Frequently Asked Questions
Q1: What is the Rosemount 3051 Pressure Transmitter used for?
It measures process pressure and can support level and flow measurement when paired with the appropriate configuration or primary measuring element.
Q2: What is the accuracy of the Rosemount 3051?
Reference accuracy is up to 0.04% on applicable configurations. Actual performance depends on the selected model, range and operating conditions.
Q3: Can the Rosemount 3051 measure tank level?
Yes. A suitable pressure transmitter configuration can measure hydrostatic pressure to determine liquid level in vented or pressurized tanks.
Q4: Does the Rosemount 3051 support wireless communication?
WirelessHART® is available as a selectable option. Bluetooth® connectivity is also available on supported versions for local configuration and maintenance.
Q5: What is the difference between Coplanar and In-Line versions?
The Coplanar design supports differential pressure measurement and flexible assembly with compatible flanges, manifolds and seals. The In-Line design is optimized for direct installation on a process pipe or vessel.
Q6: What information should I provide when ordering?
Confirm the measurement type, pressure range, process connection, wetted materials, output protocol, display requirements and applicable certifications. The exact model code should be checked against the manufacturer's documentation.
