Emerson Rosemount 2051CFC Coplanar Flow Configuration is a differential pressure transmitter solution developed on Emerson’s patented Coplanar™ platform. Thanks to the coplanar body design, the transmitter and manifold are integrated into a single structure, creating a more compact, more reliable, and easier-to-install flow measurement system.
When used with orifice plates, venturi tubes, averaging pitot tubes, and other primary flow elements, it provides highly accurate differential pressure measurement.
Key advantages:
✔ Compact Coplanar design
✔ Fewer connection points
✔ Lower leakage risk
✔ Easy installation and maintenance
✔ Long-term measurement stability
✔ Reduced installation cost in OEM and EPC projects
Rosemount 2051CFC is a Coplanar Flow Configuration model developed for differential pressure-based flow measurement.
Unlike standard differential pressure transmitters, the following are optimized on a single body:
transmitter
manifold
impulse connections
This design:
reduces installation time
increases process reliability
lowers maintenance costs
optimizes total cost of ownership (TCO)

Model codes must always be verified against Emerson technical documentation and process requirements.
Rosemount 2051CFC operates as follows:
Differential pressure is generated across the primary flow element.
The coplanar sensor detects this pressure difference.
The sensor signal is processed by the electronic module.
The microprocessor applies temperature compensation.
The measurement is transmitted via 4–20 mA or digital communication protocols to PLC/DCS systems.
Flow values are calculated in real time and used in process control.
