Multi Function Panel Meters

Multi-function panel meters, also known as multi-function energy meters, process meters, and multipurpose meters, are versatile instruments used to measure and display various electrical parameters, such as voltage, current, power, and frequency. These digital panel meters provide a centralised and convenient way to monitor critical electrical parameters and ensure the smooth operation of electrical systems.

What Are Multi-Function Panel Meters

Multi-function panel meters are digital touch-display devices that use a free drag-and-drop style software package for rapid development and measurement of industrial display and panel applications. Users can build multi-screen interfaces without manual code input, perfect for a wide range of industrial processes. They are a modern replacement for traditional single-function analogue meters, offering greater flexibility and data visibility.

How Multi-Function Digital Meters Work

DC digital multi-function meters and other multi-function digital meters operate by utilising various sensing and measurement technologies to capture electrical parameters. They typically utilise specialised sensors or circuits to measure voltage, current, power, frequency, and other relevant quantities.

The measured values are then converted into digital signals using analogue-to-digital converters (ADCs). These digital signals are processed by a microprocessor within the meter, which performs calculations, applies scaling factors, and displays the results on a digital display. Some advanced multifunctional meters may also include communication interfaces, such as RS-485 or Ethernet, to transmit data to external systems for monitoring and control. This allows for remote monitoring and integration with building management systems.

What Are Multi-Function Panel Meters Used For?

Multi-function panel meters are a versatile and cost-effective alternative to traditional panel meters. They allow you to program and display digital meter measurement styles and input signals previously provided by a traditional panel meter.

They're suitable for a range of low, medium, and high-voltage control panels, gensets, building management, energy and power management systems as they are extremely effective at measuring AC or DC current or voltage within an electrical system. Their programmability allows them to adapt to changing needs and provide a comprehensive overview of electrical system performance.

How Do You Use Multi-Function Meters?

Multifunctional panel meters often work in conjunction with current transformers (CTs) for easy installation, especially when measuring high currents. You can select the type of meter style you want, including bar graph, analogue-style, and digital options.

The display can be personalised by selecting preferences including text, colour, and voltage input scaling. Once any programming is finished, you can save all selections to the meter and your computer, detach the unit, and mount it into a panel. This makes installation and configuration relatively straightforward, even for complex systems.

Key Features to Consider in Multi-Function Meters

Here are some key features to consider when selecting a multi-function panel meter:

• Measurement Parameters: Look for multi functional meters that measure the parameters important to your application, such as voltage, current, power, energy, frequency, and power factor. More advanced models may also measure Total Harmonic Distortion (THD).
• Accuracy: Accuracy is usually specified as a class (e.g., Class 0.2, Class 0.5) according to standards like IEC 60364. Higher accuracy multifunction meters are crucial for critical applications where precise readings are essential.
• Display Type: Consider the display type and readability of your multi function digital panel meter. Options include LED or LCD (with or without backlight). Multi-screen interfaces can be made without code input, and analogue-style and digital options are available for meter style selection.
• Input Ranges: Choose a multipurpose or multifunction meter with appropriate ranges for your system. For higher currents, you'll typically use current transformers (CTs). Auto-ranging can also be a useful feature.
• Communication Capabilities: Common communication protocols include RS-485 with Modbus RTU, Ethernet with Modbus TCP, and BACnet. For industrial panel meters, having remote monitoring and control capabilities is also a plus.
• Data Logging and Memory: Multifunction meters with internal memory will allow you to conduct trend analysis and identify anomalies. This feature is crucial for performance monitoring and troubleshooting.
• Programmability and Customisation: Programmable panel meters allow customisation of display parameters, units, and alarm settings. This provides greater flexibility in adapting the multi functional meter to specific needs.
• Environmental Protection: Look for a suitable IP rating (Ingress Protection) for dust and moisture resistance. This ensures reliable operation in harsh conditions.
• Operating Temperature: Consider the range of temperatures within which the meter will operate accurately. Typically, temperature ranges from -40°C to +80°C.
• Alarms and Control Outputs: These can be used to trigger external devices based on measured values, enabling automated responses to changing conditions.
• Certifications and Compliance: Look for certifications like MID, CE, UL, EAC, and IEC. This is especially important for industrial panel meters as it ensures that the meter meets required safety and performance standards.
• Power Quality Analysis: Some meters can measure harmonics, voltage sags, swells, and transients. This is useful for identifying power quality issues in the electrical system.

What Are Programmable Panel Meters?

Programmable panel meters are advanced multi-function meters that allow users to customise their functionality and display settings. They offer greater flexibility compared to non-programmable panel meters, enabling users to tailor the meter's operation to their specific needs and applications. This customisation can include setting alarm thresholds, configuring display units, and defining data logging parameters.

Programmable Panel Meters vs. Standard Panel Meters

Programmable panel meters offer several advantages over standard panel meters:

• Customisation: Programmable meters allow for greater customisation of display parameters, measurement units, and alarm settings, enabling users to tailor the display to their needs.
• Flexibility: They can be adapted to various applications and measurement needs, providing greater versatility in different settings.
• Data Logging: Many programmable meters offer data logging capabilities, allowing for the recording and analysis of historical data, which can be valuable for troubleshooting and performance analysis.
• Control Capabilities: Some programmable panel meters can also perform control functions, such as triggering alarms or controlling external devices based on measured values, enabling automated responses to changing conditions.
• Complexity and Setup: Programmable meters may require more complex setup and configuration compared to standard meters due to their advanced features and customisation options.
• Cost: Programmable meters are typically more expensive than standard meters due to their advanced features and capabilities.
• Applications: They are often used in applications requiring data logging, custom displays, or control functions, where greater flexibility and functionality are needed.
• User Interface: Programmable panel meters usually have more advanced user interfaces and displays for configuration and operation, providing a more user-friendly experience for customisation.
