Turbine flowmeter is the main type of velocity flowmeter. It uses a multi-blade rotor (turbine) to sense the average flow rate of the fluid and derive the flow rate or total amount from it.
Generally, it is composed of two parts, a sensor and a display, and it can also be made into an integral type.
Turbine flow meters, positive displacement flow meters, and Coriolis mass flow meters are known as the three types of flow meters with the best repeatability and accuracy. As one of the top ten types of flow meters, their products have developed into a variety of The scale of series mass production.
(1) High precision, among all flow meters, it is the most accurate flow meter;
(2) Good repeatability;
(3) Yuan zero drift, good anti-interference ability;
(4) Wide range;
(5) Compact structure.
(1) The calibration characteristics cannot be maintained for a long time;
(2) Fluid physical properties have a greater impact on flow characteristics.
Turbine flowmeters are widely used in the following measurement objects: petroleum, organic liquids, inorganic liquids, liquefied gas, natural gas and cryogenic fluids
In Europe and the United States, turbine flowmeters are natural metering instruments second only to orifice flowmeters in terms of usage.Only in the Netherlands, more than 2,600 gas turbines of various sizes and pressures from 0.8 to 6.5 MPa are used on natural gas pipelines. They have become excellent natural gas metering instruments.
