It generally consists of two parts: sensors and displays, or can be made as a whole. The LWGY turbine flowmeter, along with the volumetric flowmeter and the Coriolis mass flow meter, are known as the three types of flow meters with the best repeatability and accuracy. As one of the top ten types of flow meters, its products have developed into a large-scale production of multiple varieties and series.
