# How do I link a pulse counter device?

Configuring a pulse counter in cThings Cloud ensures accurate measurement and tracking of pulse-based readings, such as water or gas meters. Follow the steps below to set up your pulse counter correctly.

## Prerequisites

Before configuring the pulse counter, you must create the meter that will be linked to it. If you haven’t done this yet, follow our guide on [How to create a new device.](https://support.cthings.io/en/article/how-do-i-create-a-new-device-yzezuf/)

## Steps to link a pulse counter to a device

### 1. **Navigate to the Pulse Counter device page**
* Click **Devices** in the left-hand menu.
* Search for and select your Pulse Counter device.

### 2. **Access the configuration settings**
* On the pulse counter device page, click **"Device"** in the top-right corner.
* Select **"Edit Configuration"** from the dropdown menu.

### 3. **Enter the required details**
* **Pulse Ratio** – Input the pulse ratio value in the first field on the right-hand column (e.g. 10 pulses per 1 unit of measure).
* **Initial Read** – Enter the initial reading of the linked meter (e.g. 653240).
* **Meter Serial** – Provide the serial number of the meter you want to link this pulse counter to (this device should also exist in the cloud).
* **Unit of Measure** – Specify the unit of measurement (e.g. litres).

Once you've entered the necessary details, click "Update" to apply the configuration.
