The Rosemount 3051S MultiVariable Transmitter is a best-in-class solution customized to obtain measurement combinations of differential pressure, static pressure and process temperature. This multivariable transmitter is a cost-effective device that reduces pipe penetrations, impulse piping and connection systems. This device is also engineered with built-in flow calculations for fully compensated mass flow measurements.
To achieve the most accurate flow measurement, differential pressure, static pressure, and process temperature must be accounted for.
• Measuring only differential pressure can result in >6% error due to density changes.
• Adding static pressure measurement helps reduce error to <3% but temperature still affects mass flow.
• The addition of process temperature can reduce error down to <1%.
Taking each one of these three measurements separately involves complex calculations and multiple devices.
The Rosemount™ 3051S MultiVariable™ Transmitter measures differential pressure, static pressure, and process temperature in a single device while dynamically calculating mass flow 22 times per second within the transmitter.
The transmitter’s ability to internally calculate fully compensated mass flow improves accuracy and reduces measurement uncertainty and complexity. This multivariable design also reduces pipe penetrations, impulse piping, and connection systems for additional cost savings.
