Rosemount 3051CD 3051TG Emerson Compact Pressure Transmitter Tank Level Line Pressure Measurement Price

The blue DP cell that’s been on every orifice plate run since the 90s

Orifice plates are cheap and simple, and the 3051 differential transmitter is the one that always works with them. It reads the tiny pressure drop across the plate, calculates flow in the DCS, and just sits there for 15–20 years. New ones have better turndown and diagnostics, but the mounting is the same as the old 1151 so you can swap them during turnaround without changing manifolds.

• High static pressure versions – up to 6000 psi line pressure
• Low DP ranges – down to inches of water
• Built-in square root for direct flow output
• Remote seals for dirty service
• Local indicator – see the DP right on the transmitter

• Steam flow measurement
• Natural gas custody transfer
• Process liquid flow
• Air flow in ducts

Q: Does it replace my old 1151 DP cell?
A: Yes – same 3-valve manifold bolts right up.

Q: Can I use it with remote seals?
A: Yes – capillary systems for hot or dirty fluids.
