Predict the density of fluid, volumetric flow rate, and mass flow rate with this 2" (50 mm) meter that uses two flow meter technologies in combination: vortex and differential pressure. In addition, this allows fluid density to be found without information from an external source and provides several valuable outputs.
Predict the density of fluid, volumetric flow rate, and mass flow rate with this 2" (50 mm) meter that uses two flow meter technologies in combination: vortex and differential pressure. In addition, this allows fluid density to be found without information from an external source and provides several valuable outputs.
Capable of calculating the density of changing gas mixtures, this flow meter can calculate natural gas, steam service, and wet natural gas service. Also, with the addition of two differential pressure transmitters, advanced diagnostic software continually monitors and verifies the meter’s performance.
