What is a digital panel meter
A digital panel meter is a device that accurately measures and digitally displays one or more electrical parameters. These meters are typically mounted on control panels and are used for a wide range of industrial and commercial applications.
Digital panel meter working principle
The digital panel meter working principle is to digitize analog signals. First, a built-in analog-to-digital converter (A/D converter) accurately converts received analog signals, such as voltage and current, into digital quantities and performs digital processing. Ultimately, these digitized parameters are clearly displayed on the digital panel meter’s display, allowing users to easily and accurately measure and monitor them. This digitization process fundamentally ensures high measurement accuracy.
Types of digital panel meters
Digital panel meters can be categorized based on various characteristics, as follows:
By Display Content: Depending on the richness of the information on the display, they can be divided into single-digit meters that display only numbers, and multifunction meters that can display both numbers and letters.
By Display Technology: Meters primarily utilize two display technologies: bright and clear LED (light-emitting diode) displays and lower-power LCD (liquid crystal display).
By Signal Input Type: Depending on the type of signal being measured, digital panel meters can be categorized as measuring AC current, AC voltage, DC current, DC voltage, and other types.
By Measurement Function: Depending on the number of parameters measured, they can be categorized as single-function meters that measure only a single parameter, and multifunction meters that can simultaneously measure multiple parameters, such as voltage, current, and power. Based on measurement function, Blue Jay digital panel meters can be divided into single-function digital panel meters and multifunction digital panel meters.
Blue Jay single-function digital panel meter
Our BPM2/3-96U digital panel meter is equal to a voltmeter, which is only used to measure voltage levels.

Our BPM2/3-96P digital panel meter is used to measure active power. Our BPM2/3-96Q is used to measure reactive power. These digital panel meters can be called a power meter that measures power consumption.
BPM2/3-96H digital panel meter is equal to a Power factor meter, which is used to measure power factor.
BPM2/3-96F digital panel meter is equal to a frequency meter. The frequency of an electrical signal is measured in Hertz.
Blue Jay Multi-function digital panel meter
We mainly offer four types of multifunction digital panel meters. Our BPM3-96UI is only used to measure voltage and current. BPM3-96UIF is used to measure voltage, current, and frequency. Our BPM3-96PQH is used to measure active, reactive, and power factor. Our BPM3-96E can measure full electrical parameters, including voltage, current, active/reactive power, power factor, frequency, and active/reactive energy.
What optional features are available for digital panel meters?
Digital panel meters may include many additional features to provide additional functionality. Some digital panel meters offer optional features such as setpoint options, alarms, on/off control, and adjustable displays. Blue Jay’s digital panel meters primarily feature an expansion module, including analog output, digital output, and energy pulse output.
Analog Panel Meters vs. Digital Panel Meters
Compared to analog panel meters, digital panel meters are generally more accurate, precise, and intuitive to read, and are unaffected by environmental factors. Furthermore, analog meters offer a number of optional features. Given these advantages, digital panel meters are often used in industrial automation, telecommunications, power distribution, and management. In industrial automation systems, digital panel meters are used to monitor and control various parameters, such as voltage and current. In telecommunications, they monitor signal strength, voltage levels, and other parameters. In power distribution systems, they monitor electrical parameters such as voltage, current, and frequency.
How to choose a digital panel meter?
Functional Requirements
Single Parameter: For example, measuring only voltage, current, and frequency.
Multi-Parameter: Comprehensive energy parameters such as voltage, current, active power, reactive power, power factor, and harmonics.
Accuracy Level
The instrument’s accuracy determines the reliability of the measured data.
Generally, the accuracy for voltage and current measurements is Class 0.5 or Class 0.2.
For energy metering with higher requirements, choose Class 0.2 or Class 0.5S.
Signal Input
Direct measurement: Suitable for low-voltage circuits.
CT/VT ratio input: Suitable for high-voltage or high-current circuits.
When selecting an instrument, confirm the CT/VT ratio range it supports to ensure compatibility with the on-site electrical parameters.
Dimensions
Common dimensions include 96×96 mm, 72×72 mm, and 48×96 mm. These dimensions must match the panel cutout dimensions of the distribution cabinet. The installation depth should also be considered to avoid insufficient space within the cabinet.
Communication Protocols
Modern digital meters often have communication capabilities, facilitating remote meter reading and monitoring:
Common protocols: RS485 Modbus RTU
Some products support CAN, Ethernet, Modbus TCP, and others.
Choosing the appropriate communication interface based on system integration requirements enables centralized data management.
Power Requirements
Common power supply specifications include: AC 220V / 110V, DC 24V / 48V / 110V
Confirm the power supply environment when selecting a meter to avoid instrument malfunction due to power mismatch.
