No More HOT Work Permits! Certified Portable Gas Flow Metering in Hazardous Areas

The FLUXUS G608 portable gas flow meter is based on the widely used, highly reliable and versatile G601, but has been specifically engineered for its use within hazardous areas and is covered by ATEX, IECEx and FM certification.

It is the ideal solution for gas flow measurement in potentially explosive areas, may it be for a temporary replacement of a stationary flow meter, check metering or service operations. Due to its certification, users are not anymore obliged to obtain a Hot Work Permit, making the access to ATEX, IECEx and FM Zones much easier and less time consuming.

Offering a high degree of flexibility, without compromising on Safety!

The extremely resistant carbon fiber housing, together with the rugged transducer design, ensures a high impact protection as well as resistance against oil, water and many other liquids. The G608 portable gas flow meter shares the same efficient battery management as the G601, offering over 14 hrs. of remote measurement time.

Moreover, the measurement system can be fully set-up in a few minutes due to the intuitive user guidance and the automatic transducer recognition. Its application range is unrivaled - from pipes as small as 6 mm up to 2100 mm inner diameter and temperatures ranging from -40°C to 100°C.

The G608 gas flow meter goes where other portable devices can't

Being equipped with two flow channels, multiple Inputs and an integrated data logger with a serial interface, the portable gas flow meter is designed for direct usage in demanding environments, such as in the Upstream, Midstream and Downstream area as well as in the chemical and processing industries.

As known from all FLEXIM flow meters, also the G608 features a highly precise bi-directional measurement at fast and even very slow gas flow rates over a wide dynamic measurement and pressure range and is not prone to temperature and zero drift, being fully compliant to ANSI/ASME regulations.

However, the G608 is not only safe, accurate and reliable, but also very compact and lightweight, offering the user to even carry the complete measuring system as personal luggage for offshore visits.

Additionally the G608 can also be used for flow measurement of virtually any liquid media. Fur further information please consult the Technical Facts of the F608 portable flow meter.
