How to install the intelligent precession vortex flow meter correctly

Abstract: The information on how to install the intelligent precession vortex flowmeter correctly is provided by the excellent flowmeter and flowmeter manufacturers. Intelligent precession vortex flowmeter installation: When the flowmeter is installed, it is strictly forbidden to directly weld the inlet and outlet flanges to avoid burning out the internal parts of the flowmeter. For newly installed or overhauled pipelines, be sure to clean and remove the debris in the pipeline before installation. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the article details on how to install the intelligent precession vortex flowmeter correctly. Installation of intelligent precession vortex flowmeter: When the flowmeter is installed, it is strictly forbidden to directly weld the inlet and outlet flanges to avoid burning out the internal parts of the flowmeter. The newly installed or overhauled pipeline must be cleaned, and the flowmeter can only be installed after removing the sundries in the pipeline. The flowmeter should be installed in a place that is easy to maintain, free from strong electromagnetic field interference, strong mechanical vibration and thermal radiation; the flowmeter should not be used in occasions with frequent interruption of flow and strong pulsating flow or pressure pulsation; when the flowmeter is installed outdoors, the upper part should be installed. There should be a cover to prevent rainwater immersion and scorching sun exposure from affecting the service life of the flowmeter; the flowmeter can be installed at any angle, and the flow direction of the fluid should be consistent with the flow direction marked on the flowmeter; in the pipeline construction, it should be considered to install expansion pipes or corrugations To avoid serious stretching or breaking of the flowmeter; the flowmeter should be installed coaxially with the pipeline, and prevent the sealing sheet and butter from entering the inner cavity of the pipeline; when using an external power supply, the flowmeter must be reliably grounded, and must not be connected to strong electricity. The system shares the ground wire, and the ground wire of the electric welding system shall not be overlapped with the flowmeter during pipeline installation or maintenance. In order not to affect the normal transmission of fluid and facilitate maintenance, it is required to install the bypass pipe as shown in Figure 4, and ensure that the≥3DN, after≥1DN straight pipe section; intelligent precession vortex flowmeter straight pipe section requirements According to the working principle of the precession vortex flowmeter and the flowmeter's requirements for the upstream and downstream straight pipe sections, it is recommended to use the front and rear straight pipe sections listed in the following figure for various upstream resistance parts. The length of the pipe section, and keep the inner wall of the straight pipe section smooth and straight. Precautions for the installation of intelligent precession vortex flowmeter: The sensor can be installed in vertical, horizontal or any inclined position according to the flow direction sign; when the pipeline is long or the distance from the vibration source is close, the support should be installed upstream and downstream of the flowmeter to avoid Eliminate the influence of pipeline vibration; the installation site of the sensor should have enough space to facilitate the inspection and maintenance of the flowmeter, and should meet the environmental requirements of the flowmeter; the interference of external strong magnetic fields should be avoided; when installed and used outdoors, there should be Cover to avoid hot sun exposure and rain erosion, which will affect the service life of the instrument; when testing the pipeline pressure, pay attention to the pressure measurement range of the pressure sensor equipped with the intelligent flowmeter to avoid damage to the pressure sensor due to overpressure. Attention should be paid to the influence of installation stress. The upstream and downstream pipelines of the installation flowmeter should be coaxial, otherwise shear stress will occur. The location where the flowmeter is installed should consider the thickness of the gasket, or install an elastic expansion joint on the downstream side. Welding slag and other debris in the pipeline should be removed before installing the flowmeter. When put into operation, the upstream and downstream valves of the flowmeter should be opened slowly, so as not to damage the spinner due to sudden airflow. When the flowmeter needs to have remote signal transmission, it should be strictly“Electrical performance index”It is required to connect to the external power supply (8~24) VDC, and it is strictly forbidden to directly connect the 220VAC or 380VAC power supply to the signal output port; users are not allowed to change the wiring method of the explosion-proof system and arbitrarily twist each output lead connector; when the flowmeter is running, it is not allowed Open the back cover at will to change the parameters of the instrument, otherwise the normal operation of the flowmeter will be affected; regularly check the leakage at the flange of the flowmeter. The use and replacement of the built-in battery: the battery power display, when the battery display has only one grid left, the user is required to replace the battery within one month; when only the battery shape symbol is displayed, the battery power is exhausted, and the battery must be replaced immediately. How to replace the battery: Open the back cover of the smart flow totalizer, loosen the three screws on the battery cover, unplug the battery socket, take out the battery, replace it with a new battery and reinstall it. The installation requirements of the intelligent precession vortex flowmeter in explosion-proof places: the flowmeter should have reliable grounding, and the explosion-proof grounding should not be shared with the protective grounding of the strong current system. When testing the power supply in the field, it is not allowed to use the AC power grounding. Under any circumstances, the user shall not change the explosion-proof circuit, components and explosion-proof type. The external power supply must be cut off before opening the cover of the converter. The above is the entire content of this article.
