Quotation for selling turbine flow meters

Overview

LW400 seriesturbine flow meterIt has absorbed domestic and foreign flow meter technology and optimized its design, featuring simple structure, lightweight, high accuracy, good repeatability, sensitive response, and easy installation, maintenance, and use. new generationturbine flow meterWidely 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 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.

feature

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%~0.2%. It is precisely because of its good repeatability that flow meters are preferred in trade settlement;

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

◆ Can obtain high frequency signals (3~4kHz) with strong signal resolution;

Wide range, 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, the instrument body does not need to be perforated, 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, such as low-temperature, bidirectional, downhole, sand mixing, etc;

◆ It can measure liquids and gases, and can be inserted for large diameters.
