The ADDAX multifunctional meters can be used as household meters, as well as meters for the small motor sector.
The ADDAX system supports up to 1,000,000 meters simultaneously.
The ADDAX system is capable of operating in two modes:
The system supports switching between these two operating modes during the operation of the meter.
Protection against theft of electricity is provided by the following means:
Multifunctional meters provide detailed information on consumption, including interval profiles that make it possible to control the quality of the supplied electricity, provide remote disconnection/activation of the load of the consumer and provide data to third parties for settlement with the consumer.
The main advantages of the equipment:
A split system is a division of a multifunctional meter into components: a metering part and a user part (remote display).
This method of separation allows you to install the metering part in hard-to-reach places, thereby making it difficult for theft of electricity or interference with the operation of the meter.
The metering part – a pole meter – is installed on power poles or specially fenced places.
The COSEM software is designed to demonstrate the operation of ADDAX devices.
The program allows you to perform the following functions:
The system includes:
SIMS is automated metering system for various types of resources (electricity, water, heating, gas) and consumption control.
Basic functions:
– communication statistics
– emergencies
– detailed consumption data
The system uses the technologies:
Basic advantages:
This is a modern automated system for remote metering and control of the consumption of various types of resources (electricity, water, heating, gas).
The system consists of three levels.
Upper level: collection, storage and processing of data and some data management elements (MDMS).
Middle level: equipment for providing data exchange with metering points.
Lower level: subscriber equipment installed directly at metering and control points.
The system supports a wide range of services: metering by time and load profile, load control, demand management, imbalance control, operation in a prepaid and credit mode.

Components within third-party companies’ responsibility include:
ADD Grup implements technical solutions based on STS standards that allow consumers to purchase water through a prepayment system.
To use water, the consumer acquires digital tokens, which are transferred to the water meter via an app on their smartphone. Once the tokens are depleted, the valve shuts off the water supply to the consumer. Such solutions are mainly used by utility companies in developing countries to mitigate the risk of non-payment for resources.
The smart Addra water meter promptly responds to emergency situations, records the information in an event log with a timestamp, and instantly transmits this information to the water supplier.
Emergency cases include:
The Addra water meter has received a certificate from the Czech Metrology Institute confirming its maximum protection against moisture and dirt. Test results proved that the degree of protection of Addra water meters complies with the international standard IP68.
The smart meter from ADD Grup was tested by the Czech Metrology Institute specialists at a depth of 4 meters for 48 hours. IP68 protection indicates that the meter’s casing is completely resistant to dust, moisture, and other external influences.
Nominal pipe diameter (pipe length): DN15 (110/165 mm) / DN20 (130/195 mm) / DN25 (190/225 mm).
Shut off valve functionality:
Various communication solutions are used to connect with the Addra water meter, depending on specific monitoring and water consumption management system needs and capabilities:
The main advantage of ultrasonic technology in the Addra water meter over mechanical technology lies in measurement accuracy and the ability to obtain a broader spectrum of water data.
Unlike mechanical meters, whose accuracy is typically limited by recalibration intervals (usually every 5 years), the accuracy class of ultrasonic water meters remains constant throughout their service life (up to 16 years). Addra ultrasonic water meters have no moving parts, making them more reliable and durable.
R is a parameter that determines the measurement range of the water meter. It is expressed as the ratio of the maximum flow rate Q3 (the flow rate at which the water meter operates correctly) to the minimum flow rate Q1 (the flow rate within allowable error limits).
The higher the value of the coefficient R, the larger the range over which the water meter measures the volume of flowing water. Increasing the coefficient R can be achieved by increasing Q3 or decreasing Q1. The lower the Q1, the higher the sensitivity of the water meter.
The minimum permissible pressure at the water meter’s outlet should be 30 kPa (0.3 bar).
To avoid damaging the water meter due to critical temperatures, the water meter should be operated in an ambient temperature range of +5 to +55°C.
The minimum temperature of the measured water is +0.1°C. When choosing a water meter, special attention should be given to the operating temperature. If the water meter is used improperly, it can be damaged.
