Thiết bị đo Rosemount™ 3051SFP Integral Orifice Flow Meter static pressure, process temperature, scaled variable, mass flow
Rosemount™ 3051SFP Integral Orifice Flow Meter static pressure, process temperature, scaled variable, mass flow
The Rosemount 3051SFP Integral Orifice Flow Meter is a no-equal multivariable device customized with an integral orifice primary element. This meter run assembly provides easy installation and is engineered to facilitate highly accurate flow measurement in small line sizes (0.5 – 1.5 in. or 15 – 40 mm). This device is also engineered with built-in flow calculations for fully compensated mass flow measurements.

CHALLENGE
In order to measure large flow ranges and adapt to changing process conditions, it is often necessary to stack multiple transmitters or trade out orifice plates. This leads to increased costs, inventory, and process downtime.
OUR SOLUTION
RosemountTM Ultra for Flow (UFF) technology improves transmitter performance in high turndown applications. A single Rosemount UFF unit is able to capture the entire range, eliminating the need to stack transmitters or change out primary elements. Rosemount UFF also reduces inventory by allowing users to standardize on a single transmitter for any application. Rosemount Ultra for Flow is a transmitter accuracy class, based on a percentage of DP reading, where accuracy increases as flow rate turns down. In contrast, percent of span transmitters experience large errors when flow rate turns down.
Key Innovations
• .04% of reading specification over a 14:1 turndown
• Includes a 15 year warranty and 15 year stability
• Ultra for Flow accuracy class is exclusive to EmersonTM
