How to ensure the accuracy of turbine flow meter measurement

Abstract: The information on how to ensure the accuracy of turbine flow meter measurement is provided by excellent flow meter and flow meter manufacturers. How to ensure the accuracy of turbine flowmeter measurement Turbine flowmeter is currently widely used in petroleum, chemical, electric power, metallurgy, urban gas supply and other industries for various gas flow measurement sensors, the correct use of turbine flowmeter to follow the following five points . More flowmeter manufacturers select models and price quotations. You are welcome to inquire. The following is the article details on how to ensure the accuracy of turbine flowmeter measurement. How to ensure the accuracy of turbine flowmeter measurement Turbine flowmeter is a sensor widely used in petroleum, chemical, electric power, metallurgy, urban gas supply and other industries to measure various gas flow. The correct use of turbine flowmeter should follow the following five requirements , so as to ensure the accuracy of the measurement. 1. Pay attention to the selection of instruments. When the type of flow sensor has been selected, the selection of the specifications of the flow sensor 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 post-management Although this kind of flow sensor 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 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 turbine flowmeter of the same specification, the vortex generator The core components such as , guide fluid, etc. cannot be interchanged, otherwise, the metering coefficient of the instrument must be re-calibrated and the temperature and pressure sensors equipped with 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. 'How to ensure the accuracy of turbine flow meter measurement'
