Frequently Asked Questions

1. What types of mass flowmeters does Asmik offer?

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.

2. How does a Coriolis mass flowmeter work?

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.

3. How does a thermal mass flowmeter work?

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.

4. Coriolis or thermal: which mass flowmeter should I choose?

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.

5. What parameters can a Coriolis mass flowmeter measure?

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.

6. Why measure mass flow instead of volume flow?

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.

7. What media can the Coriolis flowmeters measure?

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.

8. What gases can the MIK-MF thermal mass flowmeter measure?

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.

9. What pipe sizes are available?

FCC800

U-shaped type: DN3–DN150
Micro-bend type: DN8–DN100
Straight pipe type: DN8–DN50
Inverted triangle type: DN1–DN2

FCC-300

U-type: DN20–DN150
Triangular type: DN3–DN15
Straight tube type: DN8–DN80

10. How accurate are Asmik mass flowmeters?

FCC800: flow accuracy class 0.15, 0.2 or 0.5; density ±0.001 g/cm³ (±1 kg/m³); temperature ±1 °C or ±0.5% of reading, whichever is greater; repeatability is 1/2 of the accuracy.
FCC-300: flow accuracy 0.1%, 0.15% or 0.2%; density accuracy 0.002 g/cm³; density range 0.3–3.000 g/cm³; repeatability is 1/2 of the measurement error.
MIK-MF: ±2.5%.

11. What is the turndown ratio or flow range?

FCC800: 10:1 for U-shaped, micro-bend and inverted triangle types; 5:1 for the straight pipe type.
MIK-MF: flow velocity 0.1–100 Nm/s.

The actual flow range depends on the meter size. Please share your minimum and maximum flow for sizing.

12. What medium temperatures can the meters handle?

FCC800: temperature measurement range -240 °C to 350 °C.
FCC-300: standard type -50 °C to 200 °C or -20 °C to 200 °C; high-temperature type -50 °C to 350 °C; low-temperature type -200 °C to 200 °C.
MIK-MF: sensor -40 °C to 300 °C; converter -20 °C to 45 °C.

13. What pressure ratings are available?

17. Does a Coriolis flowmeter need straight pipe runs?

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.

18. How much maintenance do mass flowmeters need?

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.

19. Can the Coriolis flowmeter be used for custody transfer?

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.

20. Which industries use Asmik mass flowmeters?

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.
