Abstract: the intelligent vortex precession flowmeter scale how to correctly install the information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Intelligent vortex precession flowmeter installation: meter installation, it is strictly prohibited in the import and export directly to where the flange welding, so as not to burn out flowmeter internal parts. For the new pipe must be cleaned after installation or maintenance, can remove the impurities in the pipeline before the installation. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the intelligent vortex precession flowmeter scale article details how to properly installed. Intelligent vortex precession flowmeter installation: meter installation, it is strictly prohibited in the import and export directly to where the flange welding, so as not to burn out flowmeter internal parts. For the new pipe must be cleaned after installation or maintenance, can remove the impurities in the pipeline before the installation of flow meter. Meter should be installed in easy maintenance, strong electromagnetic interference, strong mechanical vibration and the influence of thermal radiation place; Flowmeter is unfavorable with frequent interruptions in the flow and strong pulsating flow or pressure pulsation occasions; Meter outdoor installation, should be the upper cover, to prevent rain water immersion and strong sunlight affect the service life of the meter; Can install at any Angle of the flow meter, the flow of fluid shall conform to the flow direction of logo on the meter; In pipeline construction, should consider to install expansion tube or bellows, lest cause serious tension or the meter; Meter shall be installed with coaxial pipe, and prevent the seal and butter into the pipe inner cavity; When external power is adopted, the meter must be reliable grounding, may not be common ground with heavy current system, the pipe installation or maintenance, can't leave the ground and flowmeter lap welding system. In order not to affect the normal fluid transmission and easy to maintain, requests the shown in figure 4 by-pass pipe installation, and ensure the former & ge; After 3 dn, & ge; 1 dn straight pipe; Intelligent vortex precession flowmeter straight pipe requirements according to the working principle of vortex flow meter and flow meter of precession of straight pipe upstream or downstream demand, for a variety of upstream resistance, the recommended length of straight pipe before and after the listed below, and keep straight pipe inner surface smooth and flat. Intelligent vortex precession flowmeter installation note: sensor according to the flow marks can be tilted in vertical, horizontal, or any location on the installation; When the line is longer or close from the vibration source, support should be installed at upstream or downstream of flowmeter, in order to eliminate the influence of the pipeline vibration; Sensor installation location should have enough space, so that the flow meter inspection and maintenance, and shall meet the environmental requirements of flowmeter; Should avoid the disturbance of external magnetic field; When used in outdoor installation, should have cover, avoid the strong sunlight and rain erosion, affect the service life of the instrument; Pipeline pressure test, the intelligent flowmeter should be paid attention to the configured pressure pressure sensor measuring range, in order to avoid over-voltage damage pressure sensor. Installation should be paid attention to stress, the influence of upstream and downstream piping should be coaxial installation flowmeter, otherwise it will produce shear stress. The location of the installation flowmeter should consider the thickness of the sealing gasket, or install a elastic expansion joints in the downstream side. Should be clear before installation flowmeter in the pipeline welding slag and other sundry. When in operation, should slowly open flowmeter, downstream of the valve, in order to avoid air flow is too sharp and blunt bad on the moment. When the meter requires signal remote transmission, should be strictly in accordance with & other; Electrical performance & throughout; Request access to external power ( 8 ~ 24) VDC, forbidden in direct access to 220 vac or 380 vac signal output power; Users shall not change the connection mode of explosion protection system itself and any budge each output pin connector; Meter run, not allowed to open the rear cover change instrument parameters, otherwise the normal operation of the meter; Regularly check meter flange leakage situation. The use of the built-in battery and replace: battery showed that when the battery shows only one, asks the user to replace the battery in a month. Show only the battery symbol shape, the battery has run out, must immediately replace the batteries. Battery replacement method: open of intelligent flow totalizer. especially back cover, loosen the three screw the battery cover, remove the battery socket and remove the battery and reinstall after changing the new battery. Explosion-proof site installation requirements: intelligent vortex precession flowmeter flowmeter should be reliable grounding, explosion-proof ground should not be Shared with protective earthing system. Field test power, are not allowed to use the ac power grounding. In any case, the user may not change the explosion-proof circuit, components and explosion-proof type. Must cut off the power converter before we open the lid converter above is all there is in this article, you are welcome to inquire me factory flowmeter selection, quotation, etc.
