Glass Rotameter

Working principle

Rorameter with alarm swich bitable magnetic excitation functions using the magnetron, magnetic float to achieve contacts with the opening and closing. Relays and other componects to achieve with their own sound, light alarm needs


The flowmeter is mainly composed of a piece of taper glass pipe with bigger bottom and smaller top and a

floater moving up and down along with the fluid flow(Fig.3).When the fluid flows across the taper pipe

from bottom to top, the floater rises under the lift force "S" on the floater due to the fluid dynamic

energy and the fluid buoyancy force "A".When the sum of the lift force "S" and the buoyancy force "A" is

equal to the floater weight "G", the floater is in equilibrium and stable at a certain height. The scale on

the taper pipe indicates the fluid flow.
