LWYC series turbine flowmeterbrief introduction

The LWYC series turbine flowmeter is a new generation of turbine flowmeter that has been optimized and designed based on advanced technology of flow meters at home and abroad. It has the characteristics of simple structure, lightweight, high accuracy, good reproducibility, sensitive response, and easy installation, maintenance, and use. It is widely used to measure 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 × 10-6m2/s at working temperature can be used after real liquid calibration of the flowmeter. 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, ± 0.5% R, and high-precision models up to ± 0.2% 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;

specializedsensorThere are many types, which can be designed as various specialized sensors according to the special needs of users, such as low-temperature, bidirectional, downhole, sand mixing, etc
