HWg-PWR3 is a smart Ethernet gateway which captures data from up to 3 external meters on the M-Bus.
With external M-Bus (EN 13757) meters it can be used for remote monitoring a metering of water, electricity, gas or heat consumption.

Features:
- Connects 3 external meters equipped with the M-Bus (EN 13757-2) interface, can log 170.000 values (3 values every 15 minutes = 590 days).
- Converts the consumption (e.g. from [kWh] to a currency) without a need for computer or additional software.
- M2M communication protocols Modbus/TCP, SNMP and XML allow integration into more complex monitoring systems.
- Connected via LAN. Configuration via built-in web server.
- Sends an energy consumption report for user specified period as an e-mail attachment.
- Connected meter failure or out of specified range value sends an alert by e-mail, SMS or SNMP Trap.
- For Ring or SMS alarm use the HWg-Trigger software (external GSM modem required), or a HWg-SMS-GW3 gateway in the same LAN.
- With the HWg-PDMS software, logged data can be exported to MS Excel.
- Compatible with a range of third party SW (SCADA etc.). Examples for programmers on using the product are available in the HWg-SDK (Borland C++, MS Visual, VB, C#, PHP, JAVA and more).
- List of supported (tested) accessories/meters

Applications and usage:
- Remote monitoring of electricity meters in small server rooms and BTS
- Monitoring of energy consumption in rented premises
- Reading out energy consumption in remote or inaccessible areas
- Control over energy costs
- Checking for individual line overloads in three-phase wirings
- Checking for undervoltage in electric wirings
- Monitoring the flow of liquids
