# \[留檔]瞬時流量及誤差
### 瞬時流量及誤差
本流量計的最大可能誤差為 0.5 % F.S. + 2.5 % O.R.，換算為在不同流速下最大可能誤差與顯示數據的關係如下圖：

### 流速
本畫面顯示的流速數據基於流量計內設定的管路幾何及流體聲速數據。
### 累積流量
累積流量畫面在被人為歸零前會持續計數。
累積流量的上限是 999,999,999 Litre 。

## 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-es-ultrasonic-flowmeter-manual-chinese-v1/liu-dang-shun-shi-liu-liang-ji-wu-cha.md?ask=&goal=
```
`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.
