Abstract
A kind of frequency modulation radar body place instrument, it is made up of signal processor (1), display part (2), communication interface (3), mask segments (4), steel flange (5) and stainless steel antenna (6), display part (2) is arranged on signal processor (1) interior forward end, communication interface (3) is arranged on signal processor (1) one side, mask segments (4) is arranged on signal processor (1) lower end, steel flange (5) is arranged on mask segments (4) lower end, and stainless steel antenna (6) is arranged on steel flange (5) lower end.It is simple in structure, the precision height, and good stability is not afraid of stirring, bubble, high temperature, steam etc. in the use, and its range is bigger, adapts to various storage containers or process metering environment.Be specially adapted to oil field accumulating, roping, can be applicable to liquid, slurry, solid, degree of accuracy can reach ± 0.5mm.
Description
Technical field:
The present invention relates to a kind of material level gauge, especially frequency modulation radar body place instrument.
Background technology:
The height that level gauging is often referred to material in closed in the industrial processes or the open container (solid or liquid level) detects; If height of materials is carried out continuous detection, be called continuous coverage.If only whether height of materials being arrived a certain position detects and is called spacing measurement.The instrument of finishing this measuring task is called material level gauge.Level measurement instrument is used for monitoring liquid or solid material level, comprises slurry and granular solids.Its measuring principle adopts static state or dynamic measurement method, for example ultrasound wave principle, capacitance principle, radar wave principle or differential pressure principle. can be used for various processes application such as feedwater/wastewater treatment industry.
Present material level gauge is float-type, capacitance object position instrument, radio frequency admittance formula material level gauge, ultrasonic level instrument, magnetostriction material level gauge and radar material level gauge.The first five plants metering system all has separately shortcoming, existing radar material level gauge to be divided into two kinds of guided wave and pulses, and precision and stability are good inadequately, and range is limited.
Summary of the invention:
The purpose of this invention is to provide a kind of frequency modulation radar body place instrument, it is simple in structure, the precision height, good stability is not afraid of stirring, bubble, high temperature, steam etc. in the use, be applicable to abominable relatively work condition environment, its range is bigger, adapts to various storage containers or crosses gift of money for a friend going on a journey amount environment, is specially adapted to oil field accumulating, roping, can be applicable to liquid, slurry, solid, degree of accuracy can reach ± 0.5mm.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it is made up of signal processor 1, display part 2, communication interface 3, mask segments 4, steel flange 5 and stainless steel antenna 6, display part 2 is arranged on signal processor 1 interior forward end, communication interface 3 is arranged on signal processor 1 one sides, mask segments 4 is arranged on signal processor 1 lower end, steel flange 5 is arranged on mask segments 4 lower ends, and stainless steel antenna 6 is arranged on steel flange 5 lower ends.
The present invention is installed in all kinds of storage tanks top and is jar diameter 1/6 place from tank skin, and minor increment is 200mm; Can not be installed in the top or the center of feeding mouth, if be installed in central authorities, can produce multiple spurious echo, interference echo can cause dropout; If can not keep the distance of instrument and tank skin, the medium on the tank skin can stick and causes spurious echo, should carry out the spurious echo storage in the debugging instrument.
The extremely short microwave pulse that signal processor 1 emitted energy was very low when the present invention used is by 6 emissions of stainless steel antenna and reception, and radar wave moves with the light velocity, and can be converted into thing position signal working time by electronic unit.Even under the situation of operating mode more complicated, have spurious echo, also can analyze the echo of thing position accurately with up-to-date microprocessing and debugging software.
The present invention is simple in structure, the precision height, good stability, be not afraid of stirring, bubble, high temperature, steam etc. in the use, be applicable to abominable relatively work condition environment, its range is bigger, is applicable to contactless continuous coverage is carried out in the thing position of liquid, slurry and particulate material, is applicable to that temperature, pressure change greatly; The occasion that has inert gas and volatilization to exist.Adopt the measuring method of microwave pulse, and can be in the industrial frequency wavelength band operate as normal, beam energy is lower, can be installed in various metals, nonmetallic vessel or the pipeline, and human body and environment are not all had injury.Be specially adapted to oil field accumulating, roping, can be applicable to liquid, slurry, solid, degree of accuracy can reach ± 0.5mm.
Description of drawings:
Fig. 1 is a structural representation of the present invention, and Fig. 2 is the structural representation of embodiment two, and Fig. 3 is the structural representation of embodiment three.
Embodiment:
Embodiment one: with reference to Fig. 1, this embodiment is by the following technical solutions: it is made up of signal processor 1, display part 2, communication interface 3, mask segments 4, steel flange 5 and stainless steel antenna 6, display part 2 is arranged on signal processor 1 interior forward end, communication interface 3 is arranged on signal processor 1 one sides, mask segments 4 is arranged on signal processor 1 lower end, steel flange 5 is arranged on mask segments 4 lower ends, and stainless steel antenna 6 is arranged on steel flange 5 lower ends.
This embodiment is applicable to that storage or the corrosive liquid of process vessel, slurry, solid measures.
Embodiment two: with reference to Fig. 1, this embodiment is with the difference of embodiment one: described stainless steel antenna 6 is for tubaeform; Other composition is identical with embodiment one with annexation.
This embodiment is applicable to various storage containers or crosses gift of money for a friend going on a journey amount environment, liquid, slurry, solid.
Embodiment three: with reference to Fig. 3, the difference of this embodiment and embodiment two is: evenly be provided with heat radiator 7 between mask segments 4 and the steel flange 5; Other composition is identical with embodiment two with annexation.
This embodiment is applicable to the hot environment measurement.
