Wi-LEM
Wi-LEM: PLUG & SAVE!
The Wireless Local Energy Meter (Wi-LEM) is a complete sub-metering network that is fast and easy to install. The Wi-LEM family consists of:
- Energy Meter Nodes (EMN) - an assembly of 1 to 3 current transducers with its signal processing module. They can be deployed to measure energy consumption at any point in the power cabinet and transmit the data.
- Wi-Pulse - a dual inputs pulse counter used to transmit values from electric, gas and water meters.
- Wi-Zone - a temperature and humidity transducer battery powered.
- Mesh Nodes - a repeater linking various Nodes. They enable wireless communications throughout a large installation.
- Mesh Gate - a gateway managing the mesh network. It provides data through serial interface to a PC.
Wi-LEM Key Benefits
Compared to traditional wired energy sub-meters network, Wi-LEM brings key benefits at two levels:
- Inside the cabinet installation
- Network installation & commissioning
Inside the cabinet installation:
| Less components to install | Saves time & space |
| Split core current transducers | Saves time: no need to disconnect main cable |
| Wiring simplified | Saves time & reduces risk of errors |
| Compact size | Saves time & space: no need for an auxiliary cabinet |
Network installation & commissioning:
| EMN Scaling factor auto-configuration | Saves time & reduces risk of errors |
| Eliminate wires cost & cabling risk | Saves time & reduces cost linked to wired communication busses |
| RF network visualization (RSSI) | Saves time & remote assistance during the installation |
| Automatic identification of new EMN | Scalability & time saving for future site extension |
