Abstract: 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.

Abstract: The method comprises: receiving a first message, and determining that the first message carries a sub-message identifier, the sub-message identifier being used for indicating that the first message is one of several sub-messages comprising a short message; according to the first message, allocating a storage space to the short message, the number of the storage units contained in the storage space being equal to the number of the sub-message contained in the short message, the storage units contained in the storage space having a location order; according to the first message and the sub-message identifier of at least one second message subsequently received, storing the first message and the at least one second message subsequently received into corresponding storage units in the storage space; and combining the sub-message stored in the storage units in the storage space.

Abstract: The method is performed as a client device and includes receiving a first message that includes a first data usage value. The first message is formatted according to a respective format. After receiving the first message, the method further includes acquiring a data usage template corresponding to the respective format. The method further includes receiving a second message that includes a second data usage value. The second message is formatted according to the respective format. The method further includes parsing the second message according to the data usage template so as to obtain a second data usage value.
