Technical characteristics of LUGB vortex flowmeter

Abstract: The technical characteristics information of the LUGB vortex flowmeter is provided by the excellent flowmeter and flowmeter manufacturers and quotation manufacturers. With the rapid development of modern measurement technology, various types of flowmeters emerge in an endless stream, the measurement accuracy is continuously improved, the scope of use is expanded, and the installation and maintenance are becoming more and more simple. The LUGB vortex flowmeter introduced in this paper is widely used because of its wide measurement range and high measurement accuracy. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the technical characteristics of the LUGB vortex flowmeter for details. With the rapid development of modern measurement technology, various types of flowmeters emerge in an endless stream, the measurement accuracy is continuously improved, the scope of use is expanded, and the installation and maintenance are becoming more and more simple. The LUGB vortex flowmeter introduced in this paper is widely used in the measurement of water, steam, compressed air and other media in industrial production due to its wide measurement range and high measurement accuracy. This paper discusses the technical characteristics and application of this type of instrument from the aspects of instrument structure, working principle and field application. 1 Structural composition and working principle as shown in Figure 1: The vortex flowmeter is composed of a vortex generating body (triangular column), a detection head, a meter body, a connecting pillar, and a detection amplifier. Fig. 1 The composition of vortex flowmeter LUGB type vortex flow sensor is a kind of flow sensor designed and manufactured by applying Karman vortex principle and modern electronic technology. It is suitable for the measurement of liquid, gas and steam flow in various industries, and can measure turbid liquids containing impurities and tiny particles. When the fluid to be tested flows through the vortex generator, two rows of vortices are alternately generated on both sides of the rear of the generator, forming a“Vortex Street”as shown in picture 2. The frequency of occurrence of the vortex is proportional to the velocity of the fluid, and it conforms to the following formula under certain conditions: where: f: vortex occurrence frequency St: Strouhal number V: flow velocity d: width of the vortex generator Figure 2 Vortex The vortex generates alternating pulsating pressure at the rear of the vortex generator, which is converted into an electrical signal by a piezoelectric signal sensor, and converted into a pulse or standard signal output after being processed by a transmitter. 2 Technical features (1) Wide flow measurement range, high measurement accuracy and small pressure loss. Nominal diameter DN10~DN500. (2) Simple structure, no rotating parts, reliable operation, good durability and long service life. (3) The measurement accuracy is not affected by fluid pressure, viscosity and density. Widely used and industrial measurement, the accuracy level reaches 0.5. (4) Strong resistance to environmental vibration. The measurable temperature is up to +380℃. (5) Signal output current +-4~20mA, pulse signal, HART protocol, etc., which are widely used. (6) Suitable for gas, liquid, steam and other media. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
