FCC-300 Coriolis Mass Flowmeter

Asmik offers two measuring technologies:

• Coriolis mass flowmeters: FCC800 and FCC-300, for liquids, gases, slurries and suspensions.
• Thermal mass flowmeter: MIK-MF insertion type, for gas measurement.

The flow tubes are driven to vibrate at their natural frequency. As the medium flows through the vibrating tubes, the Coriolis force causes a phase shift (twist) between the inlet and outlet sides of the tubes. This phase shift is proportional to the mass flow rate. The vibration frequency changes with the fluid's density, so density is measured at the same time. The transmitter converts these signals into mass flow, density and temperature values.

The MIK-MF is based on the principle of thermal diffusion and uses the constant temperature difference method. The heat carried away by the flowing gas is related to its mass flow rate, so the meter measures gas mass flow directly without separate temperature and pressure compensation.

• Coriolis (FCC800 / FCC-300): measures liquids, gases, slurries and suspensions; high accuracy (down to 0.1%); also measures density and temperature; pipe sizes from DN1 to DN150.
• Thermal (MIK-MF): for steady-state gases only; insertion installation; suitable for large pipes from DN65 to DN1000; accuracy ±2.5%; commonly used for gas consumption monitoring and leakage analysis.

If you are unsure, send us your medium and operating conditions and our engineers will recommend a suitable type.

The FCC800 and FCC-300 directly measure mass flow rate, density and temperature. Volume flow is calculated from mass flow and measured density, so one device can replace separate flow, density and temperature instruments.

Volume changes with temperature and pressure, while mass does not. A mass flowmeter gives a direct mass reading without temperature or pressure compensation, which is useful for batching, dosing, material balance, storage and transfer applications.

They can measure gases, liquids, slurries and suspensions. Measurement does not depend on conductivity, so non-conductive fluids and viscous oils can also be measured. Typical media include crude oil, fuel oil, chemicals, solvents, food liquids and polymer solutions.

The MIK-MF is designed for steady-state gases. It is not suitable for unstable media such as acetylene and boron trichloride. Please send us the gas composition for confirmation before ordering.

• MIK-MF: IP65; stainless steel body.

The FCC800 requires no upstream or downstream straight pipe runs and no flow conditioning, so it can be installed in compact piping layouts. Insertion-type thermal flowmeters such as the MIK-MF generally need straight pipe sections to ensure a stable flow profile. Please refer to the installation manual or contact our engineers for site-specific requirements.

Coriolis flowmeters have no moving parts and no internal obstructions, so wear and clogging are minimal. Zero-point monitoring helps maintain stability. The MIK-MF thermal flowmeter is vibration resistant and designed for easy installation and maintenance.

The FCC800's high accuracy makes it suitable for fiscal and custody transfer applications, and the FCC-300 follows the GB/T 31130-2014 standard for mass flow measurement. Custody transfer use usually requires metrological approval under local regulations. Please contact us to confirm the certificates available for your project.

Typical applications include oil and gas, chemical processing, pharmaceuticals, food and beverage, marine fuel management, water and wastewater treatment (such as sludge and polymer dosing), paper manufacturing, and renewable energy such as hydrogen and biodiesel production.
