Sierra's multivariable InnovaMass 240i steam mass flow meters measure up to five process variables with one process connection: volumetric flow rate, mass flow, density, pressure, and temperature. The 240i steam mass flow meter gives true mass flow by compensating for temperature and pressure variations, which is ideal for highly accurate steam flow measurement. Maximize your steam productivity and lower your cost of ownership. Our vortex flow meters are also ideal for volumetric flow of water. Ideal for pipe sizes from 1.0 to 8.0 inches (DN25 to DN200); ideal for saturated or superheated steam, gas, and liquid applications; mass and/or volumetric flow rate; Complete suite of digital communications.
