Abstract: Information on installation precautions for elbow flowmeters is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Elbow flowmeter is a differential pressure flow device, which is widely used for flow measurement of liquid, gas and steam in electric power, heat, metallurgy, steel, chemical, machinery, textile, paper, pharmaceutical, food, public utilities and other industries. First, the flow of the L-shaped elbow. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the installation precautions for elbow flowmeters. Elbow flowmeter is a differential pressure flow device, which is widely used in the flow measurement of liquid, gas and steam in electric power, heat, metallurgy, steel, chemical, machinery, textile, paper, pharmaceutical, food, public utilities and other industries. 1. When installing the L-shaped elbow flowmeter sensor: 1. First, intercept two straight pipe sections with the same pipe diameter as the pressure elbow, and the length is more than 1 times the diameter. 2. On a platform (or flat ground) with better conditions, weld the two straight pipe sections intercepted to the pressure-taking elbow, in a 90-degree vertical state, 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. 2. The flow sensor of the S-shaped elbow is connected with the process pipeline by flange, which can be connected with the process pipeline in a horizontal space state according to the flow direction of the sensor mark. 3. 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 straight pipe section at the rear end should be greater than 2 times the diameter. Commissioning of elbow flowmeter: Inspection before commissioning 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. 4. After the above checks are correct, turn on the power supply of the secondary instrument. The elbow flowmeter is easy to install, wear-resistant and maintenance-free. As a primary measuring element, the elbow sensor can be installed on the pipeline by direct welding, and there will be no headaches such as leakage after one welding is completed. The tube sensor is maintenance-free. It should be emphasized that the reason why the elbow sensor can be installed by welding is that the elbow sensor is not sensitive to wear, and the trace wear of long-term operation has little effect on the measurement performance of the elbow sensor, which is different from the welded orifice plate. There is a fundamental difference. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
