Carlo Gavazzi energy meters

Energy Management

Carlo Gavazzi is a market leader in Energy Monitoring technology with one of the broadest range of products in the industry. With over 25 years of experience, Carlo Gavazzi knows what it takes to manufacture meters that are designed to withstand the rigours of your toughest applications. With local sales and support centers located in 22 countries and independent distribution in over 100 countries, Carlo Gavazzi product and technical support is available around the world.

Why Monitor Energy

Energy management is not only the metering and billing for energy consumption, it is also tied in with the general principle of energy efficiency. According to the International Energy Agency (IEA), 'Energy efficiency is a vital component to meet the challenges faced by the energy sector, which range from ever increasing global energy demand, to concerns about energy safety, climate change, local air pollution, and the affordability of the energy supply'. Therefore, the monitoring of energy consumption is an important first step, for the achievement of energy efficiency goals. Energy efficiency is the key for cost effective energy transitions and the single energy resource that all countries own in abundance. Strong energy efficiency policies are vital to achieving the key energy-policy goals.

Connecting to the Edge and Beyond

Carlo Gavazzi's UWP is a powerful Edge controller that allows up to 100 meters to be monitored and it provides a user configurable web interface that can be accessed via your standard web browser. This allows you to monitor energy consumption, view trend graphs of logged electrical data (current, voltage, power, etc). In addition the UWP also provides a vast array of connection options to fog/cloud systems including :

In addition to these features, the UWP also includes a Modbus driver creation tool that allows you to communicate with virtually any device that uses Modbus - even if it is not a Carlo Gavazzi meter. This allows you to leverage your existing metering devices and still experience the power of the UWP controller.

Wireless Solutions : Point-to-point(s) using long range LoRa

In many applications it is not feasible to use a wired communication due to expense or the nature of the terrain. Carlo Gavazzi offers a powerful solution for long range, secure, licence free wireless communication based on LoRa. To accomplish this, you just need to plug a wireless module (UWPM) into the side of the UWP controller. This lets you access up to 50 remote meters at a distance of up to 10 Km in open air. There are no annual fees nor SIM cards required.

Up to 3 UWPM modules can be connected to a UWP controller giving a total of up to 150 meters that can be monitored wirelessly. If you have a combination of both wired and and wireless device, this is no problem as you can also access meters via RS485 and Ethernet as well.

Typical applications include:

Wireless Solutions : LoRa-Wan

Carlo Gavazzi has developed the UWPA wireless interface module that allows a Carlo Gavazzi meter to be connected to public and private LoRa networks. Simply connect the UWPA to our meter via RS485 and the energy data from the meter will be available through your LoRa-Wan network. This is ideal for Smart Cities or areas that are served by an existing LoRa-Wan network and they may already be using LoRa to read exisiting devices such as water meters.

Applications

Sub Metering
Sub Metering

Sub-metering, is an important application for either direct billing or cost allocation. This metering consists not only of electrical consumption, but also other metered utilities such as gas and water.

When used for billing in commercial applications, a submetering system determines energy use by individual user. This is common in apartment buildings where the owner can have one utility meter and then allocates the cost based on usage among tenants who each have an individual submeter installed. This also has uses for shopping centres, transportation terminals, marinas, campsites or other venues that have individual tenants leasing spaces or kiosks.

Data Centers and Telecommunication Stations
Packaging

Data centers are directly or in-directly the back bones of any company - any downtime is costly and affect your ability to conduct business. In addition, these data centers are also large consumers of electrical energy.

Due to their critical nature (99.9% uptime) it is important to monitor not only the energy usage but also the power profile and power quality in order to anticipate problems before they result in shut-downs. According to the Ponemon Institute, the average cost per minute of unplanned data center downtime is $5,900 USD. Critical components include chillers, fans and servers.

EV Charging Stations
Food znd beverage

EV charging stations is an extension of the sub metering application. Each charging station has an energy meter that is approved for revenue metering. The user of the charging station is billed for their actual electrical usage.

Panel Builders, Switch Gear and MCCs
Pumps

Energy Meters are commonly used in Control Panels and Motor Control Centers. They provide a visual indication of the current draw, voltage and power factor of the various motors.

In addition, they also monitor the motor power which is a linear representation of the actual load on a motor. When tied to a digital output or when read via a communication bus, they are able to provide alarms indicating plugged filters, belt slippage and excess load in general.

Production Machinery
Lighting

For all production machinery that manufacture or package product, Energy Consumption is part of the equation in the final cost of the product. A Carlo Gavazzi meter or transducer can be used in the machine to measure and provide the energy usage information to the controller.

Also, monitoring the power profile is an excellent method of obtaining a performance and efficiency profile of the machinery. This information, when examined over a period of time can identify equipment problems, material shortages or poor shift/operator performance.
