What are the reasons for the decline in the accuracy of the liquid turbine flow meter during use?

Abstract: What are the reasons for the decline in the accuracy of liquid turbine flowmeters during use? The excellent flowmeter and flowmeter manufacturers and quotation manufacturers provide you with information. Liquid turbine flowmeter is a precision flow measuring instrument, which can be used to measure the flow and total amount of liquid together with the corresponding flow totalizer. Liquid turbine flowmeters are widely used in measurement and control systems in petroleum, chemical, metallurgy, scientific research and other fields. match. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the article details of the reasons for the decline of the accuracy of liquid turbine flowmeters during use. Liquid turbine flowmeter is a precision flow measuring instrument, which can be used to measure the flow and total amount of liquid together with the corresponding flow totalizer. Liquid turbine flowmeters are widely used in metering and control systems in petroleum, chemical, metallurgy, scientific research and other fields. Liquid turbine flowmeters with sanitary fittings can be used in the pharmaceutical industry. 1. There are usually some impurities in the medium, which will wear the bearings and shafts, which will increase the gap between the two, the dynamic imbalance of the moving parts will be destroyed, the speed will drop, and the dirt may enter the gap, which will increase the movement resistance. , the speed drops. These reasons all cause the display value of the instrument to decrease. 2. Changes in fluid temperature and pressure may cause the liquid in the pipeline to escape and the atmosphere contained in it can cause part of the liquid to become vapor because the pressure in the pipeline is lower than the saturated vapor pressure of the fluid. , it is also possible that the external gas is sucked into the pipeline due to the negative pressure of the medium, and these gases flow with the measured liquid, causing the meter indication value to increase, showing a positive defect, which is beneficial to the demand side of the fluid. 3. The fibrous or viscous impurities in the fluid are attached to a small part of the flowmeter's movement, which increases the resistance to migration and transformation, resulting in a decrease in the indication value of the meter, negative deviations, and unfavorable effects on the fluid supplier. 4. The working conditions are relatively simple, for example, electromagnetic field disturbance, dust, high temperature, vibration, humidity, etc., may cause the wrong action or failure of the turbine flow sensor, which directly causes the display value of the turbine flowmeter to be defective. It may be negative, it may not be obvious, or it may take effect completely. For the above symptoms, when the comparison is serious, a title can be created from the comparison of the process and work status, and it is easy to take corresponding measures. However, in the early stages of the problem, the headline problem cannot be discovered without taking special measures. Haines Automation Instrumentation is a professional manufacturer of electromagnetic flowmeters, turbine flowmeters, vortex flowmeters, magnetic flap level gauges, thermocouples, thermal resistances, bimetal thermometers and pressure gauges of various specifications, etc., as well as the production of various As a manufacturer of non-standard flowmeters, the company has advanced management level, modern professional production equipment, and accurate calibration devices. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
