Metering apparatus

The invention discloses a metering apparatus, which comprises a buffer tank, a filtering tank and a metering tank; the buffer tank is vertically arranged, and is used for buffering oil flow; the filtering tank is vertically arranged behind the buffer tank, and is used for filtering the oil flow, so that at least filtered oil flow is obtained; and the metering tank is horizontally arranged behind the filtering tank, and is used for metering the filtered oil flow. By connecting a gas pipe with the filtering tank, the metering apparatus solves the affection of gas on a metering result, increasing metering precision; and in addition, the metering apparatus is simple in structure, is reasonably designed, is easy to popularize and apply, and solves the problems of high single-well metering difficulty and high investment cost. 本发明公开了种计量装置，其中，包括：缓冲罐，竖直设置，用于对油流进行缓冲；过滤罐，竖直设置在所述缓冲罐之后，用于对所述油流进行过滤，以至少得到过滤后油流；计量罐，水平设置在所述过滤罐之后，用于对过滤后油流进行计量。本发明通过在过滤罐上连接气体管，解决了气体对计量结果的影响，提高了计量精度，另外，本发明的结构简单，设计合理，易于推广应用，解决了单井计量难度大，投资成本高的难题。
