Oil field ground wet steam flow dryness measuring device

The invention discloses an oil field ground wet steam flow dryness measuring device and relates to a device for measuring gas-liquid two-phase mixed fluid data such as the flow. The oil field ground wet steam flow dryness measuring device solves the problems that existing devices used for measuring parameters such as pressure, flow and dryness of wet saturated steam used for oil field steam injection are low in measuring precision, poor in accuracy, large in size and the like in practical usage. The oil field ground wet steam flow dryness measuring device comprises a flow divider, a separator and a measuring mechanism; the flow divider is connected with an inlet of the separator; the measuring mechanism is provided with measuring components in an outlet pipeline of the separator; the flow divider is a multipoint multistage flow dividing device. The oil field ground wet steam flow dryness measuring device has the advantages of being small in weight and size, compact in structure, easy to manufacture, convenient to maintain and use, high in measuring precision, being mainly used for measuring relative parameters of the gas-liquid two-phase mixed fluids used for oil fields and the like.
