Background

The float flowmeter is a volume flow meter which is also called as a rotor flowmeter and measures by changing the flow area between a float and a vertical conical pipe as the float rises and falls along with the change of the flow.

The flow detecting element of float flowmeter consists of one vertical conic pipe expanding from bottom to top and one float set moving up and down along the axis of the conic pipe. When the measured fluid passes through the annular gap formed by the taper pipe and the floater from bottom to top, differential pressure is generated at the upper end and the lower end of the floater to form the rising force of the floater, when the rising force borne by the floater is larger than the weight of the floater immersed in the fluid, the floater rises, the area of the annular gap is increased, the flow rate of the fluid at the annular gap is immediately reduced, the differential pressure at the upper end and the lower end of the floater is reduced, the rising force acting on the floater is reduced, and the floater is stabilized at a certain height until the rising force is equal to the weight of the floater immersed in. The height of the float in the taper pipe corresponds to the flow passing through.
