2008-08-25 - ABB’s new variable area flow meter with its electronics offers intuitive operation which is readily comparable to modern cell phones. It can easily be configured at the meter site without resorting to any written instructions.
The FAM540 series offers flexibility as it is based on a modular system offering flow meters with a simple indicator or including an advanced electronic transmitter. The combination of the various models with the different indicators provides suitable flow solutions for each application and all industry sectors.
Externally the new instrument generation is immediately noticeable by the greatly improved readability of the display with the four button operator keypad and new Ex-approvals. Hidden behind these features is the ABB philosophy, to offer the user instrumentation products which provide a common and up-to-date interface for operating their pressure and temperature instruments as well as their flow meters.
All indicators have an excellent instrument read out because the needle’s vibrations are substantially minimized.The comfortable operation via the graphical display allows a simple adjustment to changing operating conditions.
The ease of configuration opens up the ability to adapt the instrument at the site for the specific application needs, such as changes in the operating conditions; fluid density, temperature and/or pressure. The function assigned to the integrated contact output (alarm status, pulse output) is controlled from the software.
The instantaneous flow rate and the totalizer values are simultaneously indicated on the 4-line graphic display. Instruments without a display, but with a current output, can be configured using HART Communication on a Handheld or DTM.
The proven advantages of the previous FAM5400 models including application based flow features (Multifloat-System), which regularly apply swirl reduction for damping the indicator noise or the wide temperature range limits remain intact.
The use of variable area flow meters in industrial process measurement has been established for more than 70 years. Their measuring principle is both technically mature and cost-effective. They feature an amazing design variety and high reproducibility and do not require an external power supply for measured value indication on-site. As a result, they are the appropriate solution for almost all applications involving the measurement of liquids, gases or steam.
