NetMeter-3P
Poly-phase Electrical energy meter/monitor with integrated web server and advanced datalogging.
Overview
The Hardware
The NetMeter-3P is a DIN rail mounted module that can measure over 50 electrical parameters from a 3-phase, split-phase, or up to 3-single phase loads.
It is wired-in, to measure voltage and current, using current transformers. The Z3 sensor continuously monitors and calculates power use and stores the data in an internal memory. Both real-time and historical data is available through the built-in network gateway. In addition to power information, the sensor also measures many other electrical parameters including:

The Gateway Capability
The built-in Gateway function bridges between the Sensor and the network. It serves up real-time and historical power consumption data from the sensor and transmits it throughout the network, and optionally over the internet, to any browser enabled device or HTTP client.
The Software
Since the NetMeter is accessible using a standard web browser, it requires NO software to be installed on your computer! Instead, the integrated Gateway has a built-in web server that utilizes Web 2.0 techniques enabling a highly interactive, real-time user experience. This eliminates the headaches of installing special software and drivers to be able to use the device.
The following capabilities are provided using the built-in web interface:

Open Platform
Z3 provides a documented Application Programming Interface (API) based on a cost-free license. It allows users and 3rd party developers to easily integrate the Z3 data into their custom application:
- Generate reports that consolidate enterprise-wide energy assets
- Combine energy data into integrated displays of information important to business operations (dashboards)
With the Z3 API, real-time and historical energy data is available using standard Web 2.0 programming techniques such as HTML, Javascript, and AJAX.
