Product Overview
Turbine flowmeter (hereinafter referred to as TUF) is the main type of impeller flowmeter, which also includes anemometer, water meter, etc. TUF consists of sensors and conversion displays. The sensors use a multi blade rotor to sense the average flow velocity of the fluid, thereby deriving the flow rate or total amount. The rotational speed (or number of revolutions) of the rotor can be detected by mechanical, magnetic induction, or photoelectric means and displayed and transmitted by a reading device for recording. It is said that the United States had released a TUF as early as 1886, and in 1914, it was believed that the traffic of TUF was related to its frequency. The TUF in the United States was developed in 1938 for measuring the flow of fuel on airplanes. However, it was not until after World War II that a high-precision and fast response flowmeter was urgently needed for jet engines and liquid jet fuels, which allowed it to achieve true industrial applications. Nowadays, it has been widely used in various departments such as petroleum, chemical, scientific research, national defense, and metrology.
TUF, volumetric flowmeter, and Coriolis mass flowmeter are three types of products with repeatability and accuracy in flow meters. TUF has its own characteristics, such as simple structure, few processed parts, light weight, easy maintenance, high flow capacity, and adaptability to high parameters, which are difficult to achieve compared to the other two types of flow meters. The LWGY 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 for liquids with a kinematic viscosity greater than 5 × 10-6m2/s. 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: 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, suitable for total measurement and connection with computers, no zero drift, strong resistance;
4. It 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.
