Application and Characteristics of Precession Vortex Gas Flow Meter

Abstract: The information on the application and characteristics of the precession vortex gas flow meter is provided by the excellent flow meter and flow meter manufacturers. Gas flowmeters include gas turbine flowmeters, orifice flowmeters, Verabar flowmeters, V-cone flowmeters, metal tube rotameters, vortex flowmeters, precession vortex flowmeters, delta bar flowmeters, etc. Among them, the precession vortex flow sensor is currently widely used. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the application and characteristics of the precession vortex gas flowmeter for details. Gas flowmeters include gas turbine flowmeters, orifice flowmeters, Verabar flowmeters, V-cone flowmeters, metal tube rotameters, vortex flowmeters, precession vortex flowmeters, delta bar flowmeters, etc. Among them, the precession vortex flow sensor is a sensor widely used in various gas flow measurement in petroleum, chemical, electric power, metallurgy, urban gas supply and other industries. The correct use of the precession vortex flow sensor must follow the following five requirements, so as to ensure the measurement accuracy. 1. Instrument selection is very important. When the type of flow sensor has been selected, the selection of flow sensor specifications and its supporting components is very important. 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 commonly used instantaneous flow rates in the near and long term, the design pressure of the measured medium, and the working pressure. 2. Carry out pre-use calibration On the one hand, considering that there are still some difficulties in the field verification of this type of flow sensor. In addition, if the purchase intention is to use this kind of flow sensor 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, In this case, it is too early to easily determine that all the performances of the flow sensor 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 flow sensor in the future work process, it is necessary to send the flow sensor 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 flow sensor 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 as much as possible. Interfering 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. Fourth, strengthen the management of the later stage Although the precession vortex flowmeter has the characteristics of various automatic disposal functions and micro 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 flow sensor, it is necessary to regularly calibrate the system, copy the meter data, replace the medium parameters, check the battery status from time to time, check the flow sensor coefficient and lead seal, etc. 5. Pay attention to internal maintenance If the measuring 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 precession vortex flow sensor of the same specification, its vortex The core components such as the generator and the conducting body cannot be interchanged. Otherwise, the metering coefficient must be re-calibrated and the temperature and pressure sensors attached to it must be systematically calibrated. If the five requirements of flow sensor selection, calibration, process installation, post management and internal maintenance are well grasped, the use of sensors will be reduced a lot in the future, which is especially important for continuous production manufacturers. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
