The HWg-PWR12 is a smart Ethernet gateway which can be used capture data from up to 3 external meters using MODBUS (M-BUS). Using external M-Bus (EN 13757) meters the device can be used to remotely monitor the metering of water, electricity, gas or heat consumption. The M-BUS data can be made available over the web (using graphics), SNMP, email and log files. The PWR12 alarms for out-of-range/abnormal values via email or SMS which can be sent via the HWg-SMS-GW3 gateway when installed on the same local area network.
The PWR12 has a built-in web server for ease of configuration and can be remotely monitored over the internet using the SensDesk Cloud portal or SensDesk Mobile App (iOS or Android).
HWG-PWR devices are designed to monitor external M-BUS meters over a network using Machine-2-Machine (M2M) protocols including MODBUS/TCP, SNMP, XML and others. The devices can support over 50 SNMP and SCADA applications and can be used as a standalone solution or built-into in a wide range of monitoring and control systems.
Connect PWR12 to external meters using the MODBUS (EN 13757-2) interface and log up to 170,000 values (3 values every 15 minutes = 590 days)
Machine-20-Machine (M2M) communication protocols include MODBUS/TCP, SNMP and XML
Connected via local area network and configured via a built-in web server.
Connected meter failure or out of specified range value sends an alert via email, SMS or SNMP
Use the HWg-SMS-GW3 gateway for a Ring or SMS alert on the same LAN.
Data logging can be exported using the HWg-PDMS software into Microsoft Excel.
Compatible with a range of third-party software platforms including SCADA applications. Examples available in the Borland C++, MS Visual, VB, C#, PHP, JAVA and more.
Energy Monitoring Gateway
Sends an alarm message (email, SMS or SNMP) in the event of failure or value out of a specified range
Converts energy consumption from kWh to monetary values without a computer or additional software
Periodically sends energy consumption reports for a given period as an email attachment
8xDigital Inputs (DI) for detecting single-phase 110/230Vac power outages
Logs selected values and displays graphs over a web interface
Actively uploads data to a portal using the HWg-Push protocol
Remote monitoring of electricity meters in server rooms and telecoms sites
Energy consumption monitoring in rented premises
Reading energy consumption data in remote or inaccessible areas
Control over energy costs
Checking individual supply line for overload in three-phase installations
Checking for under voltage in electrical installations
The HWg-PWR12 device monitors energy consumption using standard external energy meters. The devices can monitor a range of electricity, water and gas meters from different manufacturers.
The advantages of using third-party MODBUS meters:
Wide range of meters using the EN13757 (M-Bus) interface available. It is easy to use special-purpose meters (non-standard form factor or measurement range e.g. indirect electricity meters rated up to 1000A).
M-Bus meters frequently provide extended information e.g. total consumption and immediate values, voltage at different phases and power factor.
Values from certified meters can be used for billing purposes.
