How to use precession vortex flowmeter correctly
2021-05-17
Precession vortex flowmeter is widely used in crude oil, chemical plants, power engineering, metallurgical industry, city gas supply and other technical specialties steam flow measurement sensors. When the liquid enters the outer diffusion section, the swirling flow returns and begins to rotate twice, resulting in gyro picture vortex precession. The precession frequency is positively related to the total flow rate and is not affected by the chemical properties and relative density of the liquid.
How to apply precession vortex flowmeter correctly
1. Pick carefully
Precession vortex flowmeter is widely used in gas, gas and other fields, the function is stable, accurate measurement is accurate, and the machine equipment is convenient. It is very important to select the specifications of air flowmeter and support point components under the clear criteria for the use of a whirl steam flowmeter.
2. Calibration before application
On the one hand, it is still difficult to fully consider the on-site certification of such air flowmeters. In addition, if the purpose of the purchase is to prepare this type of air flow meter in advance for critical accurate measurement sites, such as the accurate measurement of large flow transactions or the accurate measurement of the measurement point prominence.
3. Do technical work well
Although this type of air flow meter does not have many special requirements for technical equipment and office environment, all the appearance of flow measurement has such a correlation, that is, to avoid vibration and high temperature natural environment as far as possible, and adhere to the straight inner cavity of the right and left nozzle section of the air flow meter before and after the wetting, so as to ensure that the measured substance is a clean single-phase electric liquid.
