高压共轨试验台配件功能参数：

高压共轨试验台配件包含油路 电路驱动等各位置部件，其中，流量传感器为关键配件之一：

该部件的作用是采集泵及喷油器流量的传感器，是椭圆齿轮流量计（又称排量流量计，齿轮流量计），属于容积式流量计一种，在流量仪表中是精度较高的一类。

容积式流量计，又称定排量流量计，简称PD流量计（positive displacement meter），在流量仪表中是精度较高的一类。它利用机械测量元件把流体连续不断地分割成单个已知的体积部分，根据测量室逐次重复地充满和排放该体积部分流体的次数来测量流体体积总量。

Functional parameters of accessories of high voltage common rail test bench:

High voltage common rail test bench accessories include oil circuit drive and other position components, among which flow sensor is one of the key accessories:

The function of this component is to collect the flow sensor of the pump and fuel injector. It is an elliptical gear flowmeter (also known as displacement flowmeter, gear flowmeter), which belongs to a kind of volumetric flowmeter and has a high accuracy in flow instruments.

Positive displacement flowmeter, also known as constant displacement flowmeter, or PD flowmeter for short, is a class of flow instruments with high accuracy. It uses mechanical measuring elements to continuously divide the fluid into a single known volume part, and measures the total volume of the fluid according to the number of times that the measuring chamber repeatedly fills and discharges the fluid in this volume part.
