Product Details

Product Description:

QX-LWGY seriesThreaded connection type liquid turbine flowmeterIt is a new generation of turbine flowmeter that has absorbed advanced technology from domestic and foreign flow meters and has been optimized for design. It has the characteristics of simple structure, lightweight, high accuracy, good reproducibility, sensitive response, and easy installation, maintenance, and use. It is widely used for measuring liquids in closed pipelines that do not corrode stainless steel 1Cr18Ni9Ti, 2Cr13, corundum Al2O3, and hard alloys, and have no impurities such as fibers or particles. The liquid with a kinematic viscosity of less than 5 × 10-6m?/s at working temperature can be calibrated for liquids with a kinematic viscosity greater than 5 × 10-6m?/s 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.

Product Features:

High precision, generally up to ± 1% R and ± 0.5% R
Good repeatability, short-term repeatability can reach 0.05% to 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 trade settlement;
Output pulse frequency signal, suitable for total measurement and computer connection, no zero drift, strong anti-interference ability;
High frequency signals (3-4 kHz) can be obtained, with strong signal resolution;
Range measurement, with a medium to large caliber of up to 1:20 and a small caliber of 1:10;
Compact and lightweight structure, easy installation and maintenance, and high circulation capacity;
Suitable for high voltage measurement, there is no need to open holes on the instrument body, making it easy to make high voltage instruments;
There are various types of specialized sensors that can be designed according to the specific needs of users.
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.
