Types of Energy Meters

Energy Meters are devices used to measure the electricity consumed by a home or industry for a certain period of time. They are also known as watt-hour meters.

They can be either electromechanical or electronic.

Electromechanical meters are the most common type of energy meter and work in a similar way to an electric motor. They make use of coils and gears that change magnetic fields as electricity passes through them. This creates a changing magnetic field in a metal disc that responds to the electric current being passed through it, thus showing the amount of electricity being used on a clock-like display.

In electronic meters, the electric current is sensed by circuitry that measures voltage and amperes. These are then converted into a digital signal.

This information is then stored in an EEPROM memory. It is then transmitted to a microcontroller which acts as the brain of the system by performing all necessary functions such as storing data, operating the meter using buttons, calibrating phases, clearing readings; etc.

Most smart meters are capable of controlling the power in a facility, such as adjusting thermostats and turning off appliances. This allows you to control your energy usage and save money on bills.

They can help detect power quality issues by detecting voltage and frequency fluctuations that may be negatively impacting your equipment. This could potentially cause your equipment to break down or stop working altogether.

Some modern electric meters can even be used as probes to detect problems in your utility network. This is particularly important in areas where your business has a high level of dependency on the utility.

Other advanced meter types can help improve your facility's energy efficiency, and they can also allow you to take advantage of more time-of-use plans offered by your energy supplier. This can make your operation much more cost-effective and reduce your environmental footprint.

These types of meters can also be paired with other smart devices in your facility for more convenient and sophisticated control. For example, some meters can communicate with programmable logic controllers (PLC) or HVAC systems and can provide feedback about power consumption when a specific demand occurs.

In addition to measuring power in terms of kilowatts and joules, these meters also allow you to set different tariffs for your electricity usage. These can be useful for large businesses that require separate rates for peak, off-peak and shoulder times of the day.
