# 2.2.3 Installation location

The accuracy of an ultrasonic flowmeter is mostly determined by correct probe installation. If the installation method or location is incorrect, it may result in failure to achieve the desired results, or even an inability to send and receive ultrasonic signals. In general the conditions for the best installation location are as follows: 

● It is better to mount the ultrasonic probe on a longer tube or pipe; be sure to verify that the pipe is filled with liquid. 

● Installing the probe on the side of the pipe can reduce bubbles and interference caused by partially empty tube cavities. 

● Make sure the probe can withstand the temperature of the measuring point; the closer it is to room temperature, the better. 

● There are linings on the inner walls of some pipes. Though this product can be configured to be compatible with lined tubing, in practice this inner layer tends to block the transmission of ultrasound and thus the measurement results, so install as far as possible from this type of tubing.

**Correct probe installation will greatly enhance measurement accuracy.**

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.lorric.com/qr/fu-tx310-ultrasonic-flowmeter-manual-en-v3/2-installation-method/2.2-ultrasonic-probe/2.2.3-installation-location.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
