AI Technical Summary
Existing flow meters are difficult to measure small flow, and the internal gear cannot rotate at low flow velocity, resulting in metering failure.
The rocking plate structure is adopted, and a light rocking plate is used instead of gears. When the fluid pushes the rocking plate, the circuit hall captures the signal to achieve small flow metering.
Effective metering of small flow rates is realized, and the metering capability of the flowmeter at low flow rates is enhanced.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of flow meters, in particular to a rocking plate type flow meter. Background Art
[0002] The working principle of a flowmeter is that liquid passing through the flowmeter drives the internal gears to rotate. Two magnets on the gears intermittently generate magnetic signals, which are captured by the Hall effect circuit and then reflected as a light feedback signal. Traditional flowmeters have a pair of meshing gears that rotate when fluid passes through them. However, if the flow rate is very low, the flow rate cannot move the gears, and the flowmeter cannot measure the flow.
[0003] Therefore, a rocking plate flow meter for measuring small flow rates is needed. Utility Model Content
[0004] In order to solve the above problems, the utility model provides a rocking plate flow meter for measuring micro flow.
[0005] A rocking plate flowmeter in the utility model includes a shell, a cover, a circuit cover, a rocking plate shaft, a rocking plate, a circuit Hall and a luminous feedback signal. The shell is provided with a cover, the cover is provided with a circuit cover, the upper center of the shell is provided with a rocking plate shaft, the rocking plate is provided in the rocking plate shaft, the circuit Hall is provided in the cover, the circuit cover is provided with a luminous feedback signal, the luminous feedback signal is connected to the circuit Hall, and the circuit Hall and the rocking plate are provided correspondingly.
[0006] In the above solution, an O-ring is further provided between the shell and the cover to seal the shell and the cover.
[0007] In the above solution, the shell and the cover are fastened by a first screw.
[0008] The above solution further includes a second screw, which fixes the circuit cover to the lid.
[0009] The advantages and beneficial effects of this utility model are as follows: This utility model provides a rocker-type flowmeter for measuring micro-flows. The internal gear is replaced by a light and thin rocker. When the rocker is naturally flat, it covers the inlet. When fluid enters the inlet, it pushes the rocker open. The Hall effect circuit captures the rocker movement signal, thus measuring even micro-flows. BRIEF DESCRIPTION OF THE DRAWINGS
