Abstract
A float flow meter with LED light pillar display is composed of a float, a permanent magnet, a taper pipe, a plurality of Hall elements, a plurality of LED lamps and a control circuit. The float is arranged in the taper pipe, and when fluid flows through the taper pipe, the float can move in the axial direction of the taper pipe under the action of fluid acting force; the permanent magnet is arranged on the float; the Hall elements are arranged in the axial direction of the taper pipe and electrically connected with the control circuit, the control circuit is electrically connected with the LED lamps which correspond to the Hall elements one to one, and when a certain Hall element induces the magnetic field of the permanent magnet, the corresponding LED lamp emits light. The float flow meter has the advantages that visuality of flow display of the float flow meter is improved, a user can read flow values conveniently at night under the no-lighting and remote conditions, the display part is free of mechanical transmission components, and therefore the float flow meter is stable and reliable in work and light in weight.
Description
Technical field
The present invention relates to a kind of suspended body flowmeter, relate in particular to a kind of suspended body flowmeter showing with LED light beam.
Background technology
Suspended body flowmeter is the usual means in fluid measurement field, and its measuring principle is: the uninterrupted of indirectly knowing the fluid from flowing through in Taper Pipe by measuring the displacement of float under fluid force effect, improvement of the present invention for problem be: existing suspended body flowmeter generally adopts pointer indicating device to show uninterrupted, flow number can only represent with the scale circumferentially distributing, its intuitive is poor, simultaneously, owing to being limited to the volume size of pointer indicating device, when distant, numerical value on the very difficult accurately reading pointer type indicating device of operating personnel, in addition, in pointer-type indicating device, there is a large amount of physical construction, structural stability is poor, and the physical construction in pointer indicating device need to be protected by metal shell, cause installation weight larger.
Summary of the invention
For the problem in background technology, the present invention proposes a kind of suspended body flowmeter showing with LED light beam, its structure is: described suspended body flowmeter is made up of float, permanent magnet, Taper Pipe, multiple Hall element, multiple LED lamp and control circuit; Described float is placed in Taper Pipe, and in the time having fluid to flow through in Taper Pipe, float can be along Taper Pipe axially-movable under the acting force effect of fluid; Described permanent magnet is arranged on float; Described multiple Hall element axially arranges along Taper Pipe, multiple Hall elements and control circuit electrical connection, control circuit and the electrical connection of multiple LED lamp, multiple Hall elements are corresponding one by one with multiple LED lamps, in the time that a certain Hall element senses the magnetic field of permanent magnet, corresponding LED lamp is luminous.
The luminous electrical principle of measuring principle of the present invention and driving LED lamp is all same as the prior art; Principle of work of the present invention is: in the time of fluctuations in discharge, float position changes under the acting force effect of fluid, thereby the magnetic field of permanent magnet is detected by different Hall elements, when detecting behind the magnetic field of permanent magnet, be subject to the triggering of the induction electromotive force of Hall element generation, control circuit will drive corresponding LED lamp luminous; Adopt after the present invention; operating personnel can be very intuitively just judge current flow number luminous by which exhibition LED lamp of identification; and still can clearly be identified at night and when more remote; in device, there is not mechanical transmissioning piece; stability is better; can save the metal shell for the protection of mechanical transmissioning piece in prior art, installation weight is alleviated.
Preferably, the setting area of described multiple Hall elements is positioned at float distance of run scope.
In order to improve the degree of integration of device, the present invention has also done following improvement: described multiple LED lamps are stitched together and form an integrally-built LED light beam by one dimension arrangement mode.
In order further to improve the intuitive of device in the time showing flow, the present invention has also done following improvement: putting in order of described multiple LED lamps is identical with putting in order of corresponding Hall element.
In order further to improve the degree of integration of device, the invention allows for following preferred version: described Hall element, control circuit and LED lamp are encapsulated in same housing, and described housing is fixed on Taper Pipe surface.
In order to improve the aesthetics of device, the present invention has also done following improvement: the length of described LED light beam and the stroke range of float are isometric, and the stroke range equal altitudes of LED light beam and float arranges.
For the ease of flow is measured, the present invention has also adopted following preferred version: described multiple Hall element spaced sets.
Preferably, described permanent magnet adopts magnet steel.
For fear of permanent magnet, by flow-induced corrosion, the present invention has also done following improvement: in described permanent magnet is wrapped in by float.
Useful technique effect of the present invention is: improves intuitive when suspended body flowmeter shows flow, has been convenient to night without the flow number read operation under lighting condition and under remote condition, and display section machinery-free driving member, working stability is reliable, and weight is lighter.
