# Probe installation

Installing a float level probe (Level Probe) is a simple operation, but it requires precision to ensure the alert triggers at the right time (high threshold or low threshold).

Here is how to proceed for an installation in an industrial or commercial environment:

## Detection threshold selection

Before fixing the probe, determine its function:

* **High Level Safety** (Overflow protection): The float is placed at the top of the tank to alert before the liquid overflows.
* **Low Level Safety** (Dry-run protection): The float is placed at the bottom to protect a pump or signal an empty tank.

## Mounting

The probe is supplied with a standard mounting bracket suitable for most uses. For more complex installations, an alternative installation method is also described below.

### Standard mounting: The fixing bracket

This is the preferred method for open tanks or accessible walls.

* **Implementation** : The supplied bracket is screwed onto the rim or upper wall of the tank. It allows the probe to be fixed at the desired height.
* **Advantage** : A clean, fixed installation that ensures the detection threshold will not change over time.

### Alternative mounting: The calm tube (or well casing)

If the configuration does not allow the bracket to be fixed (tank without a rim, irregular walls) or if the liquid is very agitated, a protective tube is used.

* **Implementation** : The probe is inserted into a vertical tube (perforated PVC type) fixed to the bottom or the walls. The tube guides the float and protects it from sudden liquid movements.
* **Advantage** : This method replaces the bracket by serving as a vertical guide. It is essential to avoid false alarms due to turbulence (pumping, filling).

## Transmitter housing installation

As with other LoRaWAN sensors:

* **Move the housing away** : Never place the radio transmitter inside a metal tank (Faraday cage effect). Fix it outside, ideally on a nearby wall or pole.
* **Height** : Keep it in a high position to ensure optimal signal propagation to your gateway (Gateway).

Once the installation is complete, **operate** manually the **float** **from bottom to top** to **check** that the radio message is properly received by your monitoring system or your BMS.
{% endhint %}

## 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://enless.gitbook.io/centre-aide/guides-installation/documentation-en/products/editor-21/use/probe-installation.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.
