Summary
Mass flow meter manufacturers of A mass flow meter is an instrument that accurately measures gas flow. Its measurement values are not affected by fluctuations in temperature or pressure, and no temperature and pressure compensation is required. The mass flow meter can directly measure the mass flow rate of the medium passing through the flow meter, and can also measure the density of the medium, indirectly measuring the temperature of the medium. Since the transmitter is an intelligent instrument with a single-chip microcomputer as its core, it can derive more than a dozen parameters for users based on the above three basic quantities. The mass flow meter is a new generation of flow meter with flexible configuration, powerful functions, and high cost performance. There is much more to know about mass flow meters. Here, Mass flow meter manufacturers the principle and advantages of mass flow meters will be introduced.
Mass flow meter manufacturers of Mass flow meter principle:
Mass flow meter manufacturers of The principle of the mass flow meter is Newton's second law F=Ma, when fluid flows in the vibrating tube, a Coriolis force proportional to the mass flow rate will be generated. When no fluid flows through, the vibrating tube does not produce any distortion, and the signals detected by the electromagnetic signal detectors on both sides of the vibrating tube are in phase; when fluid passes through, the vibrating tube produces distortion under the action of torque, and there will be a phase difference between the two detectors. The transmitter measures the lag time between the left and right detection signals, and this time difference multiplied by the flow calibration coefficient can determine the mass flow rate. Mass flow meter manufacturers of The density measurement principle of the mass flow meter is that the vibration frequency is inversely proportional to the square root of the fluid density. The fluid density is determined by measuring the vibration frequency. Therefore, both the measurement of fluid mass flow rate and the measurement of fluid density can be realized.
Mass flow meter manufacturers of Advantages of mass flow meters
1. Directly measure the mass flow rate of the fluid, and the current signal converted by its transmitter does not need to be specified;
2. Long service life and low maintenance rate: The measuring body of the mass flow meter is a U-shaped tube, and the two open ends of the U-shaped tube are fixed. The fluid flows in and out through it. There are no obstacles and moving parts in the tube, few failure factors, and convenient installation and maintenance.
3. Multifunctional: Mass flow meter manufacturers products can measure multiple field variables, such as flow rate, density, and temperature. At the same time. The transmitter has two independently configurable output signals, which can be used to display the measured values of flow rate, density, and temperature. One mass flow meter can replace several measuring instruments;
4. Adjustable damping time;
5. It has a powerful loop self-diagnosis function, which is convenient for fault finding.
Currently, in China's imported instruments, Mass flow meter manufacturers of mass flow meters account for a considerable proportion. Specifically, the installation number of small-diameter gas mass flow meters is relatively large, generally used in petrochemical and chemical experimental devices.
