Applications of the 3051C Coplanar Pressure Transmitter

• Flow Measurement
• Paired with primary elements (orifice plates, venturi tubes, pitot tubes, wedge meters) to calculate flow using differential pressure.
• Widely used in oil & gas pipelines, chemical dosing, and steam distribution.
• Level Measurement
• Applied in pressurized or vented tanks to measure liquid level by detecting hydrostatic pressure difference.
• Common in storage tanks, separators, and distillation columns.
• Filter & Pump Monitoring
• Detects pressure drop across filters, strainers, and membranes to indicate clogging or fouling.
• Monitors pump suction/discharge differential to ensure efficiency and prevent cavitation.
• Process Pressure Monitoring
• Measures low‑range differential, gauge, or absolute pressures (–25 to 25 inH₂O with 0.5 inH₂O span).
• Ensures safe operation in sensitive processes like pharmaceutical production or ultrapure water systems.
• Energy & Utility Systems
• Steam flow and condensate return monitoring in power plants.
• Compressed air and gas distribution networks in industrial facilities.
• Water & Wastewater Treatment
• Clarifier level monitoring, membrane filtration control, and sludge blanket detection.
• Ensures compliance with environmental discharge standards.

FAQ – Rosemount™ 3051C Coplanar Pressure Transmitter

Q1: What is the Rosemount 3051C Coplanar Pressure Transmitter used for?

A1: It is designed for differential, gauge, and absolute pressure measurements. Typical applications include flow measurement (with primary elements), liquid level monitoring in tanks, filter/pump monitoring, and general process pressure control.

Q2: What is the measurement range of the 3051C?

A2: The transmitter supports a wide range of spans. A common configuration is –25 to 25 inH₂O with a minimum span of 0.5 inH₂O, making it highly sensitive for low‑pressure applications.

Q3: What output signals are available?

A3: The standard output is 4–20 mA with HART® protocol, enabling both analog signal transmission and digital communication for configuration and diagnostics.

Q4: What industries typically use the 3051C?

A4: It is widely applied in oil & gas, chemical processing, power generation, water and wastewater treatment, and general industrial automation.

Q5: What is the advantage of the coplanar design?

A5: The coplanar platform allows direct integration with manifolds and primary flow elements, reducing installation complexity, improving accuracy, and simplifying maintenance.

Q6: How accurate is the 3051C?

A6: The reference accuracy is typically ±0.04% of span, with excellent long‑term stability and up to 100:1 turndown capability.

Q7: What certifications are available?

A7: The 3051C is available with global certifications such as CE, ATEX, IECEx, and others for use in hazardous or explosive environments.

Q8: Can the 3051C be remotely configured?

A8: Yes. Using HART® communication, the transmitter can be configured, calibrated, and diagnosed remotely with compatible handheld communicators or asset management software.

Q9: What are the common options (K5, E5, I5, DF, etc.) in the model codes?

A9: These suffixes indicate special options such as materials, process connections, or certifications. For example:

• K5: Stainless steel housing option
• E5: Special electrical connection or grounding option
• I5: Isolated electronics or insulation option
• DF: Special diaphragm or process-wetted material option

Q10: How does the 3051C compare to other Rosemount 3051 models?

A10: The 3051C is the versatile, cost‑effective coplanar model. The 3051S offers higher accuracy and advanced diagnostics, while the 3051T is a simpler in‑line transmitter for gauge/absolute pressure.
