The Rosemount 3051S Wireless Differential Pressure Flow Transmitter is a best-in-class measurement solution that integrates scalable technology with the industry-proven security of a WirelessHART® network. As a premier wireless DP flow transmitter, it eliminates the high cost of wiring while delivering greater than 99% data reliability. This device is designed for seamless integration with a wide variety of primary flow elements that can be pre-assembled to the transmitter for an optimized, ready-to-install solution.
Built on the all-welded hermetic SST SuperModule™ platform, this transmitter is engineered for durability, offering an industry-leading 15-year limited warranty and 15-year stability. The Ultra and Ultra for Flow performance classes enable high-precision measurements with up to 0.025% of span accuracy. Additionally, a 200:1 rangedown provides the application flexibility needed to produce reliable measurements across varying flow conditions.
The Rosemount 3051S features the SmartPower™ module, which provides up to 10 years of maintenance-free operation and allows for field replacement without removing the transmitter from the process. To ensure maximum process visibility, the device includes advanced diagnostics such as Process Intelligence, Loop Integrity, and Plugged Impulse Line detection. These insights help operators identify issues before they impact performance.
To simplify site commissioning, complete flow assemblies arrive leak-tested and calibrated, a process that can reduce potential leak points by up to 70%. The straightforward wireless installation enables the quick instrumentation of measurement points in remote or hazardous locations where traditional wired solutions are not cost-effective.
