Gefran Multi Function Panel Meters

A panel meter is an instrument used to display measurements from various industrial processes. Traditional panel meters typically display a single parameter using analogue needles or simple digital readouts. However, multifunction panel meters offer a more modern and versatile solution. These devices feature digital touch-displays and often include programmable interfaces, for customising the display of multiple parameters and input signals.

The Functions of Multifunction Panel Meters

Multifunction panel meters are versatile devices used by technicians and engineers to monitor and control processes. They offer a range of functions, including measuring multiple parameters like voltage, current and temperature, displaying data in various formats and providing alarms for critical values. These compact, programmable meters find applications in diverse settings — from factory automation and building management systems, to energy monitoring and generator control — improving efficiency and safety.**

Panel Meter Types**

There are numerous types of panel meters available, with each one designed for specific measurement needs and applications:

Analogue Panel Meters

These traditional panel meters use a moving pointer or needle to indicate the measured value on a graduated scale. While simple and cost-effective, they offer lower accuracy and resolution compared to digital meters.

Digital Panel Meters

Digital panel meters provide a numerical display of the measured value, offering higher accuracy and resolution than analogue meters. They are available in various configurations, including single-function and multifunction meters.

Multifunction Panel Meters

These versatile digital panel meters can measure and display multiple parameters simultaneously, such as voltage, current, frequency and temperature. They often feature programmable displays and communication interfaces for enhanced functionality.

Bar Graph Panel Meters

Bar graph panel meters visually represent the measured value using a series of LEDs or a bar graph display. They provide a quick and intuitive way to visualise trends and deviations from setpoints.

Temperature and Process Panel Meters

These panel meters are specifically designed to measure and display temperature from various sensors, such as thermocouples and RTDs. They may also display other process variables like pressure or flow.

Large Display Panel Meters

Featuring oversized displays for enhanced visibility, large display panel meters are suitable for applications where readings need to be seen from a distance.

Totalizer Panel Meters

Totalizers accumulate and display the total value of a measured quantity over time, such as the total flow volume or energy consumption.**

Key Features of Multifunction Meters **

Multifunction panel meters are designed to provide accurate and reliable measurements while withstanding diverse operating conditions, with some key features including:

Display Versatility: Digit heights can range from a compact 7mm to a highly visible 101mm, catering to different viewing distances and panel layouts.

Benefits of Using Panel Meters

Panel meters provide valuable benefits for monitoring and managing processes, such as:

Enhanced Readability: Panel meters present data in a clear and easy-to-read format, reducing the risk of errors and improving response times in critical situations.
Improved Accuracy: They provide accurate and real-time measurements of various process parameters, ensuring reliable data for informed decision-making.
Increased Efficiency: By providing insights into process variables, panel meters help optimise operations, leading to increased productivity and reduced downtime.
Enhanced Safety: Panel meters can be equipped with alarms and alerts, notifying operators of potential issues and contributing to a safer working environment.
Versatility: With customisable features and diverse functionalities, panel meters adapt to various applications, from simple monitoring to complex control systems.

How to Use Multifunction Panel Meters

Multifunction panel meters are designed for ease of use, offering intuitive interfaces and customisable features. Here's a basic guide to get you started:

Installation: Mount the meter securely into your panel using appropriate hardware. While they can be used with current transformers (CTs) to measure high currents, CTs are not required for installation.
Configuration: Most meters have user-friendly interfaces for programming and configuration. You can select your preferred display style (bar graph, analogue-style, or digital) and personalise it by adjusting text, colours and input scaling.
Saving Settings: Once configured, save your settings to both the meter and your computer to ensure data backup and easy recovery.
Operation: With the meter powered and connected to your system, it will begin measuring and displaying the selected parameters in your chosen format. You can monitor the readings and utilise any additional features, such as alarms or data logging, as needed.

Industrial Applications of Process Panel Meters

Process panel meters — particularly multifunction meters — find wide-ranging applications in various industries due to their versatility, accuracy, and ability to monitor multiple parameters:

Manufacturing and Automation: In manufacturing plants, process panel meters monitor critical parameters like temperature, pressure and flow rate in real-time. This data allows operators to monitor processes, ensuring product quality and preventing equipment malfunctions.
Energy Management: In buildings and industrial facilities, panel meters track energy consumption, voltage, current and power factor. This data helps identify areas for energy savings and optimise energy usage.
Water and Wastewater Treatment: Panel meters monitor water quality parameters such as pH, conductivity and turbidity in treatment plants. They also track flow rates and tank levels, ensuring efficient and safe operation.
Oil and Gas Industry: In oil and gas production and processing, panel meters monitor critical parameters like pressure, temperature and flow rate in pipelines, storage tanks and refining processes.
**HVAC Systems: **Panel meters are used in heating, ventilation and air conditioning systems to monitor temperature, humidity and air quality, ensuring optimal comfort and energy efficiency.
Pharmaceutical Industry: To maintain product quality and sterility in pharmaceutical manufacturing, precise monitoring of critical process parameters like temperature, pressure and flow rate is essential, a task for which panel meters are well-suited.
Food and Beverage Industry: Throughout processing, storage and transportation, panel meters play a key role in the food and beverage industry, ensuring food safety and quality by monitoring temperature, humidity and other crucial parameters.
Machine Monitoring: For predictive maintenance and preventing costly downtime, panel meters can be integrated directly into machinery, providing a display of operational data such as speed, vibration and operating hours.

How to Choose the Right Panel Meter

Selecting the appropriate panel meter requires careful consideration of several factors, to ensure it meets your specific requirements:

Type of Measurement: Determine the type of measurement you need to display, such as voltage, current (with ammeters frequently applied in this regard) temperature or frequency.
Accuracy and Resolution: Consider the required accuracy and resolution for your application. Higher accuracy and resolutions are essential for critical measurements where precision is paramount.
Display Type and Size: Choose a display type that suits your needs, such as analogue, digital or bar graph. Consider the digit size and viewing distance to ensure clear visibility.
Input Signal and Range: Ensure the panel meter is compatible with the input signal and range of your application. This includes factors like voltage levels, current ranges and sensor types.
Environmental Conditions: Consider the operating environment, including temperature, humidity and potential exposure to dust or moisture. Choose a panel meter with an appropriate ingress protection (IP) rating.
Cost and Value: Balance your budget with the required features and performance. Consider the long-term value and reliability of the panel meter.

Installation and Setup of Multifunction Panel Meters

Installing a multifunction panel meter is typically a straightforward process:

Safety First: Always disconnect power to the panel before starting any electrical work.
