Characteristics and Application of VACORDA Vortex Flowmeter

Characteristics of VACORDA vortex flowmeter:
① The anti vibration performance is particularly good, with no zero drift and high reliability. Through a large amount of waveform analysis and spectrum analysis of vortex street flowmeter for a long time, plus Zui’s excellent probe shape, wall thickness, height, probe rod diameter and the matching piezoelectric crystal, advanced CNC lathe is used for processing to ensure the processing of technical parameters such as coaxiality and smoothness, with special processing, Thus zui largely overcomes the common problem that the inherent self oscillation frequency of vortex flowmeter affects the signal.
② The sensor of the intelligent vortex street flowmeter has strong universality, so that the sensor has good interchangeability. Advanced numerical control equipment is used to process the meter body and vortex generator of the sensor to ensure the processing accuracy, so that the components (especially the vortex generator) have strong universality, so that the repeatability and accuracy of the sensor will not be affected by the replacement of components; It can generate strong and stable vortex signal.
③ Simple and firm structure, no movable parts, high reliability, easy to use and maintain.
④ The detection element is not in contact with the medium, and its performance is stable. The sensor with long service life is installed separately with the detection probe and the vortex generator, and the high-temperature resistant piezoelectric crystal is sealed in the detection probe, so it is not in contact with the measured medium. Therefore, the vortex flowmeter has the characteristics of simple structure, good versatility and high stability.
⑤ Output pulse signal or analog signal in direct proportion to the flow, no zero drift, high precision, convenient for networking with computers
⑥ Wide measuring range, measuring range ratio up to 1:10
⑦ The vortex flowmeter does not need compensation when measuring the volume flow. The signal output by the vortex flowmeter is actually linear with the flow rate, that is, proportional to the volume flow. The purpose of pressure and temperature compensation is to obtain the density of the fluid. The mass flow is obtained by multiplying the volume flow. If the volume flow of the gas is measured, compensation is not required.
⑧ Small pressure loss. Use a DN50 vortex flowmeter to measure the flow of combustible gas. If the Zui large flow in the pipeline Qmax = 200m3/h, the pressure loss of the sensor is: △ P = 1.08 × 10-6 ρ v2(kPa)= 0.605 KPa
⑨ Within a certain Reynolds number range, the flow characteristics are not affected by fluid pressure, temperature, viscosity, density and composition, but only related to the shape and size of the vortex generator.
⑩ It has a wide range of applications, and the flow of steam, gas and liquid can be measured.
Application of VACORDA vortex flowmeter:
This flowmeter can be widely used for measuring the flow of water supply and drainage, industrial circulation, sewage treatment, oil and chemical reagents, compressed air, saturated and superheated steam, natural gas and various media in large, medium and small pipelines.
