Abstract
A method and apparatus for determining the quality of steam and steam flow rate use the thrust or impact force of the steam against a device in the steam flow path and restriction data from a choke or orifice plate. The impact force can be read from a variety of devices mounted in the steam flow path and using known electrical and/or mechanical reading and recording techniques. The restriction data can be derived from measurements taken across known flow restriction devices such as an orifice plate or a choke.
