Turbine flow meters, the main type of velocity flowmeters, use a multi-blade rotor (turbine) to sense the average flow rate of the fluid, and derive the flow or total amount of meters.
Generally, it consists of two parts, a sensor and a display, or it can be made into a unitary type.
Turbine flowmeters and volumetric flowmeters, Coriolis mass flowmeters are called three types of repeatability and precision** in flowmeters. As one of the ten types of flowmeters, their products have been developed into many varieties and more. The scale of series mass production.
(1) High precision, among all flow meters, is a *precise flow meter;
(2) good repeatability;
(3) Yuan zero drift, good anti-interference ability;
(4) The range is wide;
(5) Compact structure.
(1) The calibration characteristics cannot be maintained for a long time;
(2) Fluid properties have a large impact on flow characteristics.
Turbine flowmeters are widely used in some of the following measurement objects: petroleum, organic liquids, inorganic fluids, liquefied gases, natural gas and cryogenic fluids. In Europe and the United States, turbine flowmeters are second only to the natural metering of orifice flowmeters. Instrumentation, the Netherlands alone has used more than 2,600 gas turbine flowmeters of various sizes and pressures from 0.8 to 6.5 MPa on natural gas pipelines, which have become excellent natural gas meters.
