The THERMAG Valve CS611 by ISOIL Industria has recently obtained MI-004 certification (in compliance with the Measuring Instruments Directive 2014/32/EU), confirming its role as a reliable, accurate, and legally recognized instrument for thermal energy metering. In this article, we summarize the main advantages that make the CS611 a winning solution for designers, installers, and plant managers, and explain why obtaining MID certification represents an additional value.
A compact, versatile, and certified technology
The CS611 is the ideal solution for thermal energy control and accurate consumption monitoring, offering the following benefits:
- Simplified operation and cost reduction
The CS611 not only measures energy but also supports control strategies that maximize efficiency and indoor comfort.
It combines, in a single device, a two-way control valve and an electromagnetic thermal energy meter, replacing up to three conventional instruments. Its compact design significantly reduces both installation and commissioning times.
The device supports water and various water-glycol mixtures while maintaining a flow measurement accuracy of 0.8%, even in the presence of other additives. - Maximum versatility
The electromagnetic technology allows MID-compliant measurement not only of water but also of water-glycol mixtures of different types and concentrations, with a flow measurement accuracy of 0.8% of the reading, even when other additives (besides glycol) are present. In addition, thanks to compatibility with PT100, PT500, and PT1000 probes and its PN25 body, the CS611 is suitable for a wide range of applications, both in new installations and in system upgrades. - Energy efficiency
The CS611 supports up to seven control variables and contributes to the automatic hydronic balancing of systems, directly impacting energy costs and building sustainability. - System longevity and predictive maintenance
The CS611 enables advanced system diagnostics, anticipating malfunctions and allowing targeted maintenance interventions, thereby increasing system reliability and lifespan.
The MID certification obtained by the CS611 Thermag Valve translates into:
- Legal validity for consumption measurements
Measurements taken by the CS611 have legal standing: this reduces the risk of disputes in billing and ensures greater transparency. - Reliability and accuracy
The CS611 guarantees maximum measurement accuracy even with complex fluids. - European compliance and regulatory security
MID certification confirms the CS611’s compliance with European standards, making its integration into international projects and installations easier. - Competitive market advantage
MI-004 certification gives the CS611 a clear edge over non-certified devices, providing engineers, installers, and plant managers with a safe, precise, and fully compliant solution.
