西门子 Sitrans FC430
a pioneering coriolis flow meter
一种创新的科里奥利流量计
With the Coriolis effect, a physicalforces explained .
科里奥利效应可以用一种物理作用力来解释。
It acts on a medium that is accelerated in arotating system,
这种力作用于在旋转系统中做加速度运动的介质上，
like a ball on a rotating disc.
就像旋转圆盘上的球一样。
Its movement is straight.
它的运动轨迹是一条直线。
However，if the observerturns with the disc ，
然而，如果观察者随圆盘一起旋转，
the ball is apparently deflected .
那么球的运动轨迹就会明显偏离直线。
The same effect occurs with a water hose
同样的效应会出现在一个水管围绕它
that rotates around its own axis ，like a skippingrope.
自己的轴心进行旋转时，像跳绳一样.
As soon as water flows through, the hosealso twists .
一旦水在水管中流动，水管就会产生扭曲。
The effect also appears with an oscillatingmovement .
这种效应也会出现在振荡运动中。
The twisting is stronger or weakerdepending on
扭曲的强弱程度取决于
the amount of water flowing through thehose.
流过水管的水量。
This effect allows the mass of liquids orgases to be determined .
通过这种效应可以确定液体或气体的质量。

according to the same principle .
根据同样的原理进行工作。
Two symmetric metal tubes are set vibrating.
两根对称排列的金属管中央部分的
This is ensured by a driver coil in thecentral section .
驱动线圈使得金属管处于振动状态
The tubes oscillate with a resonance fre to a tuning fork.
金属管像音叉一样，以共振频率振动。
The oscillation is measured precisely bytwo pickups
这种振动是由安装在金属管入口和出口的
at the inlet and outlet sections ,
两个传感器来准确测量的。
If liquids or gases now flow through the tubes,
如果液体或气体流过金属管，
a phase shift occurs as with a water hose.
金属管就会像水管一样出现相位移动。
The pickups measure the spatial andtemporal displacement .
传感器测量金属管在空间和时间上的位移。
This determines the amount of liquid or gasflown through the tubes.
这就能确定流过金属管的液体或气体的量。
The greater the amount ,the stronger
如果液体或气体流过金属管的量越大，
the tubes oscillate outwards.
金属管向外振动的幅度就越大。
Siemens presents yet another Coriolisdevice for measuring mass flow.
西门子呈现的不仅仅是一台测量质量流量的科里奥利设备。
Thanks to the precision of every detail andits compact form，
凭借其每个部件的精密度和它紧凑的结构，
the Sitrans FC430 represents a smallrevolution.
Sitrans FC430代表了一个小型的技术革命。
A multi-parameter flow meter with maximumreliability，
一个拥有极高可靠性的多种参数的流量计，
in addition to the mass, it determines the densityof the medium.
除了测量质量流量以外，还测量介质的密度。
Denser media have lower fre，
介质的密度越大，其中的振动频率就越低，
put otherwise ，water oscillatesat a lower frequency than air
例如，物体在水中的振动频率比在空气中的振动频率低。
From the measurements multiple parameters,such as volume
从测量结果中可以推导出液体中的多种参数，
or concentration of substances in a liquid canbe derived .
例如介质体积或浓度。
Data and results are stored internally andon the innovative sensor flash.
数据和结果存储在系统内存和极具创新的闪存中。
They are available at all times as backups,
它们可以随时作为备份使用，
just like the audit trail function and allcertificates .
正如审计跟踪功能和所有证书。
