Analyze the measurement accuracy of wastewater rotor flow meters from multiple perspectives

Project Overview

　　With the continuous development of industry and urbanization, wastewater treatment has become an integral part of modern society. However, in the process of sewage treatment, it is very important to accurately measure the flow rate of sewage. Sewage rotor flowmeter is a kind of flowmeter widely used in the sewage treatment industry at present, but its measurement accuracy is affected by many factors. In this paper, we will analyze the measurement accuracy of the sewage rotor flowmeter from a variety of perspectives.

　　First, the principle of introduction

　　Sewage rotor flowmeter is a mechanical flowmeter, its principle is through the sewage through the measuring device within the rotating impeller, calculated by the volume flow of sewage. The flowmeter structure is simple, easy to operate, is currently one of the most widely used flowmeter in the sewage industry.

　　Second, the measurement accuracy by the factors affecting

　　1. The accuracy of the flowmeter itself: the accuracy of the sewage rotor flowmeter depends on its own manufacturing accuracy, including the manufacturing accuracy of the rotating impeller, measuring device manufacturing accuracy. Different brands and models of sewage rotor flowmeter precision may be different.

　　2. The impact of the fluid state: the fluid state of sewage will have a greater impact on the measurement accuracy. For example, the particulate matter in the sewage may block the rotating impeller, resulting in measurement deviation; the foam in the sewage will also affect the measurement accuracy.

　　3. The impact of the flowmeter installation position: the installation position of the sewage rotor flowmeter will also have an impact on the measurement accuracy. If the flowmeter is installed in the wrong location, such as in the pipeline bends or branches, may lead to the flowmeter's measurement value deviation is large.

　　4. Flowmeter environment: the use of sewage rotor flowmeter environment will also affect the measurement accuracy. For example, if the flowmeter is in a high temperature, low temperature environment, may affect the performance of the measurement device; if the flowmeter is in a corrosive environment, may lead to damage to the measurement device.

　　Third, how to improve the measurement accuracy

　　1. The choice of the flowmeter itself: choose to manufacture high precision, high brand awareness of the sewage rotor flowmeter can improve the measurement accuracy.

　　2. Fluid state control: sewage treatment process can take some measures, such as the installation of filters in front of the flowmeter, control the fluid state of sewage, to avoid particulate matter or foam into the flowmeter, thereby improving the measurement accuracy.

　　3. Optimization of the installation position of the flowmeter: In the installation of the flowmeter, should choose a suitable location, try to avoid installation in the pipeline bends or branches. At the same time, attention should also be paid to maintaining the stability of the pipeline to avoid vibration due to pipeline and affect the measurement accuracy.

　　4. Flowmeter use of environmental control: flowmeter use of the environment should be kept dry, clean and stable. If the flowmeter is in a high temperature, low temperature environment, should take appropriate thermal insulation, cooling measures; if the flowmeter is in a corrosive environment, should be used in corrosion-resistant materials.

　　Fourth, the conclusion

　　In summary, the sewage rotor flowmeter is a widely used flowmeter, but its measurement accuracy is affected by a variety of factors. In order to improve the measurement accuracy, the sewage rotor flowmeter with high manufacturing precision and high brand awareness should be selected, the fluid state of the sewage should be controlled, the installation position of the flowmeter should be optimized, and the flowmeter should be kept in a stable environment. Through these measures, the measurement accuracy of the sewage rotor flowmeter can be effectively improved to ensure the accuracy and stability of the sewage treatment process.
