Specification
Asmik Coriolis effect mass flow meters provide highly accurate flow measurement for liquids and gases across industries like oil, gas, chemicals, and food production. Based on the advanced Coriolis effect and technology, Asmik Coriolis meters directly measure mass flow, density, and temperature with precision up to ±0.1%.
Asmik flow meter operates on the Coriolis principle that states the circulating air has a deflection to the right in the northern hemisphere and forward to the left in the southern hemisphere as the Earth rotates on its axis.
Based on this theory, the Coriolis effect mass flow sensor works in this way: if a pipe is rotated around a point (P) while the fluid is flowing through it (toward or away from the center of rotation), that fluid will generate an inertial force, as shown in Fig.1:
The particle of mass δm moves to the right in the tube at a constant speed υ, while the tube rotates around a fixed point P at an angular velocity ω. At this time, the particle will have two acceleration components:
(1) Normal acceleration αr (Centric acceleration): its value is equal to ω2r, which is directed towards point P.
(2) Tangential acceleration αt (Coriolis acceleration): whose value is equal to 2ωυ, and the direction is αr perpendicular. The force produced by the tangential acceleration is called the Coriolis force, and its value is equal to Fc=2ωυδm.
In the Fig.1 table, the fluid Δm=ρA×ΔX,
So, the Coefficient of friction can be expressed as:
ΔFc=2ωυ×δm=2ω×υ×ρ×A×ΔX=2ω×δqm×ΔX
where A is the cross-sectional area of the tube:
Δqm=δdm/dt=υρA
For a specific rotating tube, its frequency characteristics are certain; ΔFc depends only on δqm. Therefore, the mass flow can be measured directly or indirectly by measuring the Coriolis force.

SUP Coriolis mass flow meters are widely used across various industries, including oil, gas, chemical processing, food and beverage, pharmaceutical, water treatment, environmental protection, and renewable energy applications such as hydrogen and biodiesel production.
1. What is the FCC-300 Coriolis mass flow meter?
The FCC-300 is a Coriolis mass flow meter that directly measures the mass flow rate, density and temperature of fluids in closed pipelines. It is used for liquids and gases in industries such as oil and gas, chemical, food and beverage, pharmaceuticals and water treatment.
2. How does the FCC-300 work?
The FCC-300 works on the Coriolis principle. When fluid flows through a vibrating measuring tube, each fluid particle experiences a Coriolis force (Fc = 2ωυδm) that is proportional to the mass flow. This force causes a small deformation of the tube, which the sensor detects. For a given tube, the Coriolis force depends only on the mass flow rate, so mass flow can be measured directly.
For a detailed explanation, see the FCC-300 user manual (PDF).
3. What parameters does the FCC-300 measure?
It measures mass flow, density and temperature.
4. What media can the FCC-300 measure?
The FCC-300 measures liquids and gases, and is well suited to high-viscosity fluids, slurries and suspensions. Typical media include crude oil, fuels, chemicals, food liquids, and fluids used in hydrogen and biodiesel production.
5. Does the FCC-300 need temperature or pressure compensation?
No. The FCC-300 measures mass directly, so no temperature or pressure compensation is required.
6. What is the difference between a Coriolis flow meter and an ultrasonic flow meter?
An ultrasonic flow meter uses sound waves to measure flow velocity and calculates volume flow; clamp-on versions can be installed without cutting the pipe. A Coriolis flow meter such as the FCC-300 measures mass flow directly from the vibration of its measuring tubes, and also measures density and temperature, without temperature or pressure compensation.
7. What is the difference between a thermal mass flow meter and a Coriolis mass flow meter?
A thermal mass flow meter measures mass flow based on heat transfer and is designed for gases, often in large pipes with insertion installation. A Coriolis mass flow meter measures mass flow through tube vibration and can be used for liquids, gases, slurries and suspensions, with higher accuracy and simultaneous density measurement. See our MIK-MF thermal mass flowmeter for gas applications.
