5 Reasons for the Output Shake of the Smart Electromagnetic Flow Meter

Abstract: The information on the 5 reasons for the output shaking of the intelligent electromagnetic flowmeter meter is provided by the excellent flowmeter and flowmeter manufacturers and quotation manufacturers. The five reasons for the output shaking of the intelligent electromagnetic flowmeter are as follows: First, the cause of the failure The output shaking can be roughly summarized into five reasons for the failure, which are: (1) The flow itself is fluctuating or pulsating, not actually the electromagnetic flowmeter. Faults, only reflect the truth. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the 5 reasons for the output shaking of the intelligent electromagnetic flowmeter. The five reasons for the output shaking of the intelligent electromagnetic flowmeter are as follows: First, the cause of the failure The output shaking can be generally summarized into five reasons for the failure, which are: (1) The flow itself is fluctuating or pulsating, and it is not essentially the electromagnetic flowmeter. Faults, only reflect the flow conditions truthfully; (2) The end of the pipeline is full of liquid or the liquid contains bubbles; (3) Electrical and magnetic interference such as external stray currents; (4) The physical properties of the liquid (such as uneven liquid conductivity or high (5) The electrode material is not properly matched with the liquid. Second, the inspection procedure checks the flow of the electromagnetic flowmeter output shaking. First, make a preliminary investigation and judgment according to the comprehensive examination process, and then carefully check and try to troubleshoot one by one. The order of inspections listed in the process is as follows: (1) It can be observed or inquired to understand that there is no need for major operations before, that is, easy first and then difficult; The higher one is in the first place; ③ check its own sequential requirements. If a preliminary investigation confirms the causes of several faults behind the feet, detailed inspections can also be made in advance. 1. Start - check whether there is a pulsating flow disturbance source in the piping system of the electromagnetic flow sensor - whether the flow power source is a reciprocating pump or a diaphragm pump. If yes: a. Install air chamber and blocker to slow down the pulsation b. Increase the damping amount of the instrument. If no: check whether the downstream pump valve has hunting vibration? If yes: improve the control characteristics of the control valve. Fluctuating disturbance source? If there is: Eliminate the disturbance source in a targeted manner. If no, please refer to 2. 2. Check whether the liquid in the pipe is full? Does the liquid contain air bubbles?--Set the gas collecting bag and manual exhaust valve downstream of the sensor to facilitate inspection and confirmation. a. Check whether the liquid in the pipe is full? If it is not full: Pay special attention to the position where the sensor is installed horizontally or installed vertically and flows from top to bottom, and change it to a position that can be completely filled, such as a vertical installation that flows from bottom to top Location. b. Does the liquid contain air bubbles? If there are air bubbles: install other separators or automatic exhaust valves upstream of the sensor. If there is no air bubble, please see 3. 3. Check whether the sensor is well grounded? If there is no good grounding: a. The sensor and the adjacent pipeline realize the third grounding (below 100 ohms) b. When connecting to the insulated pipeline or the anti-corrosion lined pipeline, Install grounding rings or grounding short pipes at both ends of the sensor. If the grounding is good, check whether there is interference such as stray current in the pipeline. If there is interference, move the source of interference. If there is no interference, check whether there is a strong magnetic field source such as a high-power transformer near the sensor. If so, change the installation position, the principle is a strong magnetic field source. 4. Check the physical properties of the liquid - whether it is a slurry - whether the liquid conductivity is uniform - whether the liquid conductivity is too low. The above is the entire content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
