â‘ The anti-vibration performance is particularly good, no zero drift, and high reliability. Through a large number of waveform analysis and spectrum analysis of the vortex flowmeter for a long time, coupled with the best probe shape, wall thickness, height, probe rod diameter and matching piezoelectric crystal, it is processed by an advanced CNC lathe. , To ensure the technical parameters such as the coaxiality and smoothness of the processing, and to cooperate with special processing, so as to overcome the common problem of the inherent self-oscillation frequency of the vortex flowmeter on the signal.
â‘¡The sensor of the intelligent vortex flowmeter is very versatile, so that the sensor has good interchangeability. The surface of the sensor and the vortex generator are processed by advanced numerical control equipment to ensure the processing accuracy, so that the parts (especially the vortex (Generator) is versatile, so that it will not affect the repeatability and accuracy of the sensor due to the replacement of parts; it can generate a strong and stable vortex signal.
â‘¢Simple and firm structure, no moving parts, high reliability, easy to use and maintain.
â‘£The detection element is not in contact with the medium, the performance is stable, and the service life is long. The sensor is installed separately from the vortex generator and the high temperature resistant piezoelectric crystal is sealed in the detection probe, and does not contact the measured medium, so the vortex flowmeter It has the characteristics of simple structure, good versatility and high stability.
⑤ Output pulse signal or analog signal proportional to flow rate, no zero drift, high precision, easy to connect with computer
â‘¥Wide measurement range, range ratio up to 1:10
⑦The vortex flowmeter does not need to compensate when measuring the volume flow. The signal output by the vortex 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 and multiply it by the volume flow to obtain the mass flow. If the volume flow of the measured gas does not need to be compensated.
⑧ Small pressure loss. Use the DN50 vortex flowmeter to measure the flow of combustible gas. If the maximum flow in the pipeline Qmax = 200m3 / h, the pressure loss of the sensor is: â–³ P = 1.08 × 10-6 Ïv2 (kPa) = 0.605 KPa
⑨ Within a certain Reynolds number range, the flow characteristics are not affected by fluid pressure, temperature, viscosity, density, composition, but only related to the shape and size of the vortex generator.
â‘©Wide range of application, steam, gas, liquid flow can be measured.
b: Purpose:
This flowmeter can be widely used in large, medium and small pipes for water supply and drainage, industrial circulation, sewage treatment, oil and chemical reagents, compressed air, saturated and superheated steam, natural gas and various media flow measurement.
