# Installation and Set-up

### **Pre-installation Checklist**

* **Check the manual version.** Make sure this manual matches both the hardware and firmware of your unit. See the [Manual and Product Version](https://docs.lorric.com/qr/fp-as310-english-v5/manual-version-2-0) page.
* **Choose a good location.** The flow must be stable and fully developed where the meter sits, so leave enough straight pipe both upstream and downstream of the meter. Install the meter in one of the following ways:
  * **Horizontal pipe:** mount the main unit on the *side* of the pipe (not on top or bottom).
  * **Vertical pipe:** the orientation of the main unit is not critical, but the fluid *must* flow upward (bottom to top).
* **Check the pipe and fluid compatibility.** Fluid chemistry and temperature vary widely between industries, and choosing the wrong materials can damage the meter. Before purchasing, confirm that the pipe and fittings suit your fluid in temperature resistance, chemical compatibility, and dimensions.
* **Avoid magnetic and electromagnetic interference.** This meter uses magnetic sensing. Do not use it with fluids containing magnetic particles, and keep the unit away from strong electromagnetic sources such as motors and solenoid valves.

## 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/fp-as310-english-v5/installation-and-setup.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.
