Overview

Turbine flow sensors have the characteristics of high accuracy, good repeatability, long lifespan, and simple operation. It can be widely used in industries such as petroleum, chemical, metallurgy, and papermaking to measure the instantaneous flow rate and total volume of liquids. The new generation turbine flowmeter, which has absorbed advanced technology from domestic and foreign flow meters and optimized design, 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 closed pipelines and does not corrode stainless steel, corundum, hard alloys, and has no impurities such as fibers and particles. It operates at working temperature

Product Details

LWGY seriesturbine flow meterIt is a new generation of flow meters that has absorbed advanced technologies from both domestic and foreign sources, optimized and designed with features such as simple structure, lightweight, high accuracy, good reproducibility, sensitive response, and easy installation, maintenance, and useturbine 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.This product includes various forms such as pulse output, current signal output, and internal lithium battery power supply to meet the diverse needs of users. The instrument is inexpensive, highly integrated, and compact in size. The product is also suitable for use with secondary display devices, PLCs, DCS, and other computer control systems.

turbine flow meterProduct Features:

1. High precision, generally up to ± 1% R, ± 0.5% R, and high-precision models up to ± 0.2% R;

2. Good repeatability, short-term repeatability can reach 0.05%~0.2%. It is precisely because of its good repeatability that it can achieve * accuracy through regular calibration or online calibration that flow meters are preferred for trade settlement;

3. Output pulse frequency signal and 4-20mA current signal, suitable for total measurement and computer connection, no zero drift, strong anti-interference ability;4. Can obtain high frequency signals (3-4kHz) with strong signal resolution;

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

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

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

8. 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;

9. 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.
