1.Product Introduction

The LWGY series turbine flow meter is based on the principle of torque balance and belongs to the velocity-type flow meter. The flow meter has the characteristics of simple structure, light weight, high precision, good reproducibility, sensitive response, convenient installation, maintenance and use, etc. It is widely used in industries such as petroleum, chemical engineering, metallurgy, water supply and papermaking, and is an ideal instrument for flow measurement and energy conservation.  

​​2.Main Features

1)Simple and compact structure, light weight, easy installation and maintenance. 2)High accuracy, the measurement accuracy of liquid turbine flow meter can generally reach ±1%R, ±0.5%R 3)Multiple outputs can be optional, 4-20mA, RS485, Hart. 4)Low power consumption，long life and easy to operate. 5)High-definition backlight LCD display. 6)Professional explosion-proof enclosure. 7) Suitable for high-pressure measurement, no holes are required on the instrument body.

 6.Installation

<1> At all times, the pipe must be completely filled with liquid. Otherwise the flow display will be affected, resulting in measurement errors. <2> Straight pipe requirements <3> Avoid bubbles If bubble enter the measuring tube, the flow display may be affected, resulting in measurement errors.
