Steam Flow Measurement

Steam Flow Measurement Measuring Steam Energy Evaluating Important Design and Installation Considerations Overview of Current Technologies Bowen Ierna ONICON Incorporated Clearwater, FL Measuring Steam Energy Velocity (ft/s) Volumetric Flow Rate (ft3/m) Internal area (ft2) density (lb/ft3) Mass Flow Rate (lb/hr) Energy Rate (Btu/hr) Enthalpy (Btu/lb) Basic steps for the Steam energy calculation Steam is a compressible fluid density is a function of both temperature and pressure Saturated Steam : Temperature and pressure are dependent variables. density can be calculated by measuring one variable. Superheated Steam : Temperature and pressure are independent variables. You must measure both to calculate density to measure mass flow and energy.

Micro Motion® ELITE® Flow and Density Meters 5 Liquid flow performance Mass Volume(1) (1) Specifications for volumetric flow rate are based on a process-fluid density of 1 g/cm 3 (1000 kg/m3). For fluids with density other than 1g/cm3 (1000 kg/m3), the volumetric flow rate equals the mass flow rate divided by the fluid’s density.
