Description
Technical field
The utility model belongs to measuring instrumentss technical field more particularly to a kind of external-placed type supersonic liquid level based on ARM
Measuring device.
Background technology
Currently, the measuring instrument in life is mostly contact type measurement, have very for some complicated structure planar survey
Big difficulty, but it is high in face of viscosity, degree of corrosion is strong, pollution is strong, for the medium that easily crystallizes, measure it is just relatively difficult,
Contactless gauge is many times needed with this.
In conclusion problem of the existing technology is：There is prodigious difficulty for some complicated structure planar survey,
Lack that suitable range is wide, not by the contactless gauge of medium influence.
Invention content
In view of the problems of the existing technology, the utility model provides a kind of external-placed type supersonic liquid level based on ARM
Measuring device.
The utility model is realized in this way the external-placed type supersonic liquid level measuring device includes：Shell, probe；
It is inlaid with probe in the shell side cylindrical hole；
Card has human-computer interaction interface in the front notch；
The human-computer interaction interface is connect with power supply by conducting wire；
The auto charge and discharge module, Signal acquiring and processing module, transmitting and receiving module, automatic compensating module use
Conducting wire is connected.
Further, there are red light and green light respectively in the upper right of shell and left side；
Further, there is switch in the shell lower right corner.
The advantages of the utility model and good effect are：It is light-weight with small, it is applied widely the advantages that, in work
The industries such as industry, oil, chemical industry have wide future.In the case of complicated endoporus, advantage is more obvious.To complexity
The liquid level of inner cylinder carries out automatic location, will greatly improve testing efficiency and precision, greatlys save test funds, the development to industry
Progress has prodigious facilitation.
Description of the drawings
Fig. 1 is the external-placed type supersonic liquid level measuring device structural schematic diagram that the utility model embodiment provides；
In figure：1, shell；2, human-computer interaction interface；3, power supply；4, auto charge and discharge module；5, Signal acquiring and processing mould
Block；6, transmitting and receiving module；7, automatic compensating module；8, conducting wire；9, it pops one's head in；10, red light；11, green light；12, it switchs.
Specific implementation mode
For that can further appreciate that the utility model content, feature and effect of the utility model, the following examples are hereby given, and
It is described in detail with the accompanying drawings as follows.
The structure of the utility model is explained in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, the external-placed type supersonic liquid level measuring device that the utility model embodiment provides includes：Shell 1, people
Machine interactive interface 2, power supply 3, auto charge and discharge module 4, Signal acquiring and processing module 5, transmitting and receiving module 6, automatic benefit
Repay module 7, conducting wire 8, probe 9, red light 10, green light 11, switch 12.
Probe 9 is inlaid in 1 lateral cylindrical hole of shell, card has human-computer interaction interface 2, human-computer interaction interface in the notch of front
2 are connect with power supply 3 by conducting wire 7, and auto charge and discharge module 4, Signal acquiring and processing module 5 emit with receiving module 6, certainly
Dynamic compensating module 4 is connected using conducting wire 7, has red light 10 and green light 11 respectively in the upper right of shell 1 and left side, the lower right corner has
Switch 12.
The operation principle of the utility model：
Probe 9 is placed on detection to be tested outside liquid level on linea ventralis, power supply 3 is powered to human-computer interaction interface 2, and probe 9 will be received
The signal arrived gives the processing of Signal acquiring and processing module 5, is then passed to transmitting and receiving module 6, finally by automatic compensation
The processing of module 4, the inside of 10 bright expression of detector red light at this time is gas；Green light indicates that the inside is liquid.It detects repeatedly several
Scribe line position determines the position in gas-liquid line of demarcation.Usually when not in use, the switch 12 in the lower right corner is closed.
Why can realize non-contact, be more than the human auditory system limit because ultrasonic wave refers to frequency in 20kHz or more
Sound wave, gas or liquid or solid medium.Ultrasonic permeability ability is strong, and weak very little, declines in gas in liquid, solid
It is weak quickly, when ultrasonic wave is injected from a kind of medium in another medium, will produce reflection and refraction effect in medium interface.It is super
Sound wave aerial spread speed about 340m/s, spread speed about 1500m/s in water, in metal such as in the propagation of steel speed
Spend about 5700m/s.Sound wave is from metal layer to when air layer incidence, and acoustic impedance difference is larger, and sound wave is almost entirely anti-on interface
It penetrates, projection amount is few.The aftershock duration of multiple reflections is longer in metal pipe-wall.Sound wave is incident from metal layer to liquid level
When, acoustic impedance difference is smaller, and for sound wave on interface in addition to reflection, also portion of energy penetrates into liquid, remaining in metal pipe-wall
It shakes weak very fast.
The key technical indexes：(1) measurement accuracy：± 0.11L (2) supply voltage：Direct current 24V (3) ultrasonic frequency：2MHz
(4) refresh time is detected：2.4ms (5) measures the activity duration：≤ 5 minutes (6) temperature in use environment：- 40 DEG C -50 DEG C (7) use
Humidity environment：93% (35 DEG C)
The above is only the preferred embodiment to the utility model, is not made in any form to the utility model
Limitation, it is every according to the technical essence of the utility model any simple modification made to the above embodiment, equivalent variations with
Modification, is all within the scope of the technical scheme of the utility model.
