FLUXUS® F709 - permanent installation in 19" rack systems

The FLUXUS® F709 is the 19" rack version of the highly versatile FLUXUS F704 liquid flow meter.

Internally identical to the FLUXUS F704, 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 VARIOFIXmounting 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.

Further, with its wide range of electrical inputs and outputs, the FLUXUS F709 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.
