Gas Mass Flowmeters
Sierra designs and manufactures a wide range of gas mass flowmeters across three core technologies: capillary thermal, immersible thermal, and vortex technology.
Mass Vortex Flow Meters
Sierra’s mass vortex flow meters can be specified to measure up to five process variables with one process connection: volumetric flow, mass flow, density, pressure, and temperature. Vortex technology is ideal for steam flow measurement and volumetric water. Available in both inline and insertion versions, with easy hot tap feature for large steam pipes. Software apps make it easy to set up and tune your meter for your application.
