How to maintain the precession vortex flow meter

Abstract: The information on how to maintain the precession vortex flowmeter is provided by the excellent flowmeter and flowmeter manufacturers. 1. The principle of precession vortex flowmeter: The precession vortex flowmeter has built-in pressure, temperature and flow sensors, high safety performance, compact structure and beautiful shape, and can display the instantaneous flow and cumulative flow of temperature and pressure on the spot; it adopts a new signal processing amplifier and independent . More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the article details on how to maintain the precession vortex flowmeter. 

Firstly. The principle of the precession vortex flowmeter: 

the precession vortex flowmeter has built-in pressure, temperature and flow sensors, high safety performance, compact structure, beautiful shape, local display of temperature, pressure, instantaneous flow and cumulative flow; new signal processing amplifier and unique The filter technology effectively eliminates the interference signals generated by pressure fluctuations and pipeline vibrations, greatly improving the anti-interference ability of the flowmeter, making the small flow have wonderful stability; the function of real-time data storage, no matter what the situation, It can ensure that the internal data will not be lost, and the reliability can be retained; the power consumption is extremely low, and it can be powered by the internal battery for a long time, which is an ideal local display instrument without external power; 180 degrees of free rotation, easy installation. 

Secondly, the daily maintenance of the precession vortex flowmeter: 

1.Improper installation and vortex flowmeters maintenance efficiency will not only affect the measurement accuracy and other functions, but also make the instrument work incorrectly and even damage the instrument in severe cases: when moving and hoisting the electromagnetic flowmeter, it should be The slings are placed on the two neck positions of the flowmeter flange. Do not put pipe rods in the measuring tube for hoisting, so as to avoid damage to the lining. At the same time, the wiring socket of the screwed customized vortex flowmeter should be prevented from being damaged by collision; it is necessary to ensure that the flowmeter The center and the center of the process pipeline are the same, and the ground wire is connected well, otherwise it will cause errors.  

2.It should be placed in a dry and ventilated place, away from wet and prone to water accumulation, avoid sun and rain, avoid strong vibration as much as possible, and avoid equipment with strong electromagnetic fields, such as large motors, large transformers, etc.; in order to make the precession vortex flowmeter reliable To work on the ground, not to be disturbed by external parasitic potential, there should be a good separate ground wire, do not connect the ground wire to the common ground wire of the motor or other equipment. The precession vortex flowmeter generally does not require daily vortex flowmeter maintenance efficiency, but when the measured medium is easily adhered or scaled on the inner wall of the electrode and the measuring tube, the inner wall of the measuring tube and the electrode must be cleaned regularly, and the lining electrode should not be damaged. 

3.When the precession vortex flowmeter fails, check whether the medium in the measuring tube is full, whether the lining and electrodes are scaled, whether the cable connection is reliable, whether the excitation coil is short-                  circuited or open, and whether it is insulated from the ground; Whether the medium leaks, whether the upstream and downstream valves are affected, whether the installation location is suitable, whether the nearby environment            interferes with the flowmeter, and whether the converter is operating normally.   

Thirdly. Installation requirements of precession vortex flowmeter: 

any type of flow instrument has its installation characteristics, and precession efficient vortex flowmeter is no exception. In order to make the instrument better serve the flow measurement work, the following aspects should be paid attention to Matters should arouse sufficient attention from the relevant management and use departments. 

1. Pay attention to instrument selection. The type of instrument has been selected (for example, in the case of an intelligent precession vortex flowmeter, the selection of instrument specifications and its supporting components is very important. For this reason, the selection process should be mastered. There are two basic principles; namely: one must ensure the accuracy of use, and the other must ensure the safety of production. To do this, it is necessary to implement three selection parameters, namely the maximum, minimum and commonly used instantaneous flow in the near and long term (mainly The size and specification of the selected instrument) the design pressure of the measured medium (mainly used for the nominal pressure level of the selected instrument) The working pressure (mainly used for the pressure level of the selected instrument pressure sensor) 

2, followed by automatic compensation and The compression factor is automatically corrected. It can also directly detect the standard volume of gas or the mass flow of saturated steam. The precession vortex flowmeter adopts advanced microcomputer technology and high-performance integrated chips. The precession vortex gas flowmeter can detect the temperature and pressure of the medium. .Using advanced micro-power high-tech, the power consumption of the whole machine is low. The flowmeter can be operated with temporary power supply from the internal battery, and can also be operated with external power supply. 

3. Because the precession vortex flowmeter is a velocity type flowmeter , the fluid accelerates the vortex flow through the throttling break, and pressure loss will occur. Therefore, the following problems should be avoided in use: 1) The measurement medium is well guaranteed to be a single Newtonian body. If there are many impurities in crude oil and trace particles, it should be Separate and filter before measuring, otherwise the measured value will be greater than the actual value. 2) The selection of the flowmeter should be based on the actual flow of the medium, rather than the diameter of the installed pipeline, which is very important.

The use and installation of mass flow meter is compared with most other systems for managing the rosemount vortex flow meter maintenance efficiency and no doubt mass flow meter have won the race so many times.
