The main features are:
High measurement accuracy, wide flow range, and good repeatability;
B rotates smoothly, with no pressure fluctuations or vibrations in the fluid inside the pipeline;
The accuracy is less affected by changes in the viscosity of the measured medium;
The single shell structure is simple, with a small volume and light weight; The double shell structure avoids deformation of the measuring chamber due to high pressure, ensuring measurement accuracy. The inner shell components can also be extracted for maintenance, pipeline flushing, line cleaning, and pressure testing;
e. Various counters and transmitters can be equipped as needed to achieve local indication or remote transmission of electrical signals;
f. The fluid state does not affect the measurement accuracy, and there is no need for straight pipe sections before and after the flowmeter, reducing land occupation and costs.
Scope of use: Mainly used for commercial measurement of non corrosive liquids such as crude oil, gasoline, coal, diesel, chemicals, and food.
Working principle and measurement range of scraper flowmeter
The working principle of a scraper flowmeter is to rotate the scraper in the fluid, push the fluid to the measurement chamber, and calculate the flow rate by measuring the volume change inside the chamber. Due to its ability to measure various viscous fluids, the scraper flowmeter has a relatively wide measurement range. However, the specific values of the measurement range will be affected by various factors such as fluid properties, pipeline size, and scraper design.
- Fluid properties: The viscosity, density, temperature, and other characteristics of the fluid directly affect the measurement accuracy and range of the scraper flowmeter. High viscosity fluids may increase the rotational resistance of the scraper and reduce measurement accuracy; And temperature changes may lead to changes in fluid properties, thereby affecting the measurement range.
- Pipeline size: The diameter and length of the pipeline directly affect the velocity and volume of the fluid passing through the scraper flowmeter. Generally speaking, the larger the diameter of the pipeline, the slower the fluid passes through, and the corresponding measurement range increases.
- Scraper design: The shape, material, and size parameters of the scraper also affect its rotational performance and measurement range. Reasonable scraper design can reduce rotational resistance, improve measurement accuracy and range.
Application of Scraper Flow Meter in Different Industries
Scraper flow meters are widely used in industries such as chemical, petroleum, pharmaceutical, and food due to their unique measurement principles and wide range of applications. In these industries, scraper flow meters can accurately measure the flow rate of various viscous fluids, providing reliable data support for the production process.
Precautions for selecting and using scraper flow meters
In order to ensure the measurement accuracy and reliability of the scraper flowmeter, the following points should be noted during the selection and use process:
- Select the appropriate scraper flowmeter model and specifications based on actual needs and fluid characteristics.
- When installing a scraper flowmeter, it is important to ensure that the pipeline size matches the scraper flowmeter to avoid inaccurate measurements caused by too fast or too slow fluid velocity.
- Regularly maintain and calibrate the scraper flowmeter to ensure its measurement accuracy and stable performance.
- Pay attention to the operation status of the scraper flowmeter, promptly detect and handle abnormal situations, and avoid affecting the normal operation of the production process.
In summary, the measurement range of the scraper flowmeter is affected by various factors, but through reasonable selection and use, we can fully leverage its measurement advantages and provide reliable data support for industrial production.
