In Germany and many EU countries, the operation and accuracy of water resource and wastewater monitoring systems are determined by the following standards and national regulations:
- MCERTS
- UBA
- TÜV
- WMO
Compliance with UBA and TÜV (Technical Inspection Association) requirements involves rigorous suitability testing of automated measuring systems. Meanwhile, the MCERTS (Monitoring Certification Scheme) certificate confirms the reliability of continuous, online water monitoring devices for use in industrial and municipal wastewater.
Compliance with these standards is used in the German regulatory environment as the technical basis for wastewater monitoring and is linked to the requirements of the AbwV (Effluent Ordinance). Therefore, their application in Georgia's technical regulations is advisable as a criterion for verifiable quality and data reliability.
Additionally, TÜV/UBA is specifically required for systems that perform automated reporting to environmental authorities. It verifies that automated systems provide measurements equivalent to manual measurement methods in accordance with DIN/ISO standards.
The World Meteorological Organization (WMO) No. 8 Standard (Guide to Meteorological Instruments and Methods of Observation) serves as the global technical foundation for environmental monitoring.
The WMO No. 8 standard defines sensor methodology and technical specifications essential for analyzing long-term climate and environmental trends. This guarantees consistent and high-quality data collection in hydrology and meteorology.
Regarding ISO 748, it is a hydrometry technical standard that regulates liquid flow measurement in open channels.
The integration of WMO No. 8 and ISO 748 standards into the German regulatory environment occurs through LAWA-Pegelvorschrift (Water Level Measurement Instructions). LAWA instructions define the data quality mandatory for federal and regional monitoring networks.
Possession of these standards confirms that these companies' sensors meet high-accuracy classes—typically with an error of < 0.05% Full Scale (FS)—which is required for official German hydrometric accounting.
To meet the demands of German state authorities, companies must align their data acquisition, calibration, and standard operating procedures with ISO/DIN standards, with ISO 748 serving as one of the main pillars.
Collectively, these authoritative environmental and technical organizations establish a regulatory and technical framework that sets national environmental requirements (UBA), imposes strict standards on monitoring devices (MCERTS), ensures independent verification of safety and quality by an authoritative body (TÜV), and establishes international standards for the accuracy of hydrometeorological measurements (WMO).
