Rosemount™ 3051S MultiVariable™ Transmitter
The Rosemount 3051S MultiVariable Transmitter measures differential pressure, static pressure and process temperature in a single device. This multivariable transmitter is a cost-effective solution that reduces pipe penetrations, impulse piping and connection systems. It is also engineered with built-in flow calculations for fully compensated mass flow measurements. A wide variety of primary elements are available as assemble-to options for simplified installation and commissioning.
