Precautions for use of precession vortex gas flow meter

Abstract: Precautions for the use of precession vortex gas flow meters are provided by excellent flowmeter and flowmeter manufacturers. Any kind of metering instrument has its particularity, and the intelligent precession vortex gas flowmeter is no exception. In order to make this kind of gas flowmeter better serve the flow measurement work, the technicians from Jiangsu Xudong Instrument Factory have many years of on-site practical experience. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the article details of the precautions for the use of precession vortex gas flowmeters. Any kind of metering instrument has its particularity, and the intelligent precession vortex gas flowmeter is no exception. In order to make this kind of gas flowmeter better serve the flow measurement work, many years of on-site practical experience of technicians from Xudong Instrument Factory show that the following precautions should be paid enough attention by the relevant management and use departments. 1. Pay attention to instrument selection. Once the instrument type has been selected (for example, an intelligent precession vortex gas flowmeter), the selection of the instrument size and its supporting components is critical. In a word, you can use it well when you choose it. To this end, two basic principles should be grasped in the selection process; namely: one must ensure the accuracy of use, and the other must ensure production safety. To do this, three selection parameters must be implemented, namely, the maximum, minimum and common instantaneous flow rates in the near and long term (mainly used for selecting the size and specifications of the instrument), and the design pressure of the measured medium (mainly used for Nominal pressure rating of the selected instrument), working pressure (mainly used to select the pressure rating of the instrument pressure sensor). 2. Perform pre-use calibration. On the one hand, considering that there are still some difficulties in the field verification of such instruments at present. In addition, if the purchase intention is to use this instrument in more important measurement occasions, such as large-flow trade measurement or measurement points with prominent measurement disputes, and the application site does not have the conditions for online calibration of flow, then In this case, it is too early to easily judge that all the performances of the watch are qualified based on 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 instrument in the future work process, it is necessary to send it to the department with the verification ability and qualification for a system verification within the full flow range before the formal installation. 3. Do a good job in process installation. Although this kind of flowmeter does not have too many special requirements for process installation and use environment, any type of flow measurement instrument has such a commonality, that is, to avoid vibration and high temperature environment with flow state interference components (such as compressors) , separator, pressure regulating valve, large and small heads and manifolds, elbows, etc.), keep the inner wall of the straight pipe section before and after the instrument smooth and straight, and ensure that the measured medium is a clean single-phase fluid, etc. 4. Strengthen post-management. Although this kind of instrument has the characteristics of various automatic disposal functions and low power consumption, it still needs to strengthen the management after it is put into operation. For example, in order to ensure the accuracy and reliability of the long-term operation of the flowmeter (to avoid unexpected outages and data loss), it is necessary to regularly calibrate the system (every 1 to 2 years), transcribe the header data (every day or week), Change the media parameters (monthly or quarterly) and check the battery condition from time to time, check the meter coefficient and lead seal, etc. 5. Pay attention to internal maintenance. If the measuring cavity and its components of the instrument need to be inspected or cleaned regularly due to air pollution or other reasons, then one point must be paid special attention: for the precession vortex flowmeter of the same specification, its vortex generator, guide fluid, etc. The core components cannot be interchanged, otherwise, the metering coefficient of the meter must be re-calibrated and the temperature and pressure sensors equipped with it 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. 'Precautions for the use of precession vortex gas flow meters'
