Products Description
LUGB vortex flowmeters are widely used to measure the flow of liquids or gases in industrial pipelines in petroleum, chemical, electric power, light industry and other sectors. Since the sensor material is 1Cr18Ni9Ti, it can also be used for flow measurement in urban water supply, heat supply, boiler water supply, and fluid piping in the medical industry.
Features
Accurate measurement of the flow rate of gases, liquids and vapours over a wide flow range, independent of the physical properties of the fluid;
It is not affected by temperature and pressure, and at the same time, it is not easy to block, not easy to get stuck, not easy to scale, high temperature resistance, high pressure;
Safe and explosion-proof, suitable for harsh environments;
No moving parts, no holes and gaps design, the product is wear-free, dirt-resistant, no mechanical maintenance, and has a long service life;
The on-site display flowmeter with micro-power consumption and high-tech battery power supply can run for more than two years without interruption;
Integrated design of temperature and pressure compensation;
The current output is galvanically isolated, with good common-mode interference rejection ability;
The traffic value and the cumulative flow value are displayed at the same time, so there is no need to switch in turns;
The anti-vibration probe is used to effectively eliminate the influence of external vibration;
The circuit adopts surface mount process, compact structure and high reliability;
Split signal converter, cable up to 10 meters;
Wide turndown ratio up to 20:1;
The overall structure design of the instrument is reasonable, the dynamic measurement range is wide, and the pressure loss is small;
The body is made of stainless steel, which can be used for the measurement of corrosive media
