What is multifunction meter? This article will introduce it from development history, definition, working principle, applications, how to choose, where to buy, etc.
In the early 1920s, Donald Macadie invented the first multi-function meter consisting of voltage, resistors, sockets, and switches for selecting ranges and a moving coil meter. As user needs change, multi-function meters have gradually evolved from simple analog to digital multifunction power meters, and now to industrial multifunction meters with multiple functions such as measuring various electrical automation parameters. In addition to integrating the functions of meter measurement, transmitters, and PLC, multi-function meters can also customize power quality and control functions according to user needs.
The real-time voltage and current on the line are coupled by high-precision mutual inductors, and after being sampled by the sampling circuit, they are sent to the energy metering IC for processing and conversion into electrical energy. Then, they are sent to the MCU through pulses, and different data calculations are completed according to the pre-set settings, and corresponding processing is performed respectively. At the same time, various power parameters are presented on the LCD screen through the driver and transmitted to the DI or DO to trigger the alarm function.
On one hand, the multifunction power meter is widely used for LV & MV switchgear, motor control centers, control panels, Genset panels, power distribution panels, Ring main units, photovoltaic grid-connected cabinets, and so on. On the other hand, many industries need these multifunction meters such as Power systems, power plants, petrochemicals, steel, metallurgy, coal mines, ports, rail transit, buildings, wind power plants, photovoltaic power stations, semiconductors, hospitals, data centers, transportation buildings, new energy, etc.
The work of multi-function meters and electrical components is realized through signal output and reception. The most common way is to transmit the measurement data to control equipment such as a computer or PLC through a communication interface to realize real-time monitoring and processing of data. At the same time, the multi-function meter can also directly output control signals to drive various electrical components to operate. It plays an important role in equipment operation management and safety assurance and can help users effectively grasp equipment status and performance, detect and deal with faults in time, and improve production efficiency and quality.
Regardless of the application, various factors need to be considered when choosing the right multi-function power meter. Here are some important considerations:
1. Confirm the specific needs of your industry
Different applications have different functional requirements for MFM meters, so you need to confirm your functional requirements, monitoring parameters, output types, etc. Do you need real-time power and power parameter measurement, energy metering, power quality analysis, control functions, or all of the above functions? Contact us to customize your multifunction meter.
2. Modular solution
Do you need to use additional modules to add more functions? If so, choose a multi-function meter with scalability to make it compatible with other devices.
3. High-precision measurement
The accuracy level of the multi-function meter can reach 02.s or 0.5s. How to determine whether the multifunction energy meter is a high-precision measurement? Through MID, CE, UL, EAC, IEC850, ANSI C12.20, and other certifications, you can know whether the multi-function meter meets the high-precision measurement standards. For example, ANSI C12.20 requires a multi-function meter to have an accuracy of 0.2s. ANSI C12.20 Class 0.2 high-accuracy meters that can monitor more than 400 measurement parameters are essential to protecting sensitive equipment and ensuring that facilities operate at peak efficiency. Read this guide to know our energy meter accuracy.
