New understanding and correct installation of elbow flow meter

Abstract: The latest cognition and correct installation information of elbow flowmeters are provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Elbow flowmeter is a differential pressure flow measurement system, which is an instrument for measuring the flow of medium in the pipeline using the principle of fluid centrifugal force. Can be used to measure liquid, gas, steam various media. It consists of elbow sensor, elbow flowmeter host, differential pressure transmitter and some. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the latest understanding of elbow flowmeters and the details of the correct installation article. The elbow flowmeter is a differential pressure flow measurement system, which is an instrument that uses the principle of fluid centrifugal force to measure the flow of the medium in the pipeline. Can be used to measure liquid, gas, steam various media. It consists of elbow sensor, elbow flowmeter host, differential pressure transmitter and some pipeline valve components. When temperature and pressure compensation are required for flow measurement, pressure transmitter and temperature transmitter should also be equipped. The elbow flowmeter has a wide measurement range, high repeatability, no additional pressure loss, small on-site maintenance, low operating costs, and can realize temperature and pressure online compensation. There are two types of elbow sensors according to the installation method: S-shaped elbow sensors installed on straight pipes, and L-shaped elbow sensors installed at natural turns. According to the processing method, there are two types of ordinary push sensors and machined sensors. The elbow flowmeter also plays an important role in the flow measurement system. It is an instrument that uses the principle of fluid centrifugal force to measure the flow of the medium in the pipeline. It is also a differential pressure type. Flow measurement system. The main features of the elbow flowmeter: 1. Simple installation and maintenance, good reliability; 2. Low requirements for straight pipe sections, 5D in the front and 2D in the rear; 3. Strong anti-vibration performance, wide measurement range, high accuracy, and long service life; 4. It can be used in harsh environments such as high temperature, high pressure, dust, vibration, and humidity; 5. The wear of the pipe has little effect on the measurement accuracy, and it can be connected to industrial automation systems. These unique features are difficult to achieve with other flow meters, so they bring potential for its development. The following mainly introduces the matters that we should pay attention to when installing the lower elbow flowmeter: 1. When installing the L-shaped elbow flowmeter: 1. First, intercept two straight pipe sections with the same pipe diameter as the pressure elbow, and the length is between 1 times the diameter or more. 2. On a platform (or flat ground) with better conditions, weld the two straight pipe sections intercepted with the pressure-taking elbow in a vertical state of 90°, and ensure the welding quality. 3. Weld the prefabricated pipeline on the rack and the process pipeline. 4. Weld the elbow sensor and the process pipeline to make it work in a horizontal space state as much as possible. When the site does not have horizontal installation conditions, it can be installed in a vertical space state. Second, the S-shaped elbow flow sensor and the process pipeline are connected by flanges, which can be connected with the process pipeline in a horizontal space state according to the flow direction of the sensor mark. When installing the elbow flow sensor, the length of the straight pipe section at the front end should be greater than 5 times the diameter, and the length of the straight pipe section at the rear end should be greater than 2 times the diameter. Inspection before work 1. Check whether the piping, installation and wiring of each transmitter (including differential pressure, pressure and temperature transmitters) are correct. 2. Check whether all welding interfaces and threaded joints are tight and leak-free. 3. Check whether the wiring of the secondary instrument is correct, whether the wiring with each transmitter is correct, and focus on checking the position of the power connector. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'New Cognition and Correct Installation of Elbow Flow Meters'
