Why Use Coriolis Technology For Precision Gas Measurement? Because Coriolis Meters Measure: Direct Mass Flow Rate Temperature and pressure measurements are not required for fluid calculations Flow computers are eliminated High Accuracy Mass flow accuracy of ?.5% 켣S for turndown up to 100:1 Gas density measurement accuracy of ?.002 g/cc No Calibration Shift with Changing Density or Gas Properties Micro Motion factory water calibration accurately transfers to gas Measurement accuracy verified by independent testing at gas pressures from 25 to 1450 psia

Why Use Coriolis Technology for Precision Gas Measurement? Because Coriolis Meters are: Independent of Flow Profile No straight run required Low Maintenance No moving parts, so no time dependent calibration shift Non-intrusive Multi-Variable Device Mass flow, density, temperature from one installed device Fewer potential emission points with a minimum of pipe breaks

Gas Proving - Sonic Venturi Testing Conducted at Colorado Engineering & Experimental Station, Inc. (CEESI) NIST Traceable Calibrations Compressed air used as calibration fluid Pressure range from 25 psia to 1450 psia Sonic venturis used as reference Stated lab accuracy = ?.5% of mass rate

Detail of Sonic Venturi If the pressure ratio between Pi and Patm is maintained above the 밹ritical ratio?then the velocity at the throat is equal to the sonic velocity of the gas (air) The throat area is known (measured) Pi and Ti are measured to calculate density Mass Rate = (Velocity) * (Area) * (Density) Pi Ti Patm Throat
