Differential Pressure Flow Measurement in Steam
Reduce Operating Costs and Project Cycle Time in Steam Flow Measurement
Accurately Measure Steam Flow Applications
The Rosemount 3051SFA Annubar Flow Meter is engineered with built-in flow calculations for fully compensated mass flow measurements and meets National Standards of steam calorific measurement. The instrument measures differential pressure, static pressure, and process temperature in a single device while dynamically calculating mass flow 22 times per second within the transmitter.
Additionally, the Rosemount 3051SFA eliminates impulse lines, thereby simplifying installation and reducing potential leak points. Rosemount Annubar flow meters measure multiple variables and are engineered with an integrated thermowell for temperature measurement. Its patented T-shaped sensor is capable of obtaining measurements via a single pipe penetration while maintaining a small profile in the pipe to reduce permanent pressure loss and increase energy savings.
