Installation of ABG Sewage Flow Meter and Design of Online Detection Device

Abstract: The design information of ABG sewage flow meter installation and online detection device is provided by excellent flow meter and flow meter manufacturers and quotation manufacturers. In order to reduce pollution, save water and reduce emissions, it is necessary to strictly measure and control domestic water, industrial water, circulating water and discharged sewage. The measurement of flow is occupied in the total amount control, quota management and petrochemical production and process control of water resources. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following are the details of the ABG sewage flowmeter installation and design of the online detection device. In order to reduce pollution, save water and reduce emissions, it is necessary to strictly measure and control domestic water, industrial water, circulating water and discharged sewage. The measurement of flow plays an important role in the total control of water resources, quota management and petrochemical production and process control. The main water supply plant for circulating water in the coal chemical plant area, the normal operation of the water supply device of this plant is very important to the production and environmental protection of the whole plant. Sewage treatment capacity and treatment quality are important indicators of the water supply device. If the treatment capacity is low, it cannot meet the water requirements of the whole plant, and if the treatment quality is low, it cannot meet the discharge requirements. To investigate the water output capacity and economic benefits of mine water, three flow indicators are mainly considered, namely, the inflow of mine water, the outflow of clarified water and the outflow of sludge. In this process, the use of sewage flow meters is particularly important. Before using the sewage flowmeter for measurement, it is necessary to have a systematic understanding of some knowledge of the sewage flowmeter and the matters in use. The following will tell you some knowledge about the use of sewage flowmeters. First of all, as a flow measurement instrument, before using the measurement correctly, you must know how to install it correctly. The following will share with you some matters about the installation process of sewage flowmeters: Do you already have a comprehensive understanding and understanding of the installation of sewage flowmeters through the above explanation? Next, I will describe the design of the online detection device of the sewage flowmeter. For the design of this installation, we comprehensively refer to the national metrological verification routine (1-3) to determine the diameter limit, flow limit, accuracy level of the standard table, the installation method of the standard table and the selection of other components of the installation. The design ideas of several key components of the installation are now described in key points: (1) In order to ensure that the inner and outer walls of the installed experimental pipeline are lubricated and flat, the material is uniform, and the aesthetics and applicability are also considered. All the pipeline materials are made of stainless steel. Also for the convenience of on-site use, the set of installation adopts a detachable and movable structure. (2) Because the installation of the ultrasonic flowmeter should meet the length distinction between the upstream and downstream straight pipe sections is 10D and 2D (D is the inner diameter of the pipe), the length of the upstream straight pipe section is required to be longer. If the length of the installation is too long, it will be difficult to operate on site. Therefore, we installed a rectifier in front of the upstream straight pipe section. The effect of the rectifier can adjust the installation of the flow field distribution in the pipeline. It can shorten the length of the pipeline, quickly adjust the unstable state of the fluid flow rate distribution, and ensure the ultrasonic flow rate. accuracy of meter measurements. (3) In order to adjust the flow quickly and accurately, we use a V-shaped flow adjustment valve to adjust the flow; in order to load and unload the tested flowmeter conveniently and labor-savingly, a manual lifting platform is installed on the lower surface of the flowmeter carrying the mass; in order to prevent the pipeline from appearing negative After installation, set a back pressure elbow in the straight pipe section after installation. (4) The specification table for installation selects an external clip-on ultrasonic flowmeter with an accuracy grade of 0.5. In order to ensure the accuracy and reliability of the specification table, the specification table needs to be verified on time during the installation of the water flow specification. For your correct measurement, you should pay attention to the following requirements when choosing the position on the pipeline: (1) The sensor can be installed on either a straight pipeline or a horizontal or inclined pipeline, but the center line of the two electrodes is required to be in the horizontal state. (2) The medium should flow in the full tube at the installation position to avoid the more full tube and gas from adhering to the electrode. (3) For liquid-solid two-phase fluid, it is best to use vertical installation to make the lining of the sensor wear evenly and prolong the service life. (4) When the medium at the installation position of the flowmeter is not full of pipe, the method of raising the half rear-end pipeline of flow rate can be adopted to make the pipe full. It is strictly forbidden to install the flowmeter at the highest point of the pipe and the water outlet. (5) Modify the installation method of the pipeline: When the flow rate of the medium does not meet the requirements, a smaller diameter flowmeter should be selected. At this time, a tapered pipe with a different diameter should be used or part of the pipeline should be modified to make it the same diameter as the sensor, but straight forward and backward. The pipe section must meet at least: the front straight pipe section≥5DN, straight back pipe≥2DN. (DN is the pipe diameter) (6) The front and rear straight pipe sections are in front of the flowmeter≥5DN, backend≥2DN. The above is the whole content of this article.
