Endress+Hauser Promass 83F08 Coriolis Flow Meter

NOS Endress+Hauser Promass 83F Coriolis Mass Flow Meter (P/N: 83F08-ACVSA)

The Endress+Hauser Proline Promass 83F08 (Order Code: 83F08-ACVSA) is a tube Coriolis mass flow measuring system designed for continuous, multivariable monitoring of critical fluids under demanding operating environments. Marine propulsion systems, offshore platforms, bunkering skids, and continuous chemical injection processes rely on the Promass F sensor for its immune-to-vibration geometry and direct mass flow measurement.

Unlike volumetric flowmeters (such as oval gear, turbine, or differential pressure meters) that require separate temperature and pressure compensation loops, the Promass 83F simultaneously measures:

1. Direct Mass Flow (independent of fluid viscosity and density changes)
2. Fluid Density
3. Fluid Temperature (via integrated platinum RTD elements)
4. Derived Volumetric & Concentration Values (e.g., standard volume, °Brix, °API, % concentration)

Constructed with dual measuring tubes encased in a heavy-duty stainless steel secondary containment housing, the DN08 (3/8″) sensor provides accurate dosing, chemical injection, boiler fuel consumption metering, and cylinder lubrication monitoring.

Technical Details

Applications

• Marine Fuel Consumption & MDO/HFO Monitoring: Engine feed, return line mass balancing, and auxiliary boiler fuel consumption tracking compliant with IMO MARPOL Annex VI regulations.
• Cylinder Lubrication Injection Systems: Precise low-flow batching of crosshead and trunk-piston engine cylinder oils at varying operating temperatures.
• Chemical Dosing & Catalytic Reactors: High-precision metering of aggressive additives, inhibitors, emulsifiers, anti-scaling chemicals, and acid slurries.
• Offshore Chemical Injection Skids (MEG, TEG, Methanol): Continuous high-pressure offshore injection tracking demanding zero recalibration drift.
• Precision Dosing & Filling Stations: High-speed filling, batch packaging, and drum filling operations utilizing the Promass 83 onboard software batching algorithm.

Compatibility

• Distributed Control Systems (DCS) & PLCs: Fully compatible via standard 4–20 mA HART, Modbus RTU, or pulse transmission to Siemens SIMATIC S7-1200/1500, Rockwell Allen-Bradley ControlLogix, Emerson DeltaV, ABB Freelance, and Schneider Modicon.
• Marine Alarm & Monitoring Systems (AMS): Direct plug-in integration to Kongsberg K-Chief, Lyngsø Marine, Wärtsilä Nacos Platinum, and Consilium marine engine management topologies.
• Endress+Hauser Family Interoperability: Compatible with Proline Promass 80, 83, and 84 transmitter head replacements. The sensor body connects directly to legacy or upgraded Promass transmitters via matching factory calibration sensor matrices.

Frequently Asked Questions

What is the maximum flow rate capacity of the Endress+Hauser Promass 83F08?

The DN08 (3/8″) Coriolis sensor has a nominal full scale flow capacity of 2,000 kg/h (approximately 33.3 kg/min or 73.5 lb/min). The device retains stable linearity and zero-point repeatability down to 1% to 2% of this range depending on fluid viscosity.

Can the Promass 83F08 meter measure both heavy fuel oil (HFO) and marine gas oil (MDO)?

Yes. Because Coriolis meters measure mass inertia directly rather than fluid velocity or volume, changes in viscosity, specific gravity, or pressure do not corrupt measurement accuracy. The wetted tube materials (904L stainless steel / Alloy C-22) handle both cold distilled fuels and heated heavy bunker fuels up to 200 °C without recalibration.

Does this flow meter require straight pipe runs before and after installation?

No straight inlet or outlet runs are required for Coriolis meters. Unlike magnetic or vortex meters that depend on an undisturbed Reynolds flow profile, the Promass 83F can be fitted directly adjacent to bends, valves, or pipe reducers, making it suitable for tight marine engine room spaces.

What does “NOS” condition signify for this Endress+Hauser unit?

NOS stands for New Old Stock. The flow meter was manufactured and maintained as an uninstalled, unenergized industrial spare. It comes complete with its factory electronics intact, untouched flow tubes, original terminal blocks, and has never been exposed to corrosive service media.

What is the advantage of the Promass 83 transmitter compared to the Promass 80?

The Promass 83 transmitter contains enhanced software modules for advanced fluid diagnostics, integrated batching control, continuous density tracking, concentration calculations, and multi-variable I/O card allocations, whereas the Promass 80 is limited to standard mass flow and volume calculation loops.
