Abstract
The utility model discloses an ultrasonic level gauge installs at least two and works in the ultrasonic transducer of different frequency in ultrasonic sensor. The utility model discloses an ultrasonic level gauge has improved ultrasonic level gauge's measuring range and precision, has reduced it and has measured the blind area.
Description
Technical field
This utility model relates to a kind of ultrasonic level gage, belongs to measuring appliance field.
Background technology
In industrial processes, level gauging is conventional operation, by measuring the Level Detection control that the height of liquid in containers medium can be used in automated production process, warning, data analysis and process. Along with the development of the progress of technology and computer technology, current level gauging has been realized in automatically detecting intellectuality, and data process rapid, thus improve production efficiency.
At present, fields of measurement has developed multiple different level measurement scheme, owing to ultrasonic reflections detection realizes level gauging according to ultrasound wave from being transmitted into the principle receiving the interval size relation proportional to measured medium height launching echo in all multi-schemes, fixed point can be realized and continuous print is measured, and various measurement environment are all had well adapting to property by it, it is applied widely at industrial circle, becomes the level gauging mode being favourably welcome.
The probe that the operation principle of ultrasonic level gage is sensor launches ultrasound wave, and sound wave is received by same sensor after body surface reflects, and converts the signal of telecommunication to; Transmitter calculates the sensor distance to testee according to the time between transmitting and the reception of sound wave. Applying ultrasonic lever meter to measure distance and blind area are relevant with the frequency of sensor,
Remote distance of measuring is suitable for the low sensor of frequency (precision is relatively low, blind area is big), and near distance of measuring is suitable for the high sensor of frequency (precision is high, blind area is little).
Existing ultrasonic level gage due in an instrument only one of which ultrasonic sensor cause that it is to precision with measure in the environment that all requires of distance and cannot apply. The such as large oil tank of height 15 meters, in order to measure its degree of depth, it is necessary to uses the ultrasonic sensor of 35KHz. But the blind area of the ultrasonic sensor of 35KHz has 0.5 meter, it is impossible to meet industrial controlling precision needs. Current common solution is to install second small-range ultrasonic level gage auxiliary in oil tank to improve precision, not only results in installation complexity, and application cost also raises.
Summary of the invention
For the deficiencies in the prior art, this application provides a kind of simple in construction, solution with low cost, by installing multiple ultrasound probe in same ultrasonic level gage, take into account the needs measuring range and precision.
Specifically, this utility model is achieved by the following technical solution:
A kind of ultrasonic level gage, is provided with at least two in ultrasonic sensor and works in the ultrasound probe of different frequency.
Improved by said structure territory and the ultrasound probe that a series of activities frequency is different can be uniformly installed in the sensor, can realize being suitable for and measure scope as far as possible widely, can guarantee that again and under the big degree of depth, obtain certainty of measurement.
Applicant extensively considers the needs in practical application, and usual ultrasound probe is two, and the two size is identical, arranged relative. This mode can meet being actually needed in most cases.
Owing to the application of many ultrasound probes is primarily to the deficiency made up in single probe precision, therefore in above-mentioned dual probe structure, one low frequency ultrasound ripple probe is used for improving available investigation depth as main probe, another ultra-high frequency ultrasonic wave probe is used for the precision ensureing to measure as auxiliary probe, the operating frequency of this ultra-high frequency ultrasonic wave probe is at least the twice of low frequency ultrasound ripple probe operating frequency, so that it is guaranteed that certainty of measurement can be effectively improved.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model ultrasonic level gage.
Detailed description of the invention
In the following example, applicant provides the more excellent realization of one of the present utility model in conjunction with accompanying drawing. In structure provided below, the quantity of ultrasound probe, operating frequency, mounting means etc. are only schematic, and this utility model does not constitute restriction especially.
With reference to Fig. 1, ultrasonic level gage of the present utility model, (due to the known features that attachment structure is all ultrasonic level gages such as transmitter, position illustrates herein to be connected to two ultrasound probes on transmitter. This utility model hinge structure is modified in that ultrasound probe part), the two ultrasound probe is positioned at the bottom of ultrasonic level gage, and its size is identical, is mounted opposite. The wherein operating frequency f of main probe 11For 35KHz, the operating frequency f of auxiliary probe 22For 90KHz.
In real world applications, in time using more ultrasound probe, according to operating frequency distribution, ultrasound probe annular spread can be arranged on bottom liquidometer.
