminishes important low-end performance. 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 flow meters have no moving parts, so they are rugged and trouble-free.


Benefits include:

Minimal effect on engine performance during measurement, low pressure drop, driftfree performance, excellent at low flows (down to 0.14 ACFM), easy maintenance, 40:1 turndown ratio, continuous flow readings, high accuracy, excellent repeatability.
