Product Details

LWGY Explosion proof Liquid Turbine Flow Sensor/Transmitter

I. Overview

LWGYThe series of turbine flow sensors are a new generation of turbine flow meters that have been optimized and designed based on domestic and foreign flow instrument technology. They have the characteristics of simple structure, lightweight, high accuracy, good reproducibility, sensitive response, and easy installation, maintenance, and use. They are widely used for measuring stainless steel in closed pipelines1Cr18Ni9TiThe2Cr13And corundumAl2O3Hard alloy does not corrode and has no impurities such as fibers or particles. Its kinematic viscosity at working temperature is less than5×10-6m2/sLiquid with a viscosity greater than5×10-6m2/sThe liquid can be used for 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.

This type of turbine flow product itself does not have on-site display function, and only transmits the flow signal in the form of pulses for remote output. The instrument is inexpensive, highly integrated, and compact in size, making it particularly suitable for use with secondary display devicesPLCTheDCSWaiting for the computer control system to be used in conjunction.

2、 Product Features

1. Accuracy, generally up to ±1%R, ±0.5%RThe high-precision type can reach ±0.2%R

2. Good repeatability, short-term repeatability can be achieved0.05%~0.2%,It is precisely because of its good repeatability, such as the accuracy obtained through regular calibration or online calibration, that flow meters are preferred in trade settlement;

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

4. Can obtain high frequency signals(3-4kHz)Strong signal resolution;

5. Wide range, capable of reaching medium to large diameters1:20The small caliber is1:10

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.
