WHAT IS A POWER METER ?
It is one of the most useful tools for measuring electrical power.
The power meter device can measure voltage and current and show the amount of energy.
One of the most important features of the power meter is the accurate and fast
measurement of energy and its simple operation.
The multi-purpose power meter can calculate active power, reactive power, energy, voltage,
current and RF and measure optical signals. Power meter is used in electronic engineering
and calculating the electrical power of devices. Other energy measuring tools include
radiometers, photometers, laser power meters, and light meters. In this article, you will
read about the types and use of power meters.
Application of power meter:
Power meter is used to measure energy and power and is very efficient in industrial
environments.Power meter features include:
Inspection of the production line of electrical devices
Evaluation of high voltage equipment
Measuring the efficiency of industrial engines
Measurement of alternating current in electrical equipment
Evaluating the amount of electrical energy consumption of high-consumption devices in
homes or workshops and measuring the power of electric motors
Power meters are usually equipped with one, three or six measuring channels. They can
measure all parameters in alternating current or direct current systems such as apparent
power, active and ratio power, current, voltage, frequency, power factor, apparent energy,
active and reactive energy.
Button and simple power meters are among the first and most widely used; Of course,
nowadays with the advancement of technology, modern and touch power meters are also
used.Some of the more advanced systems can also be connected to a laptop or smartphone
through a web application; This makes things easier and remote monitoring.
The performance of the power meter is such that it evaluates the energy consumed in the
residence, electrical device or commercial company.
Kilowatt per hour is one of the most common units for measuring the amount of energy and
electricity consumed. The power meter also works on the bicycle and measures the output
power of the cyclist.
Advantages of using a power meter:
Measurement and evaluation of energy consumption
High consumption devices
Evaluating the amount of electrical energy of devices
Measuring the effective factors in energy consumption in order to control and reduce it
Simultaneous measurement of several parameters
Checking the cost of electricity consumption by a device
Avoid wasting energy
Types of power meters Familiarity with cycling power meter What is a cycling power meter?
Optical power meter: Optical power meter (OPM)
Cycling power meter was tested since 1980 to calculate power on racing bikes and was
marketed since 1989. These power meters provide the ability to evaluate and analyze
energy for cyclists.

hub. This device can transmit information and data to the subsidy attached to the bicycle. |
Optical fiber power meter or optical power meter in Farsi is used to measure the optical
power transmitted in optical fiber. It is used to measure power in optical signals and is used
in optical fiber systems. The optical power meter measures the power of the optical fiber of
the equipment or the power of the optical signal. This device consists of a calibrated sensor
and a display and is used to support, debug, and troubleshoot fiber optic networks.
It is very easy to install and use the optical power meter and it is used in WAN, LAN,
metropolitan network and long-distance optical network. Stability measurement, fiber
stability test, power measurement of active equipment, length measurement and patch cord
test are among the applications of optical power meter.
Microwave power meter:
A microwave power meter is used to measure electrical power at microwave frequencies
and has a head and a strong sensor that is connected to the calculation section through a
cable. This power meter receives the frequency through the sensor and shows the amount
of power.
This power meter is also used as an electricity meter and has a wide bandwidth. The
microwave power meter converts the microwave power into analog voltage and calculates
and displays the results. This device can be connected to the computer through USB

date.
This device can display several parameters at the same time and has the ability to measure
single integral power consumption, frequency and single phase sequence.
Panel power meters have LCD or LED displays that allow users to read three phase values
simultaneously.The brightness of the screen is such that the information can be read in
strong light and at different angles. One of the features of panel power meter is easy
installation, simple operation, ability to analyze power quality and record parameters with
Three-phase harmonic power meter:

To choose the right power meter, consider the following:
Application:
The three-phase harmonic power meter has the ability to test current and power and
consists of three channels including voltage, current and power. Harmonic power meter can
easily measure harmonic parameters, apparent power, frequency, active reactive power.
The USB power meter is an accurate and easy-to-use device for checking the performance of
all types of power banks, USB cables, data cables, and electronic equipment. This device is
connected to the output of the desired device through the input connection of the USB cable
and measures the amount of voltage, current and charging capacity.
The plug power meter is suitable for checking the energy consumption of electrical
equipment, which evaluates energy, voltage, current and frequency with an advanced
microchip.
The electric power meter calculates the energy consumption based on kilowatt hours and is
used in various places such as residential areas, industrial environments and workshops.
The electric power meter can check the maximum power in different time intervals and
help you save energy. These power meters have relays to reduce load usage during peak
periods.
This sensor has a photodiode that is used to determine the appropriate wavelength and
power level.
The power meter screen is set to display optical power and wavelength.Power meter
selection guide:
Optical power meters are designed for specific applications and can be used to measure
optical power quickly and easily. Before choosing a power meter, pay attention to its
application type.
Wavelength range and calibrated wavelength:
Measuring range:
Consider the critical range of signal power.
Interface type:
A patch cord is usually used to connect the device.
Power meters support a certain range of wavelengths, which is usually between 800 and
1700. It is better to calibrate the device on the wavelength of the power meter before
testing the optical power; This will calculate both the wavelength range and the calibration
wavelength.
A power meter or power meter is a device for calculating power, energy, voltage and
frequency that can measure several parameters at the same time.With the help of this
device, the amount of electrical energy consumption can be evaluated and energy
consumption can be optimized. It is also called power meter, ammeter and volt meter
