探頭的安裝位置應安裝在管路側面，以避免管內氣體蓄積在上方產生空腔影響超音波訊號的收發，若因特殊狀況無法安裝在側邊，則必須確保管內隨時屬於滿管狀態空隙存在於探頭與管壁之間，由於超音波強度在空氣中會大幅衰減因此會嚴重影響訊號強度與品質，因此安裝時必須將耦合劑塗在探頭上與管壁之間，並排除任何氣泡，特別留意避免存在沙子顆粒等雜質，或過後的表面漆刮除。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.lorric.com/qr/fu-tx310-ultrasonic-flowmeter-manual-chinese-v2/2.-an-zhuang-fang-shi/2.2-chao-yin-bo-tan-tou/2.2.4-an-zhuang-fang-fa.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
