Apparatus for and method of determining dryness level of steam

An apparatus, for determining a dryness level of steam from a steam source, comprising:

• a flow measurement device for measuring a flow of the steam from the steam source;
• a condenser for producing condensate from the steam from the steam source;
• and
• a condensate sensing device configured to:
• measure a collection value of condensate produced from the steam from the steam source;
• obtain a mass flow rate from the measured flow of the steam from the steam source;
• use the obtained mass flow rate to determine an expected collection value of condensate produced from steam of a known dryness level, or use the obtained mass flow rate to determine an expected collection value of steam from the steam source based on a known dryness level;
• and
• determine a dryness level of the steam from the steam source by comparing a difference between the measured collection value based on the actual measured steam and the expected collection value based on the steam of a known dryness level and thereby determining how much suspended water particles by mass was present in the steam, wherein the measured and expected collection values are the same type of value.
