本文介绍了一种利用流体脉动原理测量不经气、液分离的油井气、液产量的多相流量计。文中对该多相流量计的数学模型进行了推导，得出了一种实用的多相流量计的数学模型。
This paper introduces a multiphase flowmeter that uses the principle of fluid pulsation to measure gas and liquid production without gas and liquid separation. In this paper, the mathematical model of multiphase flowmeter is deduced, and a mathematical model of practical multiphase flowmeter is obtained.
