Briefly describe the use and maintenance of vortex flowmeter

Abstract: Briefly describe the use, maintenance and repair information of vortex flowmeters are provided by excellent flowmeter and flowmeter manufacturers. The vortex flowmeters produced by Weinan and Shunda flowmeter manufacturers are mainly used for flow measurement of medium fluids in industrial pipelines. They are characterized by small pressure loss, large measuring range, high precision, high reliability, and low maintenance. A more advanced and ideal flow. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is a brief description of the use, maintenance and repair of vortex flowmeters. The vortex flowmeter produced by the flowmeter manufacturer is mainly used for the flow measurement of the medium fluid in the industrial pipeline. It is characterized by small pressure loss, large measuring range, high precision, high reliability and small maintenance. It is a relatively advanced , The ideal flow meter. The following technology introduces in detail what should be paid attention to when using the vortex flowmeter? 1. The main problems: ① The indication is inaccurate for a long time; ② There is no indication all the time; ③ The indication fluctuates in a large range, and the reading cannot be read; ⑤ There is no indication when the flow rate is small; ⑧ The indication is ok when the flow rate is large, but the indication is inaccurate when the flow rate is small; ⑦ The indication change cannot keep up with the flow rate change; 2. Analysis and solution of main problems 1. Problems in model selection. Some vortex sensors have a large selection due to changes in process conditions in caliber selection or after design selection.—In order to improve the measurement accuracy, the actual selection should choose the smallest diameter possible. The reasons for this are mainly related to the problems ①, ③, and ⑥. 2. Installation problems. The main reason is that the length of the straight pipe section in front of the sensor is not enough, which affects the measurement accuracy. The reason for this is mainly related to problem ①. 3. The reason for the parameter setting direction. Due to wrong parameters, the instrument indication is wrong. The wrong parameters make the calculation of the full-scale frequency of the secondary instrument wrong. The reasons for this are mainly related to problems ① and ③. The similar full-scale frequency makes the indication inaccurate for a long time, and the actual full-scale frequency greatly affects the calculated full-scale frequency, which makes the indication fluctuate in a large range and cannot be read, and the inconsistency of the parameters on the data affects the final determination of the parameters, and finally passed Recalibration combined with mutual comparison to determine the parameters solves this problem. 4. Secondary instrument failure. There are many faults in this part, including: there is a disconnection on the circuit board of the instrument, the display of the individual digit of the range setting is broken, and the display of the individual digit of the K coefficient setting is broken, making it impossible to determine the range setting and K coefficient setting. Part of the reason is mainly related to problems ① and ②. By fixing the corresponding failure, the problem is solved. 5. Four-way line connection problem. On the surface of some circuits, the circuit connection seems to be very good. After careful inspection, some connectors have actually been loose, causing the circuit to be interrupted. Although some connectors are tightly connected, the fastening screws are fastened to the wire sheath due to the problem of the auxiliary line, which also makes the circuit breaker. Interruption, this part of the reason is mainly related to problem ②. The corresponding line problems are solved, and the existing problems are also solved accordingly. 6. The circuit has no indication due to the fault of the flat shaft cable of the secondary instrument. Due to long-term operation and the influence of dust, the flat shaft cable is faulty, and the problem can be solved by cleaning or replacing the flat shaft wire. 7. For the problem ⑦, the main reason is that the second instrument shows that the fixing screw of the head coil is loose, which causes the head to sink, the friction between the pointer and the case is large, and the action is not working. By adjusting the head and fixing it again, the problem is solved accordingly. 8. Use of environmental issues. Especially for the sensor part installed in the ground well, the circuit board is damp due to the high ambient humidity. This part of the reason is mainly related to problems ② and ②. Through the corresponding technical improvement measures, some sensors with high environmental humidity have been re-separated from the probe part and the conversion part, and a separate sensor has been used, so the working environment has been improved. Recently, this part of the instrument runs well. 9. The reason why question 8 is raised separately is that this problem has affected the analysis and solution of the problem for a long time. Since Dongfang Chemical Factory does not have the K coefficient calibration conditions, the K coefficient can only be based on the information provided by the manufacturer. Some changes have caused the K coefficient to be different in several data provided.—It affects the solution of the problem. By looking for conditions to re-calibrate, or through repeated modification and comparison, the unified instrument parameters are finally determined. 3. In order to better use the vortex flowmeter, the summary is as follows: 1. Regularly check the grounding and shielding conditions to eliminate external interference. Sometimes the indication problem is due to interference. 2. The probes of the vortex flowmeter should be cleaned regularly. During the inspection, it was found that the detection holes of individual probes had been blocked by dirt, or even wrapped in plastic sheets, which affected the normal measurement. 3. The management of instrument data should be paid enough attention to facilitate future work. 4. Install the probe in a humid environment. It should be dried once regularly, or treated with moisture-proof. Since the probe itself is not treated with moisture, it will affect the operation after being affected by moisture.
