Detailed Product Description
product description of flow meter
KF800 series metallic 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 series metallic 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,metallurgy,power plant,environmental protection,medical science.
principle structure
As the fluid flow upward in the tube,the float moves upward to a certain position where the lifting force and the gravitational force are balanced,at the moment,the circulation are between the float and the orifice is kept fixed.the circulation area is proportional 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.
