Scraper Flowmeter Is Wear-Resistant And Anti-Interference, Providing Stable Measurement Of Industrial Fluids
The rotor flowmeter is a high-precision volumetric flow measurement instrument that measures the volume of fluid by the cooperation of the rotor and the metering chamber.
Inside a circular cavity, there is an eccentrically installed rotor (cam). Several radial slots (usually two pairs or more) are opened on the rotor, and a freely sliding scraper is installed in each slot.
We can compare the paddle flowmeter with the several types introduced earlier:
| Characteristics | Elliptical gear | Oval gear | Twin rotor | Paddle |
|---|---|---|---|---|
| Principle | Direct gear meshing | Non-contact oval gear + synchronous gear | Non-contact helical rotor + synchronous gear | Sliding paddle + eccentric rotor |
| Motion mode | Pulsating, with impact | Relatively smooth | Extremely smooth and continuous | Very smooth |
| Vibration and noise | Large | Medium | Extremely small | Extremely small |
| Accuracy | High | Very high | Extremely high | Extremely high |
| Pressure loss | Large | Medium | Small | Medium - Small |
| Cost | Low | Medium | High | Medium - High |
| Core image | Economical and practical | Reliable settlement expert | Top performance | Gentle and precise "gentleman" |
The scraper flowmeter is often used for liquids of high value and requiring precise measurement due to its high accuracy and stability, especially in the petrochemical industry.
The scraper flowmeter is an outstanding representative of volumetric flowmeters that pursue high precision and stable operation. Through the ingenious design of eccentric rotors and sliding scrapers, it achieves continuous, gentle and precise measurement of fluids. Although its structure is relatively complex and the cost is high, it remains a trusted core device in fields with extremely high requirements for data accuracy and equipment reliability, such as crude oil trade and refined oil product measurement. Its stability makes it stand out in advanced application scenarios that require low noise and low vibration.
