Flow measurement is one of the components of measurement science and technology, which is closely related to the national economy, national defense construction, and scientific research. Doing this job well plays an important role in ensuring product quality, improving production efficiency, and promoting the development of science and technology.
Flow rate is a relatively complex measurement parameter in the measurement of thermal parameters. There are many factors that affect measurement, and choosing a suitable flow measurement method often requires comprehensive comparison from multiple aspects. Among the many factors that affect flow measurement, the most important one is the fluid characteristics, especially in the petrochemical industry where the fluid characteristics are very complex, making it difficult to choose flow methods. The measurement methods are generally selected as follows:
Fluid containing solid particles - wedge flowmeter, electromagnetic flowmeter, Coriolis flowmeter;
Two phase fluid - Coriolis flowmeter, electromagnetic flowmeter, rotor flowmeter;
Slurry fluid - wedge flowmeter, Doppler ultrasonic flowmeter;
Corrosive fluids - electromagnetic flowmeter, metal tube rotor flowmeter, Coriolis flowmeter;
High viscosity fluids - conical inlet orifice flowmeter, electromagnetic flowmeter, elliptical gear flowmeter, Coriolis flowmeter;
Non Newtonian fluids - electromagnetic flowmeter, Coriolis flowmeter;
High flow fluids - flute shaped averaging tube flowmeter, Velbar flowmeter, insertion flowmeter;
Micro flow fluid - elliptical gear flowmeter, electromagnetic flowmeter, metal tube float flowmeter;
Low temperature fluid - turbine flowmeter;
Natural gas, liquefied petroleum gas - gas ultrasonic flowmeter;
Low pressure loss fluid - Doyle tube flowmeter, Venturi flowmeter, bend tube flowmeter.
The above are various types of flow meters suitable for various media. Choosing a suitable flow meter can play a great role in industrial production and bring convenience to production.
