Coriolis Mass Flowmeter
Coriolis flowmeters are the leading precision flow and density measurement solution, which offer the most accurate and repeatable mass measurement for liquids, or slurries. It called universal meters, Our meters offer the most accurate measurement available for virtually any process fluid, while exhibiting exceptionally low pressure drop.
It has the following distinguishing advantages:
- Simultaneous measuring of mass flow, density, temperature and viscosity
- Unchallengeable performance on liquid mass flow, volume flow, and density measurement
- Unique design delivers unparalleled measurement sensitivity and stability
- Guarantees consistent, reliable performance over the widest flow range
- Designed to minimize process, mounting, and environmental effect
- Measuring principle independent of the physical fluid properties and the flow profile
- No inlet/outlet runs necessary
- They are particularly helpful for handling liquids whose viscosity changes according to velocity while temperature and pressure remains constant.
Working Principle
Each Coriolis flowmeter has one or more measuring tubes which an exciter causes to oscillate artificially. As soon as the fluid starts to flow in the measuring tube, additional twisting is imposed on this oscillation due to the fluid‘s inertia. Two sensors detect this change of the tube oscillation in time and space as the “phase difference.” This difference is a direct measure of the mass flow.
In addition, the fluid density can also be determined from the oscillation frequency of the measuring tubes. The temperature of the measuring tube is also registered to compensate thermal influences. The process temperature derived from this is available as an additional output signal.
Application Range
The MTAFTCMF mass flow meter can be used in the following fields to meet the requirements of ingredient, mixing processes and commercial measurement
- Chemical: containing chemical reaction system
- Petroleum: moisture content analysis
- Lipids: including vegetable oils, animal fats and other oils
- Textile printing and dyeing
- Fuel: crude oil, heavy oil, coal slurry, lubricant and other fuels
- Food: gas dissolving beverage, health drink and other liquid
- Transportation: pipeline liquid measurement
- High pressure fluid, like slurry flow measurement for oil drilling cementing
