A new fl ow computer? Exactly. The brand new AccuMind® is much more than only ‟one more fl ow computer”. It offers signifi cantly improved and advanced features at the price of a conventional fl ow computer.
The list of already established as well as novel features and functions includes:
But the AccuMind® offers even more. With its comprehensive interface concept it opens up new possibilities not only for the fl ow measurement, but also for their inspection and maintenance.
■ ... Calculation of properties of water and steam according to IAPWS-97;
■ ... Calculation of the properties of gaseous media (density, viscosity, speed of sound, heat capacity etc.);
■ ... Calculation methods for natural gases according to international standards (AGA-8 (DC/GC), SGERG-88, AGA-NX 19, ISO 20765-1 combined with AGA-3, AGA-5, AGA-7, AGA-10, AGA-11);
■ ... Support for a wide range of flow sensors (differential pressure based primary elements, volume and mass flow meters, turbines, ultrasonic, vortex etc.);
■ ... Increased accuracy for primary elements (orifice plates, venturi, nozzles etc.) by elimination of linearity errors;
■ ... Operate your flow sensor even at flows outside of calibrated limits and increase accuracy due to digital communication;
■ ... Store and renew calibration data for your flow sensor inside the AccuMind®;
■ ... Free configurable capacitive touch screen display offers a robust and aging-resistant interface for the user.
