Precession vortex flowmeter should pay attention to the following points in the working environment

The intelligent vortex flowmeter is often referred to as the precession vortex flowmeter. For the precession vortex flowmeter, the first is the scope of application and advantages of this flowmeter. Let's get to know it. Of course, under the influence of the working environment, we should also pay attention to the following points when installing and using: The intelligent vortex flowmeter adopts the newer microprocessor technology, which has strong functions, wide flow range, simple operation and maintenance, convenient installation and use, etc. Its main technical indicators have reached the advanced level of similar foreign products. It is suitable for various gas and liquid measurement in petroleum, chemical, electric power, metallurgy, coal and other industries. Let's take a look at the material selection background of the intelligent precession vortex flowmeter: in some special occasions, the orifice plate flowmeter can no longer meet the basic measurement requirements, and the user begins to choose the precession vortex flowmeter. In the field of natural gas flow measurement, there are often some special users, the specific performance is: the instantaneous flow is small, and the flow fluctuates greatly. If the traditional orifice flowmeter is still used for flow measurement, there is a risk of violating the relevant technical standards. For example, it is required that 'the flow rate in the pipeline should not change with time, or actually only change slightly and slowly with time, once these basic conditions of use are exceeded, the measurement accuracy of the orifice flowmeter will be impossible to talk about; in addition, in this special case, the selection of the display instrument is also a very troublesome matter, if the matching is improper, the indication or It is also unavoidable to record the indication value out of tolerance. Second, the strict control of production management costs is an urgent requirement for the survival and development of modern enterprises. Now, all enterprises are experiencing the severe baptism of the market. The level of production costs will inevitably affect the survival and development of enterprises. Therefore, under the premise of meeting the basic requirements of flowmeters, the choice can save static investment and reduce dynamic costs. The new flow meter has also been put on the agenda of relevant decision makers. The characteristics of the measuring instrument of the intelligent precession vortex flowmeter. Compared with the conventional orifice plate flowmeter, the intelligent precession vortex flowmeter has the following main characteristics: 1. It realizes mechatronics, and no manual duty is required for daily measurement work; 2. The process installation conditions are not harsh, and the upper and lower straight pipe sections of the instrument can be It is greatly shortened and shorter than the orifice flowmeter; 3. The measurement accuracy of the system meets the current trade measurement requirements (≤2%)'>; 4. The flow measurement range is wide (qmax/qminu003d15~20'>), in small Part of the small flow area can work effectively, and the orifice flowmeter cannot be touched; 5. Small size and light weight, easy for offline calibration; 6. The measurement signal can be displayed locally or transmitted remotely as needed; 7. There are no moving parts, so For general measurement, the instrument will not produce mechanical wear; 8. The instrument management personnel do not need to undergo professional training, and the measurement parameters, such as flow, pressure and temperature, can be directly read from the instrument head, and no conversion is required; 9. Only regular Replace the battery of the precession vortex flowmeter (micro-power consumption) and the parameters of the measured medium. The installation precautions of the intelligent precession vortex flowmeter include the following 13 points: (1) The intelligent precession vortex flowmeter can be adjusted according to the flow direction The sign is installed in a vertical, horizontal or any inclined position. (2) When the distance between the pipeline and the vibration source is far or near, the support should be installed on the upper and lower parts of the flowmeter to eliminate the influence of pipeline vibration. (3) The installation position of the intelligent precession vortex flowmeter should have enough space for easy inspection and maintenance, and should meet the environmental requirements. (4) It should avoid the interference of external strong magnetic fields. (5) When installed and used outdoors , should pay attention to cover to avoid the erosion of sunlight and rain, which will affect the service life of the instrument. (6) When testing the pipeline, pay attention to the pressure measurement range of the pressure sensor configured by the precession vortex flowmeter to avoid overpressure damage to the pressure Sensor. (7) Attention should be paid to the influence of installation stress. When installing the flowmeter, the upstream and downstream pipes should be coaxial, otherwise shear stress will occur. When installing the flowmeter, the thickness of the sealing gasket should be considered, or an elastic expansion joint should be installed downstream (8) Welding slag and other sundries in the pipeline should be removed before installing the flowmeter. (9) When putting into operation, the flowmeter of the upper and lower valves should be opened slowly, so as not to damage the spinner due to sudden airflow. (10) When the flowmeter is required for signal remote transmission, it should be connected to the external power supply (8~24) VDC in strict accordance with the requirements of 'electrical performance indicatorsChange the wiring mode of the explosion-proof system, and do not twist the output lead connectors arbitrarily. (12) During the operation of the intelligent precession vortex flowmeter, do not open the back cover at will to change the instrument parameters, otherwise it will affect the normal operation of the flowmeter. (13) ) Regular leak detection on the flange plate of the flowmeter. The above content is the use method and installation working environment of the precession vortex flowmeter that Xiaobian thinks is more useful. Know.
