Two-phase steam measurement system
First Claim
1. A steam measurement system comprising:
- a Coriolis flowtube to receive a flow of wet steam, wherein a bulk density of the flow is determined based on a motion of the Coriolis flowtube;
a sensor to determine a property of the flow of wet steam; and
a computing device to calculate a steam quality of the flow from the bulk density and the property.

Abstract
A steam measurement system includes a Coriolis flowmeter associated with a vibratable flowtube to receive a flow of wet steam. A first sensor is associated with the flowtube to relay information about a motion of the flowtube by way of a first sensor signal. A second sensor determines a property of the flow and relays the property by way of a second sensor signal. A computing device receives the first and second sensor signals and is configured to calculate a steam quality of the flow from the first and second sensor signals. The computing device also may calculate the total heat energy flow rate of the flow. Other implementations may include a full or partial separator to separate the flow of wet steam into a substantially gas flow and a substantially liquid flow and a second Coriolis meter.
