Even though they can sometimes collect data from same delivery points, sensors and meters are not interchangeable on the platform, and both have specific properties. 

Definition of Meters and Sensors on the N'gage platform:

• Meter: 

A meter is an object linked to your site that records indices or consumption measurements of a specific fluid. It is necessarily attached to a site and allows for the association of billing data via the delivery point and manual readings with its code.

• Sensor: 

A sensor is an object on your site that records and automatically sends indices or measurements of a fluid or an influencing factor (e.g., occupancy, temperature, DJU) through a third-party network (LoRa, 4G, Sigfox, WiFi). It is also necessarily attached to a site and allows for the association of telemetered data via its identifier.

Where to Find Your Meters and Sensors on the Platform

You can view your meters and sensors associated with a site through the synoptic page in the My Sites tab. The synoptic page gathers the site's metering plan.

• Meters are represented by a circular symbol placed on a fluid (e.g., natural gas).

• Sensors are represented by a rectangular symbol with a number indicating the count of sensors attached to a particular meter.

Different Types of Meters and Sensors

Types of Meters

1. Supply Meter: Corresponds to a general delivery point on-site. You can associate it with billing data and reading data (via the code) and attach telemetering sensors to it.

2. Stock Meter: Used exclusively for storable energies, it keeps track of your reserves. On the platform, you can record deliveries for this type of meter.

3. Sub-Meter: Represents a sub-metering point measuring usage or transformation consumption on the site. You can associate it with reading data (via the PDL number) and attach telemetering sensors to it.

Types of Sensors

1. Consumption Sensor: Collects a stream of consumption data and integrates it onto the platform. It is generally linked to a meter. Example: An Enedis sensor transmitting the load curve associated with a meter.

2. Measurement Sensor: Collects a stream of measurement data (e.g., temperature or humidity) and integrates it onto the platform. It is generally not linked to a meter but to a measurement point. Example: An Adeunis Confort sensor measuring the temperature and humidity of a room.
