Product Details
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:
Feature | Details |
Accuracy | Mass flow measurement error of ± 0.05 % with the PremiumCal calibration option. |
Nominal Diameter | DN 8 to DN 250 (≈ ⅜ to 10 inches) |
Temperature range (medium) | From −196 °C up to +350 °C (i.e. very low cryogenic temps up to high, harsh conditions) |
Process connections / installation | Space-saving design. The Promass F 300 requires minimal
inlet/outlet run (i.e. shorter straight runs upstream/downstream)
due to its design. |
Multiple measurands | Measures more than just mass flow — also density, temperature.
Optionally volume flow (and corrected volume), depending on setup. |
Connectivity, display, I/O | Has a compact dual-compartment housing; up to three I/Os
(input/output). Local backlit display, touch control; remote
display possible. Some versions allow WLAN access. |
Diagnostics & Verification | Incorporates Heartbeat Technology for continuous diagnostics and verification, which helps with
process safety and can extend calibration intervals. |
Robustness | Designed to be immune to fluctuating / harsh environments: large
temperature swings, pressure, etc. Many approvals and certificates
(hygienic, NACE, PED, etc.) depending on configuration. |
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.
