What are the advantages and disadvantages of Coriolis flowmeter?

Advantages:
? ??
1. Coriolis mass flowmeter measures mass flow immediately and has high measurement accuracy.
? ??
2. The field of measurable fluid mechanics is universal, including various liquids with low viscosity liquid, slurry with solid matter, liquid with a small amount of vapor, and medium and high pressure vapor with sufficient relative density.
? ??
3. The vibration amplitude of the measuring pipe is small, which can be regarded as a non subject moving part, and there is no obstruction or theme moving part in the measuring pipe.
? ??
4. The matching pairs are not sensitive to the distribution of upstream flow, so there is no provision for upstream, middle and downstream connecting sections.
? ??
5. The measured value is not sensitive to the viscosity of fluid mechanics, and the change of fluid density has little harm to the value of measurement.
? ??
6. Many main parameters can be measured, such as the relative density measured in the current period, and thus the concentration value contained in the measurement of the amount and concentration of substances in the aqueous solution can be obtained.
? ??
Disadvantages:
? ??
1. The zero drift of Coriolis mass flowmeter caused by zero point instability is harmful to the further improvement of its accuracy, so many types of instrument panels can only choose to divide the total deviation into two parts: base deviation and zero instability measurement.
? ??
2. Coriolis mass flowmeter can not be used to measure low density substance and bottom pressure vapor; the gas content in liquid exceeding a certain limit (depending on the model) will significantly harm the measured value.
? ??
3. Coriolis mass flowmeter is more sensitive to external vibration. In order to avoid pipeline vibration hazard, the air flow meter of most types of Coriolis mass flowmeter has higher requirements for fixed installation.
? ??
4. It can not be used for very large pipe diameter, which is limited to 150 (200) mm at present.
? ??
5. The inner cavity of the measuring tube is damaged, eroded or accumulated scale, which will harm the measurement accuracy, especially for the Coriolis mass flowmeter of thick wall tube.
? ??
6. The working pressure is damaged greatly, which is different from the capacity type instrument panel. Some models of Coriolis mass flowmeter are even 100% larger than the capacity type instrument panel.
? ??
7. Most models of Coriolis mass flowmeter have large net weight and volume.
? ??
8. The price is quite expensive. The price of a set of overseas pressure transmitter is 5000-10000 US dollars, which is about 2-5 times of that of the same caliber pressure transmitter; the price of Chinese pressure transmitter is about 2-8 times of that of pressure transmitter.
