Wherein the gas phase substance is introduced into the gas-liquid mixing pipe after being measured by the crude oil gas flow metering system through the pipeline. Wherein the liquid phase material flows into the crude oil water content monitoring system to measure the crude oil water content, then most of the liquid phase material flows into the liquid volume metering system to measure the oil well flow, and a small part of mixed liquid flows into the buffer pipeline system due to the fact that the pressure in the pipeline is higher, and finally flows into the liquid volume metering system.
