A direct counter is a type of electric energy counter that directly measures the amount of electric energy consumed by a load.

In contrast, a three-phase meter measures the electrical consumption of three electrical circuits simultaneously. It is used in industrial and commercial electrical installations, where a large amount of electrical energy is consumed. The three-phase meter consists of three measuring devices and a recording mechanism for each of the electrical circuits. It can measure the voltage and current of each phase, as well as the active and reactive power, allowing for monitoring of the quality of the electrical supply.

Modbus energy meters are widely used in electric energy monitoring and control applications, particularly in commercial buildings, factories, power plants, wind turbines, and solar installations. The data collected by Modbus energy meters are often used to optimize energy usage, identify bottlenecks, and reduce energy costs.

The Measuring Instruments Directive (MID) 2004/22/EC is a regulation that applies to the production of measuring instruments, particularly those used for water metering. It establishes performance and marking requirements for meters to harmonize billing rules. Additionally, the MID directive imposes design constraints to ensure the meters are tamper-proof and prevent fraud. Only MID-compliant meters with the CE marking are authorized for billing the consumption of water and energy.

A single-phase meter is an electric energy meter that measures the electrical consumption of one electrical circuit at a time. It is often used to measure electricity consumption in households and small businesses. A single-phase meter consists of a measuring device and a recording mechanism, which records the amount of electrical energy consumed over a given period of time.

When selecting an energy meter, it is important to take into account several factors to ensure that the selected meter is suitable for your needs:

It can be used for three-phase or single-phase power grids, depending on the type of counter chosen. Direct counters can be used to measure the energy consumption of all types of installations: residential, commercial, or industrial.

A Modbus energy meter is a type of electric energy counter that can communicate with other devices using the Modbus communication protocol. The Modbus protocol is a serial communication protocol that allows devices to communicate with control and monitoring equipment using an RS-485 or Ethernet serial cable.

In summary, the main difference between a single-phase meter and a three-phase meter is the number of electrical circuits they can measure simultaneously. The single-phase meter measures the consumption of one electrical circuit, while the three-phase meter measures the consumption of three electrical circuits.

The current transformers (CTs) are integrated into the product and therefore require no accessories. It is sufficient to wire each of the phases downstream of the protection (circuit breaker or fuses) to the counter and then connect the equipment under the counter.
