KF800 series matallic rotameter is one of Variable-area flowmeter with simple structure,work reliable,wide application field,
high precision,convenient installing.it is suitable for compatible liquids.gases.
KF800DX eries matallic rotameter with LCD and 4-20mA electricity signal output、restrict alarm and many kinds of signal.Compared
with other flowmeters,this series has the characteristics of high-pressureproof, high-temperature proof, safety,ocular reading etc.
It is suitable for chemical industry,petroleum,matallurgy,power plant,environmental protection,medical science.
Principle structure
As the fluid upward in the tube,the float moves upward to a certain positon where the lifting force and the gravitational force
are balanced,at the moment,the circulation area between the float and the orifice is kept fixed.the circulation area is
proportinal to the height of the float, it means the height of the float represent the volumetric flowrate.When the float
moves up and down,it transmits its positional to the indicator outside in form of magnetic-coupling,so make the needle of the
indicator follows the movement of the float,and by using the cam board to show the value of flowrate linearly on the indicator
