Advantages and disadvantages of turbine flowmeter

The turbine flowmeter is the main type of velocity flowmeter. It uses a multi-blade turbine to sense the average velocity of the fluid, thereby deriving the flow rate or total amount. Generally, it consists of a sensor and a display, and can also be made into an integral type. (V-cone flowmeter)

　　Turbine flowmeters Turbine flowmeters, volumetric flowmeters, and Coriolis mass flowmeters are known as the three types of flowmeters with the best repeatability and accuracy. As one of the ten major types of flowmeters, their products have developed into a multi-variety, multi-series mass production scale. (V-cone flowmeter)

　　advantage:

　　1. High precision, among all flow meters, it is the most accurate flow meter; (V cone flow meter)

　　2. Good repeatability;

　　3. Zero drift, strong anti-interference ability;

　　4. Wide range; (V-cone flowmeter)

　　5. Compact structure.

　　shortcoming:

　　1. Unable to maintain calibration characteristics for a long time; (V-cone flowmeter)

　　2. Fluid physical properties have a great influence on flow characteristics.

　　Turbine flowmeters are widely used in the following measurement objects: petroleum, organic liquids, inorganic liquids, liquefied gas, natural gas, food, beverages and cryogenic fluids. In Europe and the United States, turbine flowmeters are natural gas metering instruments second only to orifice flowmeters in terms of usage. The Netherlands alone has used more than 2,600 gas turbine flowmeters of various sizes and pressures ranging from 0.8 to 6.5 MPa on natural gas pipelines. They have become excellent natural gas metering instruments. (V-cone flowmeter)
