CVS-R03 Constant Volume Sampler

The CVS-R03 is a complete constant volume sampling system that allows operators to dilute and sample exhaust gases generated by diesel or spark ignition engines under controlled conditions. The concept of CVS systems is long established and well regulated through standards and guidelines. The exhaust gas is diluted with dry filtered air (HEPA filters) to reduce its temperature and to avoid, at the same time, water condensation. A pump generates and maintains a constant diluted gas flow rate; this method allows operators to optimize the dilution factor in order to better control the temperature and the pollutant gases concentration and makes the system applicable for a wide range of engine types and sizes. The system can be supplied with up to 4 sampling bags for the dilution air and another 4 for the diluted gas. The CVS-R03 automatically performs a self-cleaning procedure before sampling in order to avoid contamination of the sampled gases; at the end of the test both the diluted gas and the dilution air can be sent to a gas analyzer.

All these key standard operations are performed by means of the user friendly software that also allows operators to collect and store all important operational data (temperatures, pressures, flows, volumes, etc)  which allows for post processing savings on easy to manage ASCII files. CVS-R03 is fully compliant to European and American regulations so it can be used both for development and homologation. A complete remote control is available by means of RS232 or TCP/IP line using standardised AK protocols. 

No vehicle homologation facility is complete without a CVS system and the Control Sistem CVS-R03 builds on the very best practices and design developments of the last 20 years.
