Description
Technical field
The present invention relates to checkout equipment field, be specifically related to a kind of turbo flow meter.
Background technology
Flowmeter is the instrument measuring fluid flow, along with industrial expansion, to the accuracy of flow measurement and area requirement more and more higher, in order to adapt to multiple use, various types of flowmeter is come out one after another, and is widely used in the industries such as petroleum gas, petrochemical complex, water treatment, food and drink, pharmacy, the energy, metallurgy, paper pulp papermaking and building materials.The accuracy of existing flowmeter survey is not high, and structure is not compact, and especially easily by extraneous power supply disturbance, cost is higher.
Summary of the invention
The present invention, in order to overcome the deficiency of above-mentioned technical matters, provides a kind of turbo flow meter, can solve above-mentioned technical matters completely.
The technical scheme solved the problems of the technologies described above is as follows:
A kind of turbo flow meter, comprise turbine, air deflector, magneto converter, shell and signal amplification circuit, described turbine is connected with air deflector and supports by air deflector, described turbine upper end is connected with magneto converter, air deflector described in described shell surrounds and turbine, described shell is provided with the web member be connected with detected fluid pipeline, and described magneto converter is positioned at the outside of shell, and described signal amplification circuit is connected with magneto converter.
Described turbine is made by the stainless steel of high magnetic permeability.
Described turbine inside is provided with impeller, and described bead core is provided with spiral vane, and fluid matasomatism makes it to rotate in blade.
Described air deflector and turbine junction are provided with supporting member, be used for stabilized fluid the flow direction and supporting impeller.
Described shell is that non-magnet material is formulated, and in order to fix and to protect inner each parts, and is connected with fluid line.
Described magneto converter is made up of coil and magnet steel, during wheel rotation, makes coil induces pulse electrical signal.
Signal amplification circuit is used to amplify the feeble signal exported by magneto converter.
Turbine meter is based on conservation of angular momentum principle, and fluid impact turbo blade, makes turbine rotate, and the rotational speed of turbine changes with the change of flow, can convert the rotation of turbine to electric pulse by the magneto converter outside turbine.
The accuracy of measurement of turbo flow meter is higher, can reach more than 0.5 grade, be swift in response, and can survey pulsating flow, form linear relationship between flow and secondary speed, small-bore flow detection in being mainly used in.
Accompanying drawing explanation
