How to choose the Precession Vortex Flowmeter correctly? How to use Precession Vortex Flowmeter correctly?
Precession vortex flow sensor is currently widely used in the fields of petroleum, chemical industry, electric power, metallurgy, urban gas supply and other fields to measure various gas flow. The accurate application of Precession Vortex flow sensor should comply with the following five requirements, so as to ensure the accuracy of measurement.
?
1. Precise selection
?
After the vortex flow meter and its matching device, it is necessary to select the swirling flow meter and its matching device, that is, to determine the performance of the swirling flow meter and its supporting device, it is necessary to select the vortex flow meter and its matching device. In the process of selection, two basic principles should be grasped, one is to ensure the operation accuracy, the other is to ensure the safety of production. In order to achieve this, it is necessary to carry out three selection parameters, namely, the maximum, minimum and common instantaneous flow in the near future and in the long term, the planning pressure of the measured medium, and the operation pressure.
?
2. Calibration before use
?
On the one hand, considering the current on-site verification of this kind of flow sensor is still difficult. In addition, the purpose of this kind of flow sensor is to use it in important measurement occasions, and the application site does not have the conditions of flow online calibration. In this case, it is too early to easily determine whether all the performance of the flow sensor is qualified only by a piece of paper 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 organization with the verification ability in this respect before the formal device for a system verification within the full flow range.
?
3. Do a good job in technical installation
?
Although this kind of flow sensor does not have much special requirements for technical devices and application environment, there is a common feature in any kind of flow measurement surface, which is to prevent vibration and high temperature environment from disturbing the components with the flow separation state, to keep the inner wall of straight pipe section before and after the flow sensor smooth and straight, and to ensure that the measured medium is a clean single-phase fluid, etc.
?
4. Strengthen the later management
?
Although the Precession Vortex flowmeter has a variety of active disposal functions and micro power consumption features, 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 flow sensor for a long time, it is necessary to regularly calibrate the system, record the meter head data, replace the medium parameters, check the battery condition from time to time, check the flow sensor coefficient and lead seal, etc.
?
5. Pay attention to internal protection
?
? ? If it is necessary to check or clean the measuring chamber and its components of the flow sensor regularly due to dirty gas quality or other reasons, special attention must be paid to one point, that is, for the same standard Precession Vortex flow sensor, the central components such as vortex attack body and flow guide body can not be exchanged, otherwise, it is necessary to calibrate the external metering coefficient from the beginning and transfer the temperature and pressure of its matching belt The sensory system was calibrated.

The above is the introduction of Shanghai Cixi on how to correctly select the Precession Vortex flowmeter. I hope it can help you. If you still have related product problems, you can call the page for consultation! The company provides 24-hour service!
