Product description

Flowmeters are divided into differential pressure flow meters, rotor flow meters, throttling flow meters, slit flow meters, volumetric flow meters, electromagnetic flow meters, ultrasonic flow meters, turbine flow meters and vortex flow meters, etc. According to the medium classification: liquid flow meter, gas flow meter, steam flow meter and solid flow meter.

Advantages:

(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.

Disadvantages:

(1) The calibration characteristics cannot be maintained for a long time;

(2) The physical properties of the fluid have a great influence on the flow characteristics.

Application Overview:

Turbine flowmeter is widely used in the following measuring objects: petroleum, organic liquid, inorganic liquid, liquefied gas, natural gas, food, beverage and cryogenic fluid. In Europe and the United States, turbine flowmeter is a natural measuring instrument second only to orifice flowmeter in terms of usage. Holland alone has adopted more than 2600 gas turbine flowmeters of various sizes and pressures ranging from 0.8 to 6.5MPa on natural gas pipelines, they have become excellent natural gas metering instruments.
