The vortex flowmeter is a speed type flow instrument which has a wide range of uses. It is suitable for flow metering, measurement and control of liquids, steam and most gases.The vortex flowmeter adopts a new design of structure with mechanical shock resistance,impact resistance and stain resistant. It has no moving parts, no wear, and no mechanical maintenance.The vortex flowmeter has low pressure loss, stable performance, high accuracy. It’s of easy installation and use, and sensors and signal converters are interchangeable.The LUGB type vortex flowmeter is a new type of flowmeter introduced by our company, the design of which is reasonable and the function is powerful, it also has linear correction function,reaching the world advanced level. The flowmeter adopts a high-resolution low-power full dot-matrix LCD display, which is clear and intuitive and it’s easy to operate. RS485 or HART communication can meet various needs of users; 12 kinds of compensation algorithms can almost satisfy all flow compensation calculations. Correction curve relying on external data and calibration method based on standard signal lead the trend of instrument calibration.
1. No moving components, long-term stabilization, structure is simple for easy installation and maintenance 2. The output of the sensor is the pulse frequency, its frequency is linear with the actual flow rate of the fluid measured, it has no zero drift, and the performance is very stable. The structure is various in the form of pipeline and plug-in type flow sensors; 3. The accuracy is high, the accuracy of measuring liquid is usually 11.0%, and the accuracy of measuring gas is ± 1.5%; 4. The measurement range is wide, and in the range of Reynolds number is 2×10 4 ~7×10 6 , it can reach 1:20; 5. Low pressure loss(about 1 /4-1 /2 of the orifice flowmeter), which belongs to the energy-saving flow instrument; 6. The installation method is changeful. It can be installed horizontally, vertically and at different angles according to different process pipelines; 7. It adopts interference cancellation circuit and anti-vibration sensor head, so it has certain anti-environmental vibration performance; 8. It adopts ultra-low-power single-chip microcomputer technology. For one 3V10Ah battery, can be used for more than 5 years; 9. The nonlinearity of the meter coefficient is corrected by software to improve the measurement accuracy; 10. Adopts EPROM to conduct power fail safeguard to the accumulative flow, and the effective protection time is more than 10 years.
