How to analyze the on-site calibration of sewage flowmeter

With the rapid development of China's economy and industrial level, the discharge of various sewage flow meters, especially industrial sewage, has also increased significantly. The treatment charges after sewage discharge are also becoming more and more market-oriented. The sewage treatment plant collects sewage treatment fees according to the volume of sewage discharged by enterprises. Accurate metering of various flow meters for metering wastewater discharges is becoming increasingly important. Because the company's sewage pipeline is relatively fixed, the disassembly of the flowmeter is time-consuming and laborious, and it is difficult for the enterprise to send the inspection. The on-site inspection of the flowmeter not only saves the enterprise's time, but also reduces the inspection cost of the enterprise. Therefore, the on-site inspection of the flowmeter for sewage metering has been more and more welcomed by enterprises, and has become the development trend of such flowmeter detection.
First, the environment is different
I can't operate in a small space with my existing flow standard device. At present, due to the cumbersome disassembly of the flow meter, the inspection and consumption cost a lot of manpower and material resources, and the flow meter used by many enterprises for sewage metering is in an unchecked state.
Second, technical capability analysis and project prospects
In order to ensure the interests of both the production enterprise and the sewage treatment plant, help the enterprise to reduce sewage discharge and protect the ecological environment. At the same time, we must carry out the inspection on the customer's on-site pipeline seriously and responsibly. After investigation, we understand the actual use of the sewage flowmeter. The situation and the actual difficulties of using the enterprise, found that although the accuracy of the electromagnetic flowmeters they use is generally 0.5, but the actual use of enterprises does not need such high precision, generally can achieve (1-2)% accuracy can be completely To meet the customer's requirements, the flowmeters used by the company are generally uninterrupted. Once disassembled, the entire company's production will be affected, and frequent disassembly will have a certain negative impact on its accuracy. To meet the measurement requirements of such enterprises, we found out that they are currently using a portable ultrasonic flowmeter to perform on-site inspection of such flowmeters by searching for information and consulting with peers.
The ultrasonic flowmeter can be directly clamped on the outside of the pipeline, and the corresponding field parameters can be input, and the working condition of the online flowmeter can be detected in real time, and the flowmeter on-site detection can be realized conveniently and quickly.
At the same time, we know that the calibration accuracy of this type of instrument is 1.0% (the data can be corrected by the calibration data in actual use), and the repeatability is better than 0.2%. These can basically meet the needs of online on-site inspection. The on-site inspection project of the sewage flow meter that I intend to carry out saves valuable time for the enterprise and greatly reduces the inspection cost of the enterprise. Especially because the accurate measurement of the sewage flow meter protects the interests of both the production enterprise and the sewage treatment plant, Helping enterprises reduce sewage discharge and protect the ecological environment will form good social and economic benefits.
