Can also be used for scientific research in laboratories and the like. The main measuring element of the panel flowmeter is a conical tube with a downward small end and an upward large end and a floater which can move up and down in the conical tube. When fluid flows through the conical pipe from bottom to top, a pressure difference is generated between the upper part and the lower part of the floater, and the floater rises under the action of the pressure difference. When the force for raising the float is equal to the resultant force of gravity, buoyancy and viscosity, the float is in balance position. Thus, there is a proportional relationship between the fluid flow through the meter and the float rise height, i.e., the flow area of the meter, and the float position height can be used as a flow measurement.
