Scale advantages and vortex flowmeter selection installation key consideration

Abstract: the scale advantages and vortex flowmeter selection installation focus on information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Vortex street flowmeter strengths do you know? Vortex street flowmeter selection would you? Vortex street flowmeter selection installation key consideration? Improper selection flow meter, flow measurement not for sure. But the flow measurement is a complex technology, and there are many different kinds of flow meters. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a scale advantages and vortex flowmeter selection installation articles focus on details. Vortex street flowmeter strengths do you know? Vortex street flowmeter selection would you? Vortex street flowmeter selection installation key consideration? Improper selection flow meter, flow measurement not for sure. But the flow measurement is a complex technology, and there are many different kinds of flow meters, even for a certain application, choose a suitable flow meter becomes a highly technical work, need to carefully and thoroughly before making their zui eventually choose to consider and weigh many factors related to the measurement problem. Vortex flowmeter is based on the principle of karman vortex street and successfully developed a new type of flowmeter, because it has the advantages of other flowmeter it too got rapid development since the 70 s. According to introducing, Japan, Europe and the United States and other developed countries now use the sharp rise in the proportion of vortex flowmeter, has been widely used in various fields, will be dominant in the future flow meters, is the ideal substitute of orifice meter. Vortex street flowmeter advantages in detail: (1) simple structure and firm, have no moving parts, long running very reliable; (2) maintenance is very convenient, low cost of installation; (3) sensor is not direct contact with the medium, stable performance and long service life; (4) the output is proportional to the flow of the pulse signal, no zero drift, high precision, and convenient and computer networking; 5. Wide measuring range, range ratio of 1:10; 6 small pressure loss, low operating cost, more energy saving; All landowners in a certain range of Reynolds number, the output signal frequency is not affected by fluid physical properties, and composition change, instrument coefficient only involved in the body shape and size of the vortex, fluid volume flow measurement without compensation, after changing accessories need to calibration instrument coefficient; End application range is wide, gas and liquid flow can be measured; Pet-name ruby verification cycle is 2 ~ 4 years. Vortex street flowmeter selection installation key consideration: (1) meter, vortex flowmeter is a kind of speed stability affected by the velocity vortex separation, so it to straight pipe has certain requirements, usually after 10 d, 5 d; (2) to measure the liquid, the limit velocity of pressure loss and the corrosion phenomenon, generally is 0. 5～8m/s； (3) measuring gas, restricted by medium compressibility change limit velocity, Reynolds number and lower velocity sensor sensitivity limit, steam is 8 ~ 25 m/s; (4) the stress vortex flowmeter is sensitive to vibrate more, so the vibration of the larger pipe installation flow time, pipeline must have certain shock absorption measures; (5) stress vortex street flowmeter using piezoelectric crystal as detection sensor, so its restricted by temperature, is commonly - 40～+300℃。 Vortex flowmeter is vulnerable to vibration interference, well-designed vortex flowmeter can through hardware and digital signal processing to exclude interference, and the stability of the signal is obtained. Vortex street flowmeter installation need long straight pipe before and after a big hassle, some manufacturers can offer within the flowmeter reducing design, greatly reduces the user specifically MenWei vortex flowmeter with the demand of the straight pipe. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
