Measuring Principle
Coriolis mass flowmeter consists of two parts: a sensor and a transmitter, according to the principle of Coriolis, let the meter tube vibrate when there is a medium passing through. Sensor detects and analyzes the change of frequency, phase difference and temperature of the meter tube. So that it can directly measure the mass flow-rate of the medium, and density is calculated by vibrate frequency. Other process variables also can be obtained, like mass flow, volume flow, density and temperature.
Product Features
· Direct measurement of the mass flow of fluid, eliminating the problem of volumetric flow measurement.
· Multi-functional.
Can simultaneously measure flow, density, temperature and other field variables, the transmitter has two separately configurable output signal, can be used to display the flow, density, temperature and other measurement values, a mass flow meter can replace multiple measuring instruments.
· High accuracy. For liquid large can reach ± 0.1 ± (stability of the zero point / actual flow) × 100%, gas can reach ± 0.25 ± (stability of the zero point / actual flow) × 100%.
· Wide range ratio, up to 100:1, the low-frequency sensor limit can reach 1000:1
· Long service life and low maintenance. No obstructions in the pipeline, no moving parts, few failure factors, easy installation and maintenance.
· Adjustable damping time.
· Strong circuit self-diagnostic function for easy fault finding.

F&V GROUP is a global industrial measurement company committed to delivering innovative, energy-efficient solutions for temperature, pressure, flow, and level applications. Established in 2021, the group unites strong international expertise with localized manufacturing and service capabilities.
Our journey began in 2011 with the founding of FVLUOKY in Wales, UK—a brand built on precision engineering and technological excellence. Over the years, FVLUOKY became a trusted name in industrial measurement across international markets.
To better serve the Asia-Pacific region, Fuyi Intelligent Instrument (Shanghai) Co., Ltd. was established in 2019, introducing FVLUOKY’s product lines to China with localized assembly, testing, and innovation. Fuyi products are fully certified (ISO, CE, TS, CPA) and tailored to regional industry needs.
With the formation of F&V GROUP in 2021, our brands were strategically integrated to accelerate global growth. By 2024, F&V had become a leading force in China and began expanding its footprint to international markets—bringing high-performance, sustainable measurement solutions to customers worldwide.
At F&V, we combine global innovation with local insight—driven by a commitment to quality, sustainability, and customer success.
