The HWg-PWR captures data from 12 external meters on the M-Bus and connects the data to IP. M-Bus data are available over Web (graphs), SNMP, Emails or Log files. With external M-Bus (EN 13757) meters it can be used for remote monitoring/metering of Electricity power, Heat, Water or Gas consumption. There are standard 3rd party M-Bus compatible meters on the market. HWg-PWR is reads data form external 12 M-Bus meters (EN 13757) and analyzes them. Up to 100 metered values can be shown on the WEB by graphs or monitored over SNMP.

The HWg-PWR M-Bus IP meter supports alarming through E-mail or SNMP traps whenever a defined value exceeds limit (current overload).

The M-Bus metering standard (EN 13757) is supported. There are certified meters with M-Bus interface from 3rd party vendors on the market (Electricity, Heat (calorimeters), Gas & Water meters). >> Supported M-Bus meters

With HWg-PWR you can simply monitor energy costs (Datacenters, Remote sites, Office buildings, Family houses)

Certified Electricity power meters with M-Bus interface are used for energy metering. You can use this data for billing your customers. No current or 1 phase limits. Simply install one 63 Amperes power meter per cabinet and monitor it remotely over SNMP.

Usage examples

• Remote monitoring of power meters in small server rooms and BTS
• Monitoring of energy consumption in rented premises
• Acquiring energy consumption readings 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

For the first steps, we recommend to use the HWg-PWR 1f 230V mobile box.
