The Rosemount 3051S Wireless is a best-in-class solution designed to deliver reliable data via a secure WirelessHART network. By providing direct differential and static pressure measurement alongside module temperature in one versatile device, it eliminates the need for multiple transmitters, significantly enhancing process cost-efficiency.
Equipped with the all-welded, resilient SuperModule sensor, this transmitter offers unmatched stability in the most demanding applications. Its Ultra for Flow performance provides a ±0.04% of reading accuracy, standardizing your measurement points and ensuring an integrated, trouble-free solution for complex industrial networks.
This industrial instrumentation supports long-range wireless communication up to 1km. The 316L SST and Alloy C-276 wetted materials ensure durability for corrosive process media. Users benefit from scaled variable output and basic diagnostics for proactive monitoring. The leak-tested assembly is ready for fast installation right out-of-the-box. With a 200:1 rangedown and SmartPower module, it provides a 10-year maintenance-free interval, making it the ideal multivariable solution for high-pressure gas and steam flow.

Choosing the correct multivariable transmitter is the first step toward long-term measurement stability. If your project requires multiple process variables (DP and Static Pressure) but lacks local power infrastructure, the Rosemount 3051S Wireless is the superior choice. Its ability to standardize on a single model number simplifies inventory management. For larger pipe sizes or high-loss systems, our [Rosemount 2051CFA Annubar Flow Meter] can be integrated as a primary element option. For material selection, while 316L SST is standard, we recommend Alloy C-276 or Tantalum for projects involving highly aggressive or sour process fluids to ensure long-term integrity.
The 3051S Wireless is engineered for "plug-and-play" efficiency, enabling quick instrumentation of measurement points without the cost of wiring. Every flowmeter comes fully configured and leak-tested from the factory, reducing potential failure points and accelerating your commissioning timeline. During installation, leverage the extended range (800 m) or high-gain antenna options to ensure a robust signal path back to your gateway. The all-welded SuperModule™ design eliminates unnecessary pipe penetrations, providing a resilient, integrated solution that withstands harsh environmental vibrations and thermal cycling.
Designed to minimize "Total Cost of Ownership," the 3051S provides up to 10 years of maintenance-free operation. The SmartPower™ module is field-replaceable, allowing technicians to refresh the power source without removing the transmitter from the process line or breaking the pressure seal. To ensure ongoing accuracy, we recommend utilizing the basic diagnostics suite to monitor signal strength and update rates (selectable from 1 sec. to 60 min.). This proactive approach ensures your WirelessHART® network maintains its >99% data reliability, even as your industrial environment evolves.
