HWg-PWR 3/12/25: medidor inteligente M-Bus de consumo de energía

HWg-PWR es convertidor de M-Bus a Ethernet (SNMP) para la medición del consumo de energía y corriente. Se pueden conectar 3, 12 o 25 medidores externos M-Bus (agua, gas, electricidad, calefacción).

Note: Shorted version - full details in english version.

HWg-PWR 3/12/25 HWg-PWR captura los datos de 3,12 o 25 medidores externos M-Bus. La unidad monitoriza el consumo energético y alerta a través de Email y SMS en el caso de valores fuera del rango.

Todos los valores de los medidores externos están disponibles para ser procesados a través de SNMP, Modbus/TCP o Web.

HWg-PWR 3/12/25 se puede usar independientemente, sin la necesidad de un PC local. La interfaz Web muestra los gráficos de consumo, que son enviados vía email una vez por día, semana o mes.

Con el HWg-PWR 3/12/25 puede crear fácil y rápidamente un sistema remoto de control del consumo energético. Aplicaciones típicas son los centros de datos, centros comerciales, áreas industriales y edificios de oficinas.
Los sensores Individuales con salida M-Bus (medidor de electricidad, agua, gas, calefacción y otros) son productos de terceros. La Interfaz de M-Bus soporta más de 30 fabricantes líderes. Puede usar los medidores externos para cualquier rango de corriente, Cos ϕ etc..

Advantages of using third-party M-Bus meters

  • Vast range of meters with the EN 13757 (M-Bus) interface to choose from.
    It is easy to use special-purpose meters (non-standard form factor or measured range, e.g. indirect electricity meters rated up to 1000 A).
  • M-Bus meters frequently provide extended information (total consumption and immediate values, voltage at different phases, power factor, etc...).
  • Values from certified meters can be used for billing purposes.

M-Bus or S0 pulse counter

S0 is a legacy system of counting pulses that correspond to a certain amount of energy.
The M-Bus interface is the current standard for energy metering. Unlike pulse counting (S0), it works with absolute values (that can be used for customer billing). In addition, M-Bus provides more values, such as the immediate current and voltage, cos φ, and so on.

An S0 to M-Bus converter can be used to connect S0 devices:

Caution: We recommend to always check and test what values does the manufacturer guarantee at the M-Bus interface.

Applications

  • 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

Collecting data from 1 to 25 M-Bus electricity meters

  • Various energy meters (equipped with the M-Bus interface) are connected to the HWg-PWR unit.
  • All values are available to external software over LAN and SNMP.
  • Energy consumption details can be viewed using the Web interface or an iPhone or Android app.

Server room: Energy consumption monitoring + phase outage detection

  • Up to 25 electricity meters measure the single-phase or three-phase consumption of the cabinets.
  • Up to 8 inputs can detect phase outages.
  • When a phase fails, a warning can be e-mailed.
  • Upon an alarm (phase failure or current out of range), a text message alert can be sent to a mobile phone via an external SMS Gateway.
  • Energy consumption data can be connected to any SCADA system (Modbus/TCP) or accessed over SNMP.

Measuring energy consumption with S0 pulses and M-Bus meters

  • Modern electricity meters with the M-Bus interface can be connected to HWg-PWR directly.
  • Older electricity meters with a S0 pulse output can be connected using a “S0-M-Bus” converter.
  • Current consumption charts are available through the HWg-PWR web interface.
  • Every day, week or month, HWg-PWR e-mails a report. The e-mail contains a billing statement including KWh and a conversion to currency.
  • When the current consumption exceeds or drops below a set threshold, the unit sends an e-mail alert.

Remote energy metering with a central WEB portal

  • Various energy meters are connected to a single HWg-PWR unit.
  • Each unit has a WEB interface for configuration, viewing logs, etc.
  • All consumption data are uploaded to a central portal using the HWg-Push protocol.
  • The central portal (e.g. SensDesk) generates detailed analyses and statistics concerning energy consumption.

  • What values can HWg-PWR display?
    HWg-PWR can display any values and quantities that are accessible over M-BUS from the respective meter.
  • Is it necessary to use meters supplied by HW group?
    No. Any device from any (third-party) manufacturer can be connected to HWg-PWR, as long as it has the M-Bus interface.
    To help you choose, we have compiled a list of tested meters. See the link in the Download box.
  • How many devices / values can be connected at once?
    The M-Bus supports up to 250 connected units. HWg-PWR supports a maximum of 3 / 12 / 25 devices.
  • How many different variables can be monitored?
    HWg-PWR 3 / 12 / 25 supports a maximum of 100 variables. The particular combination is not relevant, e.g. 25x4 (25 meters x 4 variables each) or 10x10 variables are possible.
    Each variable can be logged and monitored by e-mail.
  • Is it possible to use electricity, water and gas meters from different manufacturers on a single bus?
    Yes, as long as the devices use the same communication speed (typically 2400 b/s)
  • How far away can be the M-Bus meters from the HWg-PWR unit?
    At 300 Bd, the cable segment length must not exceed 1000 m (max 350 m at 9600 Bd).
  • Is it possible to connect Wireless M-Bus meters to HWg-PWR?
    Not directly. The HWg-PWR smart gateway supports wired M-Bus only. However, we have successfully tested a wireless-to-wired M-Bus converter.
     
  • Where can I find the prices of your devices?
    Ask our distributors, or request a quote directly from us using the form at this page.
  • What is the warranty?
    The standard warranty is 2 years, can be extended upon request.
