Critical Flow Orifice Kit

Critical Flow Orifice Kit 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 Critical Flow Orifice Kit volume, propane concentration, and density.

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

Features of Critical Flow Orifice Kit

  1. Eliminates the need to weigh gas cylinders before and after CVS injection test.
  2. Meets EPA accuracy standards.
  3. Provides immediate measurement of injected gas volume. Mass is determined by multiplying gas volume by gas density.
