Turbine flow meters, the main type of velocity flow meters,which are instruments that use multi-blade rotor (turbine) to sense the average flow velocity of fluid, and derive the flow or total amount.Generally it consists of two parts, the sensor and the display, and it can also be made into a whole. Turbine flow meters, volumetric flow meters and Coriolis mass flow meters are called the three types of flow meters with the best repeatability and accuracy. As one of the ten types of flow meters, their products have developed into the scale of mass production of multiple varieties and series.
(1)High accuracy. In all flow meters, it belongs to the most accurate flow meter.
(3)No zero drift, good anti-interference ability;
(1) The calibration characteristics cannot be maintained for a long time;
(2) Fluid properties have a great impact on flow characteristics.
Turbine flow meters 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 flow meters are second only to orifice plate flow meters for natural gas meters. In the Netherlands alone, more than 2,600 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 meters.
