M-BUS is a standard in energy metering. As opposed to pulse counters, it works with absolute values (acquired data can be used as an argument against the utility bill), and at the same time allows working with additional quantities, such as voltage, current, flow, drift, etc.
In a typical scenario, HWG-PWR remotely monitors an electrical network, and the user can simultaneously monitor several parameters:
- Total electricity consumption
- Instantaneous electricity consumption
- Instantaneous voltages at individual lines
- Instantaneous current flowing through each line
- Power factor (cos ϕ) of individual lines
