The Neftemer Multiphase Meter is a non-intrusive unit that is easy to install, requiring less time and skill than conventional assemblies. The unit supports phase fraction, velocity measurement and pattern recognition measurement categories. The unit has been tested on a wide range of oil types, and can readily handle even the heaviest oils. It has been tested for accurate measurement in temperatures ranging from -50^o to +50^o centigrade.
