X理想的安装方式是竖直安装，流体应自下而上（如图2）流经传感器，这样安装的主要优势是避免产生气泡。因为空气的介电常数大约是1，和油的介电常数比较接近，如果油内夹杂气泡或者油在流动过程中产生气泡，都将影响测量。’
It is ideal for X to be installed vertically. As the fluid flows through the transducer from the bottom up (as shown in Fig. 2), vertical installation has the major advantage of avoiding bubble generation. Since the dielectric constant of air is 1, relatively close to that of oil, if there are bubbles in the oil or if bubbles are produced during the oil flow process, the measurement will be affected.

如果X用于测量较大的管道，也可以把它安装在一个旁路上，但是必须注意，旁路中的流体要具有典型代表性，确保水与油混合充分。
If X is used for measuring a large pipe, it can also be installed on a bypass, but attention should be paid to making sure that fluid in the bypass is representative and that water and oil are well mixed.

X对测量介质的流速范围是有要求的，流速太低会造成水油分离，使读数没有代表性；流速过高可能会使气体突然喷发，造成读数过低。因此，将仪表安装在流体最有代表性的位置是至关重要的。
X also has requirements for flow velocity range of the measured medium, as water and oil will be separated and the readings will be unrepresentative if the velocity is too low while too high velocity will lead to abrupt gas eruption and hence very low readings. Therefore, to install the meter on a representative position where the fluid is most representative is crucial.
