Abstract: The information on how to correctly purchase and use the precession vortex flowmeter is provided by the excellent flowmeter and flowmeter manufacturers. Precession vortex flow sensor is currently widely used in petroleum, chemical, electric power, metallurgy, urban gas supply and other industries to measure the flow of various gases. The accurate use of precession vortex flow sensor must comply with the following five requirements, so as to ensure the measurement. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the article details on how to correctly purchase and use precession vortex flowmeters. Precession vortex flow sensor is currently widely used in petroleum, chemical, electric power, metallurgy, urban gas supply and other industries to measure the flow of various gases. The accurate use of precession eddy flow sensor must comply with the following five requirements, so as to ensure the measurement accuracy precision. 1. Precise selection of precession vortex flowmeter is widely used in natural gas, gas and other industries, with stable performance, accurate measurement, and convenient installation. When it has been determined to choose a precession vortex flowmeter, the next is the flow sensor. The selection of standards and their kits is critical. In a word, choose well to use well. For this reason, two basic principles should be grasped in the selection process; namely: one must ensure the accuracy of use, and the other must ensure the safety of production. To do this, it is necessary to implement three selection parameters, namely, the maximum, minimum and common instantaneous flow rates in the near and long term, the planned pressure of the measured medium, and the operating pressure. 2. Calibration before use On the one hand, considering the current on-site verification of this type of flow sensor, there are still some difficulties. In addition, if the purpose of the purchase is to prepare the flow sensor to be used in more important measurement occasions, such as commercial measurement of large flow or measurement points where measurement conflicts are more prominent, and the application site does not have the conditions for online calibration of flow , then in this case, it is a little too early to easily conclude that all the performance of the flow sensor is qualified only by a factory certificate provided by the manufacturer at the time of purchase. Therefore, in order to ensure the reliability and accuracy of the measurement results of the flow sensor in the future operation process, it is necessary to send the flow sensor to the part with the verification ability and talent for a system verification within the full flow range before the official installation. . 3. Do a good job of technical equipment Although this kind of flow sensor does not have too many special requirements for technical equipment and application environment, any type of flow measurement surface has such a commonality, that is, to prevent vibration and high temperature environment from accompanying the flow state as much as possible Disturbing elements, keeping the inner wall of the straight pipe section before and after the flow sensor smooth and straight, ensuring that the measured medium is a clean single-phase fluid, etc. 4. Strengthen the management of the precession vortex flowmeter in the later stage Although it has the characteristics of various automatic treatment functions and micro-power consumption, it still needs to be strengthened after it is put into operation. For example, in order to ensure the accuracy and reliability of the long-term operation of the flow sensor, it is necessary to regularly calibrate the system, copy the header data, replace the medium parameters, and check the battery status, flow sensor coefficients and lead seals from time to time. 5. Pay attention to internal protection If the measurement cavity of the flow sensor and its components need to be regularly inspected or cleaned due to air pollution or other reasons, then one point must be paid special attention: for the same standard precession vortex flow sensor, its vortex Central components such as generators and guides cannot be exchanged. Otherwise, the external measurement coefficients must be recalibrated and the temperature and pressure sensors equipped with them must be systematically calibrated. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'How to Properly Purchase and Use Precession Vortex Flow Meters'
