Description
Technical Field
The utility model relates to the technical field of flowmeters, in particular to a metal tube float flowmeter.
Background
The metal tube float flowmeter (also known as metal rotor flowmeter) has the characteristics of simple structure, reliable work, wide application range, higher precision, convenient installation and the like. The method can be suitable for flow measurement of opaque media and corrosive media. Metal tube float flow meters are variable area flow meters, i.e., in the vertical measurement tube of the flow meter, as fluid flows up the tube. The float moves upwards, the lift force borne by the float at a certain position is balanced with the gravity of the float, and the area of a circulation annular gap between the float and the orifice plate (or the taper pipe) is kept constant. The annulus area is proportional to the rise height of the float, i.e. a certain height of the float represents the magnitude of the flow. The metal tube float flowmeter is widely applied to petroleum, chemical industry, power generation, pharmacy, food, water treatment and the like. The flow measurement process is complicated, under severe environmental conditions, and under various medium conditions.
The metal tube float flowmeter in the prior art has the following defects when in use: the use is inconvenient, and the float is continuously abraded and corroded due to the impact of the liquid, so that the service life of the float is short.
