Advantages and Disadvantages of Vortex Flow Meters

Abstract: The advantages and disadvantages of vortex flowmeters are provided by excellent flowmeter and flowmeter manufacturers. The advantages and disadvantages of the vortex flowmeter What are the characteristics and limitations of the vortex flowmeter? The vortex flowmeter is a new type of flowmeter with international advanced level successfully developed based on the principle of Karman vortex flow. The advantages obtained, since seven. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the advantages and disadvantages of vortex flowmeters. The advantages and disadvantages of the vortex flowmeter What are the characteristics and limitations of the vortex flowmeter? The vortex flowmeter is a new type of flowmeter with international advanced level successfully developed based on the principle of Karman vortex flow. The advantages obtained have been rapidly developed since the 1970s. According to relevant data, the proportion of vortex flowmeters used in developed countries such as Japan, Europe and the United States has increased significantly, and it has been widely used in various fields. It will be used in future flow meters. It is the most ideal substitute for orifice flowmeter, and it is also the first choice flowmeter in China. 1. Features of vortex flowmeter: simple and firm structure, no moving parts, high reliability, very reliable long-term operation; simple installation, very convenient maintenance; detection sensor does not directly contact the medium, stable performance and long life; output is consistent with The pulse signal proportional to the flow rate has no zero drift, high precision, and is convenient for networking with a computer; the measurement range is wide, and the range ratio can reach 1:10; the pressure loss is small, the operating cost is low, and it is more energy-saving; The output signal frequency is not affected by the change of the physical properties and components of the fluid, and the instrument coefficient is only related to the shape and size of the vortex generator. The volume flow of the measured fluid does not require compensation, and there is no need to re-calibrate the instrument coefficient after changing accessories. The application range is wide, and the flow of steam, gas and liquid can be measured; 2. Limitations of vortex flowmeter: Vortex flowmeter is a kind of velocity flowmeter, and the stability of vortex separation is affected by the flow velocity distribution, so it has a The straight pipe section has certain requirements, generally '10D in the front and 5D in the rear'; when measuring liquid, the upper limit flow rate is limited by the pressure loss and 'cavitation' phenomenon, generally 10m/s. When measuring gas, the upper limit flow rate is limited by the change of the compressibility of the medium, and the lower limit flow rate is limited by the Reynolds number and the sensitivity of the sensor. Generally, the flow rate range of gas is 10-70m/s, and the flow rate of steam is 8-50m/s; stress type The vortex flowmeter is more sensitive to vibration, so when installing the vortex flowmeter in the pipeline with more vibration, the pipeline must have certain damping measures; the stress type vortex flowmeter uses piezoelectric crystal as the detection sensor, so it is affected by temperature The general long-term working temperature is -40℃～+350℃ and -10℃～+250℃. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Advantages and Disadvantages of Vortex Flow Meters'
