Turbine Flowmeter, is the main type of velocity flowmeter, it uses multiple blades of the rotor (turbine) to feel the average flow velocity, so as to derive the flow rate or total meter. In general, it is composed of two parts of sensor and display instrument, which can also be made into integral type.
Turbine flowmeter turbine flowmeter and volumetric flowmeter, Coriolis mass flowmeter called three types of repetitive, precision products, as one of the top ten types of flowmeter, its products have been developed for many varieties, series of large-scale production scale.
(1) High precision, in all flowmeter, belongs to the most accurate flowmeter;
(2) Good repeatability;
(3) Yuan 0 point drift, good anti-interference ability;
(4) wide range;
(5) Compact structure.
(1) cannot maintain the calibration characteristic for a long time;
(2) Fluid physical properties have great influence on flow characteristics.
The turbine flowmeter is widely used in some of the following measurement objects: Petroleum, organic liquids, inorganic fluids, liquefied gases, natural gas, food, beverages and low temperature fluids in Europe and the United States, the turbine flowmeter in the dosage is second only to the orifice flowmeter of natural meters, only the Netherlands in the natural gas pipelines on the use of more than 2,600 units of various sizes, Pressure from the 0.8~6.5mpa gas turbine flowmeter, they have become excellent gas metering instruments.
