Abstract: the classification and working principle of volumetric
flowmeter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation.
Volumetric flowmeter, as a kind of mechanical flowmeter is characterized of straight pipe before and after no requirement and high measuring accuracy.
Widely used in oil, such as viscous medium measurement.
1, double rotor flowmeter is the volumetric flowmeter is main varieties, and forms more complete specification.
More flow meter manufacturers choose model price quote you are welcome to inquire, here is the classification and working principle of volumetric flowmeter scale article details.
Volumetric flowmeter, as a kind of mechanical flowmeter is characterized of straight pipe before and after no requirement and high measuring accuracy.
Widely used in oil, such as viscous medium measurement.
1, double rotor flowmeter is volumetric flowmeter is main varieties, in the form of more complete specification, can be used for liquid and gas measurement of various kinds of medium.
2, oval gear flowmeter, flow part of it is mainly composed of two mutually meshing elliptical gear and the shell (
Measuring room)
.
3, waist wheel volume flowmeter, waist wheel also known as volumetric flowmeter type roots volume flowmeter.
Working principle and working process of the flowmeter and the elliptical gear type basic same, the same is rely on import and export fluid pressure difference to produce movement, each week from four parts & other
Measuring space & throughout;
The amount of fluid volume.
The difference is in the waist wheel without teeth, they are not mesh with each other directly, but through the installation outside the housing groups of gear transmission.
4, scraper, fluid drive scraper and the rotor rotation, scraper along the trajectory into a special kind of radially out back.
Every two relative to the distance between the scraper face to a certain value, the scraper rotates in a row, two adjacent scraper, rotor, shell lumen, and formed a fixed measuring room between upper and lower cover plate, the rotor per round, out of four (
Or 6)
Measuring room volume, the volume.
The scraper can be divided into contact with cavity wall is not elastic scraper and rigid scraper, elastic scraper front contact with the cavity wall elasticity, suitable for measuring the liquid containing impurities such as sand;
Rigid scraper with fixed minimum clearance front and the cavity wall, used to clean liquid or liquid with a fine powder impurities.
Rigidity of the scraper can be divided into the concave line structure (
The British AveryHardoll type)
And CAM type (
The Smith)
。
5, rotary piston.
Insert ring piston two layers of cylindrical cylinder shell, the form along with the flow of the liquid ring piston rotating in the shell form, meter diameter 3/4 '~ 100 mm, measurement accuracy is 0.
5%R。
Can be used for the measurement of oil and food.
6 reciprocating piston type.
Piston under the fluid drive, reciprocating motion in the cylinder, volume flow measurement, usually tankers is this type of gas station, traffic is 60 l/min, the measuring accuracy for & plusmn;

6, disc type.
(also called nutation flowmeter
NutatingFlowmeter)
, with the center of the disc of the ball in the measuring room rotation and bobbing nutation (

Sports, entering and discharging liquid, compared with other PDF accuracy is poorer, viscosity influence.
Have production in China to measure oil products, less application.
In North America is more used as a household water meter and industrial water meter.
7, the rotary drum, also known as wet gas meter, is used for measuring gas volume.
Flowmeter shell about half inside sealing liquid (
Water or oil)
, a drum half immersed in the sealing liquid and gas into the rotation, its seal form is no leakage.
Wide range of degrees systematically, stable performance and higher accuracy can be obtained under the careful operation, for & plusmn;

% R, mostly in the laboratory, is used for dissemination or standard table table.
So many displacement meter, the measurement has the advantages of the application in different medium.
General common volumetric flowmeter for the oval gear flowmeter, double rotor flowmeter, waist wheel flow meter and scraper flowmeter.
But volumetric flowmeter than the general digital watch price is expensive, especially large diameter you many times.
Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
