Pan Xin Machinery Co., Ltd., Wuhan production and sales of a variety of professional level gauge Phone Zhang 
 Level gauge magnetic flap structure is the use of the principle of the bypass pipe, leading tube equipment level and container level within the highly consistent foundation Archimedes theorem, magnetic float in the liquid buoyancy and gravity balance float floating on the surface, when the measured level in the container movements, the dominant tube level gauge also will lift the float, the float inside the permanent magnet driven by magnetic coupling indicator indicator within the flap, when the liquid bit up or down, the flap indicator turning from white to red, or turn from red to white, the color change indicator is the height of the actual height of the measured medium level, site level in order to achieve instructions. 
 Flap in a variety of liquid level meter for large towers, tanks, boilers and other high temperature and pressure sealed container. Safe, reliable, durable, intuitive, and the measurement range. Coupled with magnetic switch can be realized or community-bit level, the lower limit alarm and control; coupled with liquid level transmitter, liquid level signal can be converted into a continuous output signal: 40 ~ 20mA, to achieve long-range detection, instructions, records and control.
