Several Reasons for the Decrease of the Accuracy of the Turbine Flow Meter

Abstract: The information on the reasons for the decline of the accuracy of the turbine flow meter is provided by the excellent manufacturers of flow meters and flow meters. Turbine flowmeter has obvious advantages such as compact structure, intuitive and clear reading, high reliability, no interference from external power supply, lightning resistance, low cost, etc. It is widely used in petroleum, chemical, metallurgy, papermaking and other industries to measure liquid volume instantaneous flowmeter and body. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the reasons for the decline in the accuracy of turbine flowmeters. Turbine flowmeter has obvious advantages such as compact structure, intuitive and clear reading, high reliability, no interference from external power supply, lightning resistance, low cost, etc. It is widely used in petroleum, chemical, metallurgy, papermaking and other industries to measure liquid volume instantaneous flowmeter and total volume. I saw some people on the Internet asking again, during the use of the turbine flowmeter, it was found that the accuracy decreased, so what is the reason? 1. There are generally some impurities in the medium, which will wear the bearings and shafts, so that the gap between the two will increase, the dynamic balance of the moving parts will be destroyed, the speed will drop, or the dirt will enter the gap, which will increase the movement resistance. , the speed drops. All of these reasons cause the display value of the instrument to decrease and negative errors to appear, which is unfavorable to the fluid supplier. 2. The fibrous or viscous impurities in the fluid are attached to the rotating part of the flowmeter, which increases the rotating resistance, reduces the indication value of the instrument, and causes negative errors, which is unfavorable to the fluid supplier. 3. Changes in fluid temperature and pressure may cause the liquid in the pipeline to escape the air contained in it, or because the pressure in the pipeline is lower than the saturated vapor pressure of the fluid, part of the liquid may turn into steam, or the negative pressure of the medium may cause the external air. The gas is sucked into the pipeline, and these gases flow with the liquid to be measured, causing the indication value of the instrument to increase, resulting in a positive error, which is unfavorable to the demand side of the fluid. 4. The working environment is relatively bad, for example, electromagnetic field interference, dust, high temperature, vibration, humidity, etc., may cause the malfunction or failure of the turbine flow sensor, which directly causes the indication error of the turbine flowmeter. The error may be positive or negative. value, which may not be obvious, or it may be completely ineffective. For the above phenomenon, when it is more serious, problems can be found from the comparison of the working status of the process, and it is easy to take corresponding measures. However, in the early stages of the problem, the problem cannot be detected without taking special measures. The maintenance of the turbine flowmeter should pay attention to the following points: 1. When using, the measured medium should be kept clean and free of impurities such as fibers and particles. 2. When the turbine flow sensor starts to use, the sensor should be filled with medium slowly, and then the outlet valve should be opened (the valve should be installed at the back end of the flowmeter). It is strictly forbidden for the sensor to be impacted by high-speed fluid when there is no medium. 3. The maintenance period of the turbine flow sensor is generally half a year. When overhauling and cleaning, be careful not to damage the parts in the measuring chamber, especially the impeller. When assembling, please pay attention to the positional relationship between the guide and the impeller. 4. When the turbine flow sensor is not in use, the internal medium should be cleaned, and after drying, a protective cover should be added at both ends of the sensor to prevent dust from entering, and then stored in a dry place. 5. The filter should be cleaned regularly, and the internal medium should be cleaned when not in use. Like the sensor, add a dust cover and store it in a dry place. 6. Before the sensor is installed, blow the impeller by mouth or by hand to make it rotate quickly to observe whether there is a display, and then install the sensor when there is a display. If there is no display, check the relevant parts and troubleshoot.
