CFO Kits

Overview

CFO-200 injects test quantities of propane at a constant flow rate and mixing level. After passing through a ruby orifice, the test gas is injected into the test stream through a rosette. The rosette assures uniform mixing of the test gas before it enters the CVS. Mass is calculated from CFO volume, propane concentration, and density.

More convenient than gravimetric measurements - weighing a gas cylinder before and after injection - the CFO technique provides rapid and accurate results. Portable and rack-mount units are available, with stainless steel tubing used throughout.

Features

Application

CVS Injection Check

Features

  • Eliminates the need to weigh gas cylinders before and after CVS injection test.
  • Meets EPA accuracy standards.
  • Provides immediate measurement of injected gas volume. Mass is determined by multiplying gas volume by gas density.
  • Available in portable and rack-mount configurations.
