Kaidi KD QTLU Precession Vortex Flow Meter for Compressed Air, Natural Gas
The FRL series turbine flow meter is a new generation of turbine flow meters with the characteristics of simple structure, light weight, high precision, good reproducibility, sensitive response, easy installation, maintenance and use. It is widely used. It is not corrosive to stainless steel 1Cr18Ni9Ti, 2Cr13, corundum AI2O3 and cemented carbide in measuring closed pipelines, and there is no fiber, particles and other impurities. The kinematic viscosity of liquids with a kinematic viscosity of less than 5×106m2/s at working temperature is greater than 5× The liquid of 106m2/s can be used after the flow meter is calibrated in real liquid. If matched with a display instrument with special functions, it can also carry out quantitative control, over-quantity alarm, etc. It is an ideal instrument for flow measurement and energy saving.
➪ High accuracy, generally up to ±1%R, ±0.5%R, high-precision type up to ±0.2%R;
➪ Good repeatability, the short-term repeatability can reach 0.05%~0.2%. It is precisely because of the good repeatability. For example, frequent calibration or online calibration can obtain extremely high accuracy. It is the preferred flow meter in trade settlement;
➪ Output pulse frequency signal, suitable for total measurement and connection with computer, no zero drift, strong anti-interference ability;
➪ High frequency signals (3~4kHz) can be obtained, and the signal resolution is strong;
➪ Wide range, medium and large diameters can reach 1:20, and small diameters are 1:10;
➪ Compact and lightweight structure, convenient installation and maintenance, and large circulation capacity;
➪ It is suitable for high-pressure measurement, and there is no need to open holes on the meter body, so it is easy to make a high-pressure meter;
➪ There are many types of special sensors, which can be designed as various special sensors according to the special needs of users, such as low temperature type, two-way type, downhole type, special type for sand mixing, etc.;
➪ It can be made into a plug-in type, suitable for large-caliber measurement, with small pressure loss, low price, continuous flow out, easy installation and maintenance

When the measured fluid flows through the sensor, under the action of the fluid, the impeller is rotated by force, and its speed is proportional to the average flow velocity of the pipeline. The rotation of the impeller periodically changes the magnetic resistance value of the magnetoelectric converter. The magnetic flux in the detection coil changes periodically to produce a periodic induced electric potential, that is, an electric pulse signal, which is amplified by an amplifier and sent to the display instrument for display.
