Digital vortex flowmeter, digital integrated vortex flowmeter, softened water vortex flowmeter

Description :

LUB-2350 Integrated Vortex Flow MeterIt uses the Karman vortex street principle for flow measurement. When a cylindrical object is vertically inserted into the measuring tube, the fluid naturally alternates between regular vortices on both sides of the object, which is called a Karman vortex street At d/D=0.281, the released vortex is stable. D is the diameter of the pipeline. ）The release frequency of the Karman vortex street is related to the flow velocity of the fluid and the width of the column. The integrated vortex street flowmeter flow transmitter is a 4-20mA analog signal output with strong anti-interference performance, which can be directly connected to PLC or DCS to reduce the risk of trade disputes. There should be sufficient space around the instrument installation point for installation wiring and regular maintenance. In the pipeline measuring steam, to prevent the converter temperature from being too high, at least half of the instrument connecting rod should not be insulated. In order to facilitate observation and wiring, the flowmeter head can rotate 360 degrees in its original position. After adjusting the position, tighten the locking nut. If the installation direction of the flowmeter head is facing downwards, the locking nut must be wrapped and sealed with waterproof tape,Digital vortex flowmeter, digital integrated vortex flowmeter, softened water vortex flowmeterThe vortex flowmeter has no mechanical movable parts, small size, corrosion resistance, stable performance, can directly display the working pressure, temperature, and flow rate of the medium, wide range, and small measurement error. It has been widely used in the production measurement of oil and gas wells and the sales measurement of natural gas. The intelligent vortex flowmeter is a stress type vortex flowmeter that measures flow based on the Karman vortex principle. It has low pressure loss, high sensitivity, simple structure, no movable parts, and high reliability. According to relevant information, by the beginning of 2004, a new situation had emerged in the development and production of vortex flowmeters in China, with more than 200 production enterprises and an annual output of over 30000 units.

　　When a triangular cylindrical vortex generator is set up in the fluid, regular vortices are alternately generated from both sides of the vortex generator, which are called Karman vortices. The vortex columns are asymmetrically arranged downstream of the vortex generator.Integrated vortex flowmeterIt is a volumetric flowmeter that measures the volumetric flow rate, standard condition volumetric flow rate, or mass flow rate of gases, vapors, or liquids based on the K á rm á n Vortex Street principle. And it can be used as a flow transmitter in automation control systems. The steam anti vibration vortex flowmeter applies the principle of fluid oscillation to measure flow rate. When the fluid passes through the vortex flowmeter in the pipeline, two columns of vortices proportional to the flow velocity are alternately generated up and down behind the vortex generator in the triangular column. The release frequency of the vortices is related to the average velocity of the fluid flowing through the vortex generator and the characteristic width of the vortex generator. Later, major domestic instrument manufacturers also participated in this work. In the mid-1970s, Tianjin Industrial Automation Instrument Research Institute and the Automation Research Institute of the Ministry of Metallurgy also successively invested in the research and development of vortex flowmeters, and explosion-proof flowmeters should be used in hazardous sites. Due to the fact that explosion-proof instruments are not allowed to be used in Class 0 hazardous areas, and explosion-proof instruments are not allowed to open the casing with electricity on site for circuit adjustment, users should try to use explosion-proof vortex flow meters as much as possible

　　For the convenience of use, the battery powered local display vortex flowmeter adopts low-power high-tech. It can operate continuously for more than a year with lithium battery power supply, saving the procurement and installation costs of cables and display instruments. It can display instantaneous flow, cumulative flow, etc. on site. Temperature compensation also comes with temperature sensors,Integrated vortex flowmeterIt is possible to directly measure the temperature of saturated steam and calculate the pressure, thereby displaying the mass flow rate of saturated steam. The temperature pressure compensation integrated type is equipped with temperature and pressure sensors, which can directly measure the temperature and pressure of the gas medium for gas flow measurement, thereby displaying the standard volume flow rate of the gas. Digital vortex flowmeter, digital integrated vortex flowmeter, softened water vortex flowmeterNominal diameter (mm): 15, 25, 40, 50, 65, 80, 100, 125, 150, 200, 250, 200, 300 (200-2000 plug-in type) Non standard products can be customized according to user requirements. Vortex flow meters should be avoided from being installed on pipelines with strong vibration as much as possible. If installation is necessary, pipeline fastening devices must be added at the 2D upstream and downstream locations, and anti vibration pads must be added to enhance the anti vibration effect. Ultrasonic testing technology should be applied to introduce ultrasonic vortex flow meters; Beichen Electric Machinery Factory has successfully developed a strain gauge vortex flowmeter using strain detection technology; Eastech launches the second type of vortex flowmeter, which is a vibrating vortex flowmeter using magneto electric detection technology

　　Digital vortex flowmeter, digital integrated vortex flowmeter, softened water vortex flowmeterIt is a stress type vortex flowmeter that measures flow based on the Karman vortex street principle.
