Model VF563

In-Line Flow Meter

Product Details

The J-TEC in-line flow meter provides 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.

We can provide the VF563 flow meter as a calibrated system with a handheld display, please see our product page VH563 Hand-Held Blow-By Flow Meter System.

Other vortex in-line 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 of the VF563 in-line flow meter include Minimal effect on engine performance during 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, excellent repeatability.

We can also provide a VF563 Blow By Canister which acts as a buffer that minimizes the effect of engine pulsations and collects oil or mist, while still giving continuous flow readings.
