摘要： An oil-gas-water three-phase automatic metering device and method includes a liquid inlet pipe, a pump body, a degassing assembly, a water inlet assembly, first and second liquid storage pipes, a weighing assembly, and a control unit. The liquid inlet pipe, degassing assembly, one end of the first liquid storage pipe and one end of the second liquid storage pipe are connected to four valve ports of a first changeover valve, respectively. The water inlet assembly, one end of the pump body, the other end of the first liquid storage pipe, and the other end of the second liquid storage pipe are connected to four valve ports of a second changeover valve, respectively. The degassing assembly, the water inlet assembly and the other end of the pump body are in communication with the weighing assembly, and the pump body, degassing assembly and weighing assembly are communicatively connected to the control unit.
