Description

Metal tube float flowmeter

Technical Field

The invention relates to the technical field of instrument production, in particular to a metal tube float flowmeter.

Background

The metal tube float flowmeter adopts the variable area type measuring principle to produce and research, and is suitable for measuring liquid and gas. The float of the metal tube float flowmeter moves upwards along with the change of flow in the measuring tube, the buoyancy force applied to the float at a certain position is balanced with the gravity of the float, and the circulation annular gap area between the float and the pore plate is kept constant at the moment. The annular gap area is proportional to the rise height of the float, i.e. the position of the float rising in the measuring tube represents the magnitude of the flow, and the changing position of the float is transmitted by the internal magnet to an external indicator, which correctly indicates the value of the flow at that time. This leaves the indicator housing out of direct contact with the measurement tube.

If a measured medium such as water is in a state of unstable pipeline fixation due to too fast water flow speed, instantaneous impact or too large and too violent water flow interval, the vibration can be generated to damage an instrument and influence the measurement of a flowmeter when the water pipe vibrates or the surrounding environment vibrates greatly.
