The permanent Gas flow meter G709 - The Rack Version The FLUXUS® G709 gas flow meter is designed for permanent installation in 19" rack systems, with 2 flow channels and a flexible configuration of various inputs and outputs. Internally identical to the G704 stationary gas flow meter, its non-intrusive measurement technology ensures a precise bi-directional, highly dynamic gas flow measurement. As all other FLUXUS flow meters, the G709 features an automatic loading of calibration data and transducer detection to reduce set-up times and to provide precise, long-term stable results. Transducers are available for a wide range of inner pipe diameters (1/4 to 63 inches ), dynamic gas temperatures (-40°F to 390°F) as well as hazardous areas and are resistant to dust and humidity. The measurement is unaffected by the gas density, viscosity and composition as well as dust, humidity, temperature or pressure. With its wide range of electrical inputs and outputs, the G709 gas flow meter can handle a variety of process parameters within gas flow metering applications.
