Coriolis Flowmeter Proline Promass F 300 Series 8F3B08 8F3B15 8F3B1F 8F3B1H 8F3B25 8F3B40 8F3B50 8F3B80

What is it

The Promass F 300 is a series of Coriolis mass flowmeters designed for high-accuracy measurement of liquids and gases in industrial processes. It is part of the Proline Promass F line from Endress+Hauser.

The device combines:

• A sensor using the Coriolis principle (measuring mass flow directly)
• A transmitter / electronics unit that handles signal processing, diagnostics, and output.

How it works (Coriolis principle)

The Coriolis flowmeter operates by vibrating flow tubes; as fluid flows through them, the Coriolis force causes tiny twists or phase shifts in the tubes. These distortions are measured and converted into mass flow. Because the measurement depends on inertial effects, it is largely independent of fluid properties like viscosity or density (though density and temperature are also measured for compensation/correction).

Because it's a mass flow measurement, it's inherently more accurate for many control, billing, and safety-critical applications compared to volume-only meters, especially when fluid conditions vary.

Key Features & Specifications

Here are the main features and some of the important technical parameters:

Pros & Considerations

Advantages:

• Very high accuracy even under varying process conditions.
• Multivariable measurement reduces need for separate sensors for density, temperature, etc.
• Robust design suitable for demanding industrial applications.
• Diagnostics and verification built in (Heartbeat) helps ensure reliability.

Things to check / watch out for:

• Cost: Premium accuracy, plus options (remote display, additional I/O, housing material, etc.), will increase price.
• Maintenance / calibration: Even though diagnostics help, you’ll want to verify calibration over time.
• Fluid suitability: While many options exist, you must ensure the wetted materials are compatible with the fluid (chemical compatibility, temperature, pressure).
• Installation: Although inlet/outlet run requirements are reduced, the meter must still be installed properly to avoid distortion, vibrations, or gas entrainment, etc.

Typical Applications

Some typical use-cases for the Promass F 300 include:

• Custody transfer of liquids/gases where billing depends on accurate mass flow measurement.
• Process control loops in chemical, petrochemical, and pharmaceutical industries.
• Batching and dosing applications, where accurate measurement of mass or concentration is needed.
• Applications with varying fluid properties, e.g. changes in density, temperature, composition.
• Environments requiring hygienic / sanitary approvals (food & beverage, biotech) if configured accordingly.
