ABSTRACT:
A meter measures the quality of steam flowing in a conduit. The steam comprises a liquid and a vapor. The meter includes a mixer in the conduit for mixing the steam in the conduit to produce a mixture which has a density representative of the liquid and the vapor. A density sensor, or desitometer, senses the density of the mixture. The densitomer produces an improved output due to the mixing. A pressure sensor senses pressure in the steam line. A calculating means, such as a microprocessor system, calculates the steam quality as a function of the sensed density and pressure.
