Description
Technical field
The utility model relates to level gauging field, particularly relates to a kind of liquid level gauge measuring liquid level in clear vial.Be applicable to the measurement of liquid level in clear vial.
Background technology
Liquid level gauge is a class sensor the most frequently used in sensor, is mainly used in the degree of depth measuring various liquid level, for modern intelligent management provides the most basic sensing basis.Can the liquid level gauge of the glass of continuous coverage for a long time (or quartz) cucurbit liquid level but but do not deposit in the market.
In traditional liquid level measurement amount glass (or quartz) cucurbit, corrosivity liquid level has a several difficult problem: 1, corrosive liquids is to liquid level gauge; 2, liquid level gauge volume is excessive cannot be installed in glass (or quartz) cucurbit; 3, glass (or quartz) cucurbit volume is too small and irregular for needing to use float the liquid level gauge of float linearly to move up and down, and float is too small cannot be floated to adopt guide pole to cause; .
The utility model adopts the liquid level in laser ranging system measurement glass (or quartz) cucurbit, this device is arranged on the side of glass (or quartz) cucurbit, contact with glass (or quartz) cucurbit to limit liquid level gauge because of the characteristic of liquid in glass (or quartzy) cucurbit or bottle and use.
Utility model content
The present invention seeks to the problems referred to above existed for prior art, propose a kind of liquid level gauge measuring liquid level in clear vial.Solve the measurement for water level in the less clear vial of volume.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions:
A kind of liquid level gauge measuring liquid level in clear vial, comprising laser ranging system, also comprise the base and reflector that are arranged on clear vial both sides, base being provided with screw mandrel and the stepper motor for driving screw mandrel to rotate, screw mandrel is arranged with slide block, and laser ranging system is arranged on slide block.
Base as above is also provided with the guide pole parallel with screw mandrel, and guide pole is through the pilot hole be arranged on slide block.
Measure a liquid level gauge for liquid level in clear vial, also comprise the signal be connected with laser ranging system and stepper motor respectively and occur and processor.
The utility model compared with prior art, has the following advantages:
Non-contact measurement breaches glass (or quartz) cucurbit and characteristics of liquids to the restriction of liquid level gauge, also can not produce interference to liquid simultaneously, fill up existing market defect when level gauging.
Accompanying drawing explanation
Fig. 1 of the present utility modelly faces structural representation.
In figure: 1-signal occurs and processor; 2-signal wire; 3-guide pole; 4-stepper motor; 5-screw mandrel; 6-laser ranging system; 7-slide block; 8-base; 9-clear vial; 10-reflector.
Embodiment
Also by reference to the accompanying drawings the technical solution of the utility model is described in further detail below by embodiment.
Embodiment 1
A kind of liquid level gauge measuring liquid level in clear vial, comprise laser ranging system 6, also comprise the base 8 and reflector 10 that are arranged on clear vial both sides, base 8 is provided with screw mandrel 5 and the stepper motor 4 for driving screw mandrel 5 to rotate, screw mandrel 5 is arranged with slide block 7, laser ranging system 6 is arranged on slide block 7.Base 8 is also provided with the guide pole 3 parallel with screw mandrel 5, guide pole 3 is through the pilot hole be arranged on slide block 7.Also comprise the signal be connected with laser ranging system 6 and stepper motor 4 respectively to occur and processor 1.
Base 8 and reflector 10 are fixed on clear vial 9(vial/quartzy bottle/cucurbit) both sides and with clear vial 9(vial/quartzy bottle/cucurbit) on an axis.During liquid level gauge work, occurred to send current signal Driving Stepping Motor 4 with processor 1 by signal, stepper motor 4 controls slide block 7 by rotary screw rod 5 and moves up and down along guide pole 3.The distance of laser ranging system 6 to reflecting surface measured by laser ranging system 6 simultaneously, when clear vial 9(vial/quartzy bottle/cucurbit) in liquid-transparent time, the distance that now laser ranging system 6 measures is (be wherein liquid refractivity, for now clear vial 9(vial/quartzy bottle/cucurbit) thickness, for laser ranging system 6 is to the distance of reflector 10), laser ranging system 6 records distance and is when above slide block slides to liquid level, so when slide block 7 laser ranging system 6 when liquid/air interphase (liquid level point) records the abrupt change that distance has, when laser ranging system 6 captures this abrupt change during signal, signal occurs to stop with processor 1 control step motor 4, and calculated step motor 4 step number, the height of liquid level is calculated according to the step number of stepper motor 4.When liquid level is opaque article, laser ranging system 6 captures abrupt change signal at liquid/air interphase thus calculates liquid level.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
