Energy Meters

In New Zealand, it's important to recognize that electricity isn't free unless generated from alternative sources like solar power. Even then, accurately measuring the amount of electricity produced is essential.

For businesses facing high energy costs, selecting the right energy meter is vital. Energy meters, also referred to as electrical meters or power usage meter , are key devices for measuring and recording electricity consumption over time in units. These meters deliver precise and reliable readings, ensuring high-quality data to help manage energy usage effectively and reduce costs.

It’s possible to buy a variety of energy meters that record information, such as power, frequency, voltage, current and wattage. Moreover, energy consumption is an important factor for both environmental and cost-reduction purposes. By integrating an energy meter into your power management system, you gain valuable insights into energy efficiency, enabling you to reduce expenses and minimise your environmental footprint.

Types of Energy Meters

Choosing the most appropriate energy meter for your business is a critical decision based on your business's nature as well as the main hours of operation. Following are the types available in our catalogue for you to choose from:

Frequency Meter

A frequency meter is a specialised type of energy meter that measures the frequency of an electrical signal. This is important in applications where the frequency of the power supply needs to be precisely monitored, such as in industrial settings or power generation facilities. Frequency meters can also be used to detect anomalies in the power supply, such as fluctuations or deviations from the standard frequency.

Digital Power Meter

Digital power meters offer high accuracy, a wide range of features, and a clear digital display for easy reading. Digital power meters can measure various electrical parameters, including voltage, current, power, energy consumption, and power factor. They are suitable for a wide range of applications, from residential and commercial buildings to industrial facilities and renewable energy systems.

Analogue Power Meters

Analogue power meters feature a rotating disc or pointer to indicate energy consumption. Then, utility companies determine your energy usage and the amount they should charge you by comparing two readings—your current and previous readings. While they are less accurate and feature-rich than digital meters, they are still used in some applications due to their simplicity and low cost. Analogue power meters are typically found in older homes and buildings, but are being gradually replaced by digital meters.

Key Features of Power Usage Meters

Power usage meters from RS NZ come with a variety of features that enhance their functionality and usability and cater to different needs and applications

• Display Types: Power usage meters typically feature either LCD displays or analogue dials to show energy consumption data. LCD displays offer clear and precise digital readings, while analogue dials provide a more traditional visual representation. Some meters may also include backlighting or adjustable contrast for improved visibility.
• Mounting Options: Power usage meters are designed for various mounting options, including panel mounting, DIN rail mounting, and direct plug-in. Panel-mounted meters are typically installed in electrical panels or enclosures, while DIN rail-mounted meters are suitable for equipment racks. Direct plug-in meters can be conveniently plugged into a wall outlet for easy installation and portability.
• Measurement Parameters: Power usage meters can measure a range of electrical parameters, including voltage, current, power, energy consumption, frequency, and power factor. The specific parameters measured depend on the type and functionality of the meter. Some advanced meters may also offer features such as harmonic analysis, data logging, and remote communication capabilities.

Applications of Energy Meters

Calculating home energy consumption used to be complicated, involving expensive appliances, unit conversions, meter readings, and estimated bills. But now, with an energy monitor, you can see your energy usage in real-time and know exactly how much it costs to run devices like your washer or dryer.

Energy meters are versatile tools used in a wide range of settings, and here are some key applications:

• Industrial Settings: In industrial environments, energy meters track and optimise energy usage for various processes and equipment. This helps identify areas where energy consumption can be reduced, leading to cost savings and improved efficiency. Power consumption meters and electric usage meters are commonly used in factories, manufacturing plants, and other industrial facilities to monitor energy usage for individual machines, production lines, or entire departments.
• Commercial Buildings: Energy meters are used to monitor and manage energy consumption for lighting, heating, cooling, and other electrical systems in commercial buildings. Electricity meters and power meters are commonly installed in offices, retail stores, and other commercial spaces to track energy usage and identify areas for improvement.
• Residential Homes: Energy meters are readily available for homeowners to monitor their energy usage and identify appliances or habits that contribute to high energy consumption. This awareness can lead to more conscious energy usage and potential cost savings.
• Power Plants and Utilities: Energy meters are critical components in power plants and utility grids, where they are used to measure and monitor the generation and distribution of electricity. This data is essential for ensuring grid stability, optimising power generation, and accurately billing customers for their energy usage. Electric power meters and power usage meters are used extensively in power plants and substations to monitor the flow of electricity and ensure efficient energy distribution.
