&#x20;<mark style="color:red;">\*</mark> <mark style="color:red;"></mark><mark style="color:red;">**IP66 Rating**</mark>\
IP66 stands for Ingress Protection 66. The IP rating is a standard that classifies the degree of protection provided by an electrical enclosure against the intrusion of foreign objects. The format is IPXX, where XX represents two digits: the first digit indicates the level of protection against contact and solid foreign objects (dust protection), and the second digit indicates the level of protection against water ingress. A higher number indicates a higher level of protection. For IP66: the first 6 means complete protection against dust ingress; the second 6 means protection against powerful water jets without harmful effect.

<mark style="color:red;">\*\*</mark> <mark style="color:red;"></mark><mark style="color:red;">**Accuracy Notice**</mark>\
Accuracy is calibrated under controlled conditions using clean water at ambient temperature with CNS UPVC pipes. Actual performance may vary due to fluid properties, pipe conditions, installation, and environmental factors.

<mark style="color:red;">\*\*\*</mark> The device is calibrated with normal temperature water. Fluids with different viscosities may have different results, and may also change the minimum and maximum flow velocity.

<mark style="color:red;">\*\*\*\*</mark> The flow velocity range may be slightly different due to factors such as piping diameter and fluid coefficient.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/fp-as510-paddle-wheel-flowmeter-manual-en-v2/exterior-spec-model.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.
