ABSTRACT:
Method for momentarily identifying the composition of a gas or fluid flow, and device for carrying out the method.
The flow is conducted through an orifice in a conduit. Parallel to--and passing over--the orifice, there is a capillary conduit having a mass-flow meter therein. There is measured a combination of physical properties. By comparing said combination with values from a table, each of which is associated with a specific gas composition, the current composition may be determined.
