Turbine flowmeter can measure gases and liquids, with advantages such as high sensitivity and precise measurement.

1、 Product Overview

The LWGY turbine flowmeter has been optimized and designed by drawing on advanced flow meter technologies from both domestic and international sources,The new generation turbine flowmeter with the characteristics of simple structure, lightweight, high accuracy, good reproducibility, sensitive response, and easy installation, maintenance, and use is shown in Figure 1Widely used for measuring liquids in closed pipelines that do not corrode stainless steel 1Cr18Ni9Ti, 2Cr13, corundum AI2O3, and hard alloys, and have no impurities such as fibers or particles. The liquid has a kinematic viscosity of less than 5 × 10-6m2/s at working temperature. For liquids with a kinematic viscosity greater than 5 × 10-6m2/s, the flowmeter can be calibrated for real liquid before use If paired with display instruments with special functions, it can also perform quantitative control, over limit alarm, etc., making it an ideal instrument for flow measurement and energy conservation

2. Output pulse frequency signal, suitable for total measurement and computer connection, no zero drift, strong anti-interference ability;

3. Can obtain high frequency signals (3-4kHz) with strong signal resolution;

4. Wide range, with a medium to large caliber of up to 1:20 and a small caliber of 1:10;

5. Compact and lightweight structure, easy installation and maintenance, and high circulation capacity;

6. Suitable for high voltage measurement, there is no need to open holes on the instrument body, making it easy to make high voltage instruments;

7. Can be made into an insertion type, suitable for measuring large diameters, with low pressure loss, low price, can be removed without interruption, and easy installation and maintenance.

8. Good repeatability, short-term repeatability can reach 0.05%~0.2%. It is precisely because of its good repeatability that frequent calibration or online calibration can achieve extremely high accuracy, making it a preferred flowmeter for various manufacturers
