The measurement data relates to the production and management of enterprises and the quality control of products. For the tap water industry, measurement work is particularly important. It not only relates to the economic benefits of the water companies, but also affects the interests of thousands of households. Due to the influence of various factors such as the diameter and length of the conveying pipe and the requirement for measurement accuracy, the water company will have different choices for the flow meter. Then, what problems should be noticed in the selection of tap water flowmeters? Please see the details of the Shunda flowmeters. Problems to be noticed in the use of flow meter selection in the tap water industry The key to using a good flow meter is the selection. At present, there are more than 100 manufacturers of large-diameter flow meters and the models are also varied. Therefore, when choosing the type of flow juice, it is necessary to pay attention to the following points: A verification certificate issued by the national measurement department must be issued, and the on-site installation conditions should meet the specific requirements of the selected flowmeter for the straight section and the selected flowmeter to meet the installation conditions. The following is the water industry in the flow meter selection can refer to the following criteria: 1 According to the diameter of the water pipe diameter size selection In the tap water industry, electromagnetic flowmeters are usually given priority in the selection of flowmeters, while Venturis and reservoirs will be selected for Venturi (durable and maintenance-free); Ultra-large calibers can be selected for ultrasonic flowmeters. Try not to use plug-in type Flow meter. 2 According to the straight section and the water quality tested Under normal circumstances, the electromagnetic flowmeter requires a minimum of 5D for the front pipe section, and 10D for the front straight pipe section of the ultrasonic flowmeter is 20D. 3 Select according to the site's environmental conditions The selected flowmeter must be able to adapt to the actual environmental conditions on the site, such as temperature, humidity, and electromagnetic signal interference. 4 Select according to the specific requirements of the control system Under normal circumstances, the tap water industry requires the flow meter to have a display and flow signal output function. At present, with the wide application of network technologies and computer technologies, control systems now employ a large number of data communication technologies and are more reasonable. There are also differences in flow meter protocols that are used in different communication technologies, such as PROFIBUS, HART, and MOBUS. This requires the tap water industry to consider the specific requirements of the control system when selecting the flow meter to select the appropriate model.
