椭圆齿轮流量计的测量部分主要由两个相互啮合的椭圆齿轮及其外壳（计量室）所构成，椭圆齿轮在被测介质的压差△p=pl-p2的作用下，产生作用力矩使其转动。
Measurement of elliptical gear flowmeter is mainly composed of two meshing elliptical gear and shell (measurement room) composed of oval gear in the measured medium pressure difference of p=pl-p2, which make the rotation torque. 在(a)所示位置时，由于P1>P2，在P1和P2的作用下所产生的合力矩使轮A产生顺时针方向转动，把轮A和壳体间的半月形容积内的介质排至出口，并带动轮B作逆时针方向转动，这时A为主动轮，B为从动轮，在 (b)上所示为中间位置，A和B均为主动轮；而在（c）上所示位置，P1和P2作用在A轮上的合力矩为零，作用在B轮上的合力矩使B轮作逆时针方向转动，并把已吸入半月形容积内的介质排至出口，这时B为主动轮，A为从动轮，与 (a)上所示情况刚好相反．如此往复循环，轮A和轮B互相交替地由一个带动另一个转动，将被测介质以半月形容积为单位一次一次地由进口排至出口． Obviously, on the map (a), (b), (c) shows, only said elliptic gear turned 1/4 weeks, and the discharge of the measured medium is a half moon volume. Therefore, the elliptical gear per week to the ratio of measured medium quality for half 4 times the product description the volume flow of Q through the oval gear meter meteor: Q=4n V 0 type: n - rotation frequency of elliptical gears (Rev / sec);
The 0 part of the volume V - half moon (beckham. ).
In this way, as described in the elliptical gear flowmeter half product 0 V under certain conditions, as long as the measured elliptical gear rotation speed n, can know the measured medium flow.
