FLUXUS® ADM 7907 - permanent installation in 19" rack systems

The FLUXUS® ADM 7907 is the 19" inch rack version of the highly versatile FLUXUS ADM 7407 liquid flow meter.

Internally identical to the FLUXUS ADM 7407, its non-intrusive measurement technology ensures a precise bi-directional, highly dynamic flow measurement over a wide turndown ratio. As the transducers (available also as ATEX and FM approved versions) are mounted on the outside of the pipe wall and are enclosed in the stainless steel VARIOFIX mounting fixtures, the system does not suffer from wear and tear or clogging, can't be a risk for leaks and will not cause any pressure drops inside the pipe. The transmitter itself, as a Rack version, can be situated in a control cabinet at quiet a distance from the actual measurement point and will be connected through junction boxes.

Due to its matched and paired transducers as well as the internal temperature compensation (compliant to ANSI/ASME regulations), the measurement system is drift free and zero stable ensuring highly accurate readings. Moreover, as the transducer calibration data is automatically loaded by connecting the transducer to the transmitter the set-up times are significantly reduced.

As of its exceptional dual-uP technology, the high number of measuring cycles per second and the adaptive signal processing, the FLUXUS® ADM 7907 flow meter produces stable and reliable measuring results even under difficult conditions.

 

For all pipe characteristics and temperatures

The ADM 7907 liquid flow meter can be applied at inner pipe diameters ranging from 6 mm up to 12 m (no limitations on pipe wall thickness or material) and media temperatures from -40°C up to 200°C (-160° up to 400°C with the WaveInjector mounting fixture). The measurement is pressure independent and can take place on pipes of almost any material and on almost any liquid.

With up to two measurement channels, the FLUXUS ADM 7907 permanent liquid flow meter can also be applied to difficult measurement points and is completely unaffected by viscosity, composition and toxicity of the medium itself as well as dust and humidity on the pipe wall outside.

Further, with its wide range of electrical inputs and outputs, the FLUXUS ADM7907 flow meter can handle a variety of process parameters within liquid flow metering applications. Input quantities such as temperature and/or pressure can be used by the flow meter, together with the measured flow, for the calculation of further quantities like thermal energy / BTU, mass flow rate, density, etc.
