Analysis of Accuracy Factors Affecting Orifice BURKERT Flowmeter At present, BURKERT flowmeter has various flow measuring instruments used in different destinations, and its measurement accuracy is generally valued by people. The accuracy of the orifice flowmeter is determined by its structure, measurement principle, and use. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the details of the article on the analysis of the accuracy factors affecting the orifice BURKERT flowmeter. Analysis of Accuracy Factors Affecting Orifice BURKERT Flowmeter At present, BURKERT flowmeter has various flow measuring instruments used in different destinations, and its measurement accuracy is generally valued by people. The accuracy of the orifice flowmeter is determined by its structure, measurement principle, the properties of the fluid to be measured, the environmental conditions of use and the level of manufacturing technology. However, many objective factors in the verification process and in the use process will also affect the accuracy of the orifice flowmeter, and even greatly reduce the accuracy of the orifice flowmeter, affecting the normal use of the orifice flowmeter, and deviating from the original intention of the selection. The main influencing factors are as follows. One: The actual use accuracy of the BURKERT flowmeter flow standard device BURKERT flowmeter must be calibrated under various conditions, and an appropriate flow standard device must be used. The actual use accuracy of the flow standard device for verification is higher than that of the orifice flowmeter. For the instrument submitted for inspection, it is necessary to ask whether the verification equipment, method and accuracy meet the requirements. 2: The flow condition of the measured fluid The fluid flowing in the pipeline or open channel has different flow conditions, such as laminar flow, turbulent flow, pulsating flow, uneven flow, etc. In particular, the use of Bernoulli's theorem to develop orifice flowmeters requires steady flow and uniform flow velocity distribution, such as orifice flowmeters. If there are obstacles in the pipeline, it will cause drastic changes in the flow, resulting in non-negligible errors in the measurement results of the orifice flowmeter. When the orifice flowmeter is installed, the straight pipe section is generally required to be the first 10 and the last 5, and the use of elbows, valves, etc. is required to be minimized. Three: The physical properties of the measured medium Up to now, each orifice flowmeter is used normally under specific conditions, and no orifice flowmeter can measure the flow of any medium under any conditions. Flow measurement is a complex measurement. When measuring flow with orifice flowmeter, it is not suitable to measure the flow of fluid with large viscosity. When measuring steam, the pressure and temperature signals should be collected in real time into the flow meter for correction. Ultrasonic orifice flowmeter cannot measure gas. When the measured fluid contains larger and more solid particles, it will greatly affect the measurement accuracy. Therefore, when the accuracy of the orifice flowmeter decreases, attention should be paid to whether the physical properties of the measured fluid have changed. Four: Correct installation and use of orifice flowmeters The installation and use of BURKERT flowmeters are closely related to its measurement accuracy, especially those with orifice flowmeters where the detection element is directly located in the flowing fluid. If the concentricity between the orifice plate and the pipeline in the orifice plate flowmeter is not good, errors will occur, and the error can reach 100% in serious cases. Therefore, according to the different requirements for installation conditions, various orifice flowmeters must be strictly treated differently. Only by following the installation conditions can the measurement accuracy of the orifice flowmeter be guaranteed. The accuracy of the BURKERT flowmeter is class 0.5, class 1, while the accuracy in actual use is 1.5 or 2. The orifice plate is greatly affected by the front and rear straight pipe sections, and the installation requirements are also relatively high, and the range ratio should not be too large (usually 3:1). Since the fundamental reason that affects the measurement accuracy of the orifice flowmeter is whether the geometry and flow dynamics of the throttling device deviate from the design standards, systematic verification and maintenance must be done regularly during the use process. If the parameters of the working conditions change, it should be corrected in time. A fully compensated ground flow totalizer can be used to reduce the measurement error and ensure the measurement accuracy. Orifice flowmeter is a kind of instrument with strict requirements from design, manufacture to installation and use, and mistakes in any link will produce large errors. Therefore, if the standard regulations are strictly followed, its accurate measurement is guaranteed. The repeatability of the orifice flowmeter is lower than that of other orifice flowmeters (vortex orifice flowmeter, ultrasonic orifice flowmeter, and electromagnetic orifice flowmeter). The reason is that the output signal is an analog value and is susceptible to interference. In particular, the differential pressure pipeline is easy to cause interference and fluctuation of the signal. It is precisely because the repeatability is not high, so it affects the improvement of its accuracy. The above is the whole content of this article.
