Aister full technical support gas turbine flowmeter use method
2021-07-02
Gas turbine flowmeter is currently widely used in petroleum, chemical, electric power, metallurgy, urban gas supply and other industries of various gas flow measurement sensors, the correct use of gas turbine flowmeter to follow the following five requirements, so as to ensure the accuracy of measurement.
1. Attach importance to instrument selection
In the case that the type of flow sensor has been selected, the selection of the flow sensor specification and its supporting components is very important. In a word, choose well to use well. Therefore, two basic principles should be grasped in the selection process; That is, first, to ensure the accuracy of use, and second, to ensure production safety. To do this, it is necessary to implement three selection parameters, namely, the size of the near and long term and the common instantaneous flow rate, the design pressure of the measured medium, and the working pressure.
2. Standard calibration before use
On the one hand, considering that there are still some difficulties in the field verification of this kind of flow sensor. In addition, if the intention of the purchase is to prepare the flow sensor to be used in more important measurement occasions, such as large flow of trade measurement or measurement disputes more prominent measurement points, and the use of the site does not have the flow online calibration conditions, then in this case, It is too early to easily determine the full performance of the flow sensor based on a factory qualification 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 this verification ability and qualification for a system verification within the full flow range before the formal installation.
3.do a good job of process installation
Although this kind of flow sensor does not have too many special requirements for the process installation and use environment, any kind of flow measuring instrument has such a common feature, that is, to avoid vibration and high temperature environment with off-flow interference elements, to keep the inner wall of the front and back straight pipe of the flow sensor smooth and straight, and to ensure that the measured medium is a clean single-phase fluid.
4. Strengthen late management
Although this kind of flow sensor has a variety of automatic handling functions and micro-power consumption characteristics, it still needs to strengthen management after operation. For example, in order to ensure the accuracy and reliability of the long-term work of the flow sensor, the system calibration should be regularly carried out, the head data should be copied, the media parameters should be replaced, and the battery condition should be checked from time to time, the flow sensor coefficient and the lead seal should be checked.
5. Pay attention to internal maintenance
If the measurement chamber of the flow sensor and its components need to be inspected or cleaned regularly due to temperament dirt or other reasons, special attention must be paid to: For gas turbine flowmeters with the same specifications, the core components such as vortex generator and flow guide body cannot be exchanged, otherwise, the meter measurement coefficient 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 reduce a lot of problems in the future, which is particularly important for continuous production manufacturers.
