Differential pressure transmitters are critical in industrial processes for flow measurement, hydrostatic level calculations, and filter monitoring. The Emerson Rosemount 2051CD model, with its compact design and economic price advantage, provides a strong solution for OEM applications and cost-focused projects.
Compared to the Rosemount 3051CD, the 2051CD has a smaller body size while still meeting essential process requirements and optimizing investment costs. This makes the Rosemount 2051CD an ideal alternative for users seeking a balance of price and performance.
Rosemount 2051CD codes define transmitter configuration:
CD (Compact Differential Pressure): For flow measurement, level measurement, and filter monitoring
Measurement range: Indicates differential pressure capacity
Process connection: Flange or NPT options
Output: 4–20 mA HART or digital protocol
Housing: Aluminum or stainless steel
Correct code selection prevents technical mismatches during procurement.

These codes must be verified against the Rosemount 2051 datasheet and selected according to process conditions.
2051CD transmitters operate as follows:
Differential pressure detection – Measured via diaphragm between two points
Flow or level calculation – Differential pressure converted to flow rate or liquid level
Signal conversion – Measurement converted to 4–20 mA HART or digital protocol
System integration – Signal transmitted to DCS/PLC systems for process control
Typical applications:
Flow measurement (orifice, venturi, pitot tube)
Hydrostatic level measurement
Filter and membrane monitoring
Energy and process optimization
Power plants: Steam line flow measurement
Petrochemical and refinery: Gas and liquid flow control
Water and wastewater: Tank level and pipeline flow measurement
OEM applications: Skid packages and compact process systems
