The Venturi gas meter utilized adheres to ISO 5167 standards, ensuring precision and reliability in flow measurement. This particular gas meter offers numerous advantages over alternative systems. It exhibits long-term stability in measurements, is adaptable to various weather conditions, and demonstrates reduced susceptibility to contamination due to its self-cleaning profile. Furthermore, its design eliminates components sensitive to air contact, enhancing durability and accuracy.

ECHO HV EPA stands out as a unique instrument in flow measurement and regulation due to its ability to adjust to real-time conditions without requiring recalibration. This flexibility extends to the user’s ability to interchange sample heads and adjust flow rates seamlessly. Equipped with a three-stage brushless blower, the ECHO HV EPA ensures virtually maintenance-free operation, boasting an average lifespan exceeding 20,000 hours, equivalent to over two years of continuous operation.

The instrument provides two sampling inlets: PUF and TSP, both freely interchangeable to suit specific sampling needs. The PUF sampling module, featuring a 102 mm filter holder and a 58 x 125 mm adsorbing cartridge (compatible with PUF or XAD2), enables simultaneous sampling of particulate and gas fractions at flow rates ranging from 180 to 220 l/min. Alternatively, a filter holder for total particulate (TSP) on a 150 mm diameter membrane is available, accommodating flow rates of up to 500 l/min.
