Further, as a preferred embodiment, two ends of the cone 3 are respectively provided with a sealing ring 13.
In the first embodiment, the panel flowmeter 1 operates on the principle that when external fluid is introduced into the conical body 3 in the flowmeter 1 through the fluid joint 6 and flows through the conical hole from bottom to top, differential pressure is generated between the upper part and the lower part of the float on the conduit 4, the float rises under the action of the differential pressure, and when the rising force of the float is equal to the resultant force of the gravity, the buoyancy and the viscous force borne by the float, the float is in a balance position. The flow of the flowmeter 1 is thus proportional to the rise height of the float, i.e. to the flow area of the flowmeter 1, and the position height of the float can be used as a force flow measure.
Therefore, the flowmeter 1 can monitor the pressure change in the flow regulation process in real time, the detection accuracy is guaranteed, and meanwhile, the structure is simple, the practical requirement is lowered, and the measurement range is larger.
