# 2.3.2 Analog output
This product also has a built-in 4-20-milliampere analog power output signal which provides analog output of the measured values. It is used as follows: **(**The 4-20mA output resolution is specified as 12-bit, ensuring precise analog signal representation**)**
● Outputs include flow rate, flow velocity, upstream temperature, downstream temperature, liquid sound velocity, and upstream/downstream temperature differential.
● Upper and lower limits can be customized to provide the required range of output.
● The 4-20mA is 3-wire wiring. As long as power supplied by device DC, the external power supply is no need for 4-20mA terminal. As below image, please refer to do wiring.

## 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/2.3-temperature-sensor-analog-output/2.3.2-analog-output.md?ask=&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.
