Understanding MCERTS: The UK's Environmental Monitoring Standard
MCERTS (Monitoring Certification Scheme) is the UK’s formal certification standard for environmental monitoring equipment and services, introduced by the Environment Agency (EA). This certification ensures that instruments and services used in monitoring emissions, pollutants, and discharges meet rigorous standards of performance, quality, and reliability. For industries operating within the environmental sector, MCERTS plays a crucial role in ensuring that environmental monitoring is carried out accurately and consistently.
MCERTS is a cornerstone of environmental monitoring in the UK, ensuring the reliability of data across industries. By certifying both equipment and services, MCERTS provides assurance that monitoring meets the highest standards. For businesses, adopting MCERTS-certified solutions demonstrates a commitment to environmental protection, regulatory compliance, and operational excellence. Whether it’s in water, air, or soil monitoring, MCERTS remains a key component in achieving sustainable industrial practices and protecting natural resources.
The Importance of MCERTS
In many sectors, such as water management, industrial emissions, and air quality monitoring, precise and reliable measurement data is critical for regulatory compliance and environmental protection. MCERTS provides a robust framework that ensures this data meets strict quality criteria. It is especially important for companies that need to demonstrate compliance with environmental legislation, such as the EU’s Water Framework Directive or the Industrial Emissions Directive.
MCERTS-certified equipment helps reduce the risk of inaccurate measurements, which can lead to violations of environmental permits or standards, potential fines, and harm to the environment. By adhering to MCERTS, Nivus show a commitment to best practices in environmental monitoring, enhancing both environmental and operational credibility.
MCERTS Certification for Equipment
MCERTS certification is awarded to a wide variety of monitoring equipment, such as:
• Air quality monitoring devices: Equipment used to measure airborne pollutants from industrial sites or emissions.
• Flow monitoring devices: NF750 Flow Transmitter
• Water quality analyzers: Devices that measure pollutants or chemical concentrations in water bodies.
The certification process involves rigorous laboratory and field testing to verify that the equipment delivers accurate and reliable data under varied operational conditions. For instance, flow measurement devices used in water and wastewater management must demonstrate they can accurately measure flow rates under full, partial, or variable flow conditions.
NIVUS > MCERTS for Closed and Open Pipe Flow Measurement

Cross Correlation Technology by Nivus: The Ultimate Solution for Challenging Flow Measurement
In the realm of flow measurement, accuracy and reliability are paramount, particularly when dealing with challenging conditions such as turbulent flows, variable pipe fills, and changing fluid properties. NIVUS, a leader in innovative measurement solutions, has developed its patented Cross Correlation technology to tackle these challenges effectively. This article explores why Cross Correlation technology is the ultimate choice for measuring flow under demanding circumstances.

Understanding Cross Correlation Technology
Cross Correlation technology is a sophisticated measurement method that analyses the time delay between two signals to determine flow velocity. Unlike traditional flow measurement techniques that rely on direct pressure or electromagnetic sensing, Cross Correlation evaluates flow dynamics by comparing two distinct patterns in the flow, using sensors capable of profiling the entire water column.
This method provides precise flow measurements even in turbulent or fluctuating conditions, making it particularly beneficial for a range of applications, including wastewater treatment, industrial processes, and water resource management.
