When the mixed phase fluid passes through the device main body 101, workers do not need to sample the mixed phase fluid, so that the labor and time consumption are reduced, and the cost is reduced.
It should be noted that, in order to protect the devices in the online metering computer 104 from external physical damage, the meter chamber 107 needs to be additionally installed externally.
The device body 101 is hollow 108, the shuttle 106 is in the hollow 201, and one end of the device body 101 is connected with a pipeline 105 of an oil and gas well.
