Coriolis force mass flowmeter
Coriolis force is a force proportional to the vector product of the linear velocity of the linear motion and the angular velocity of the rotational motion when an object is in both linear motion and rotational motion. The Coriolis mass flowmeter uses this principle. Using the magnet and coil assembly installed on the measuring tube, under the action of alternating current, the two parallel measuring tubes vibrate at their natural frequency. When fluid flows through the measuring tube, the Coriolis force causes the vibration of the measuring tube to shift in phase. The greater the mass flow rate of the fluid, the greater the vibration phase shift of the measuring tube. By detecting the vibration phase shift of the two measuring tubes, the mass flow value can be obtained.
Main Features
1. Unchallengeable performance on liquid mass flow, volume flow, and density measurement
2. Unique design delivers unparalleled measurement sensitivity and stability
3. Guarantees consistent, reliable performance over the widest flow range
4. Designed to minimize process, mounting, and environmental effect
Application
The 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
Pharmaceutical
Painting
Paper making
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.
Low temperature fluid, like liquid oxygen and liquid nitrogen, the low temperature up to -200℃
High temperature fluid, the maximum temperature up to 300℃
High pressure fluid, like slurry flow measurement for oil drilling cementing
Working Principle
If a pipe is rotated around a point (P) while liquid is flowing through it (toward or away from the center of rotation), that fluid will generate an inertial force, with reference to Figure 1.1:
Sensor Structure
Mass flow meter sensor consists of measurement tube, driving device, position detector, support structure, the temperature sensor, housing, etc.
① Supporting structure: the measuring tube fixed on the supporting structure as the vibrating axis.
② The measuring tube (Vibrating tube): consist of two parallel tubes.
③ Position detector: used for the measurement of measuring tube distortion.
④ Drive device: generate electromagnetic force to drive measuring tube to make it vibrate close to resonance frequency.
⑤ Housing: Protect the measuring tube, driving unit and detector.
