腰轮流量计是一种转子型的容积式流量计,也称为罗茨流量计。它的存在已经有100多年的历史了。其结构特征为:在流量计的壳体内有一个计量室.计量室内有一对可以相切旋转的腰轮(由此得名腰轮流量计)。
Roots flowmeter is a rotor type volumetric flowmeter, also known as Roots flowmeter. Its existence has been 100 years of history. Its structure is characterized by: a metering chamber in the housing of the flowmeter, and a pair of torsion wheels (hence the name of lumbar flowmeter) which can rotate tangentially in the metering chamber.
