Skid-mounted separating metering device

A skid-mounted separating metering device relates to combined natural gas gathering and transmission equipment and aims to solve the problem that the traditional separating metering device influences the rolling development construction period of a petroleum field due to inconvenient movement, disassembly and the assembly. The device comprises a separator, a metering system, a pollution discharge system and a skid, wherein the separator and the metering system are connected through a pipeline and a valve; the pollution discharge system is connected with the separator through the pipeline and the valve; and the separator, the metering system and the pollution discharge system are installed on the skid. The skid-mounted separating metering device concentrates the separator, the metering system, the pollution discharge system, a valve member and an automatic control system thereof as well as an electrical system to the same skid to form integral equipment, is characterized by compact structure, regular shape, small occupied area, integral transportation, easy movement and the like, and is easy to realize standardization and serialization; in addition, the formed product of the skid-mounted separating metering device can satisfy the requirements for various working conditions during the gathering and transmission process and can realize the advance precasting so as to shorten the construction period, improve the working condition, quicken the productivity construction speed, and ensure reliable quality.
