Using Micro Motion patented MVD (multivariable digital) technology, the system delivers gas measurement data in compliance with API MPMS Chapter 21.1, and in accordance with AGA8-92 world standards. The Micro Motion 3711 gas flow computer combines a sophisticated flow computer with the user’s choice of Micro Motion Coriolis meters, enabling flow measurement of any pure gas or gas mixture with a total uncertainty of less than 0.5%. Because Micro Motion Coriolis measurement makes possible a large flow range, and is accurate across a wide spectrum of process and ambient conditions, one Micro Motion 3711 device can replace banks of meters of differing sizes and narrower ranges, says the vendor.
