Two versions are supplied by Orimaster, one for volumetric flow and one for mass flow. It has an integrated DP flow measurement system that combines primary element with DP transmitter in a single flow meter assembly. The one piece flow meter is pressure tested as an assembly has improved its reliability with no leaks to trace and rectify. There are no impulse piping installations required in the integral impulse connections and can provide repeatable DP connection across installation locations. The integral multi-variable transmitter and RTD for direct reading of gas mass and corrected volume flow rates in a single unit.
