Original Rosemountee 4088A1 Pressure Transmitter 5 Valves Manifold Five-valve Group MultiVariable Magnetic Flow Meter

What is the Rosemount 4088 MultiVariable Transmitter?

The Rosemount 4088 is a smart, industrial-grade transmitter developed by Emerson (Rosemount brand) for demanding flow and pressure measurement applications. It is a multi-variable transmitter, meaning it can measure differential pressure, static (or absolute/gauge) pressure, and process temperature simultaneously.

Because of its versatility, the 4088 is especially used in oil & gas, wellhead, custody transfer, plunger lift, and other process instrumentation settings.

Key Features & Capabilities

Here are some of its standout features and technical capabilities:

Typical Applications & Advantages

• Oil & Gas / Wellheads / Plunger Lift: Because wells often have fluctuating flows, capturing spikes and low flow accurately is critical. The extended range / Enhanced for Flow option helps in these variable conditions.
• Custody Transfer / Accounting: Accurate measurement is necessary for revenue and regulatory reasons; the 4088’s multivariable approach and stable signal help ensure reliable data.
• Retrofit / Replacement: It is designed to be relatively easy to integrate into existing infrastructures, including compatibility with legacy systems.
• Harsh Environments / Remote Locations: The design’s low maintenance, durable materials, and efficient power usage make it suitable for challenging conditions.

Considerations & Limitations

• Though versatile, you must choose the correct configuration (range, materials, options) to match your process conditions (pressure ranges, temperature, compatibility) — otherwise you risk measurement errors or damage.
• In extreme applications (e.g. nuclear, ultra high temperature, etc.), one must confirm the specific variant is rated or qualified for that environment.
• The local LCD is useful, but in many installations, access may be limited; remote diagnostic tools and configuration are important.
• The “Enhanced for Flow” version is beneficial for wide turndown, but may cost more and must be selected at ordering time.
