Monitoring concentrator of energy consumption data from networks of distributed smart meters and web server Data Manager
The Esaware EW900 Data Manager is a data collector able to manage a network of Esaware Meters of the EW800 family in order to monitor is a distributed way the plant energy consumption. Up to 250 DEM can be managed for an accurate measurement of electrical parameters and line quality.
In addition EW900 can collect data from many different types of smart sensors like gas, water, air, steam meters, all connected on the available hardware interface and dedicated protocols.
The internal database can then be accessed by remote users via http/https to the embedded web server, either using a wired or wireless connection. A full control and management of machinery energy consumption and several line quality parameters help the energy manager to take the right decisions for the energy efficiency provisions and for the predictive maintenance.
Features:
- Electric energy , gas, water air, steam consumption data collection
- Active, reactive, apparent power and energy measurements.
- Configurable data management (instant values, trend, max, min etc.)
- Configurable data graphic visualization
- Wired or wireless (Wi-Fi, 3G) connection option available
- Optional hardware interfaces and communication protocols: RS485 ModBus, Radio Sub 1Ghz (868MHz)
- Up to 250 ESA DEM can be configured for rthe monitoring of energy an line parameters, including harmonics (1st…51th), THD
- Self configurability of the DEM network
- Remote access to internal database via http/https or data export via ftp
