Abstract
The utility model discloses an ultrasonic wave liquid level detection device, including installation pole setting (1), installation horizon bar (2) and ultrasonic sensor (3), to install horizon bar (2) one end and install pole setting (1) top and be connected, installation horizon bar (2) the other end is connected with ultrasonic sensor (3), still include calibrating stem (4), the one end and the installation pole setting (1) of calibrating stem (4) are connected, and calibrating stem (4) are located ultrasonic sensor (3) below. Through increasing the calibrating stem, and during calibrating stem and liquid level be in same air circumstance, the time change volume was directly proportional, through measured distance to the calibrating stem and the truly comparison of distance, can calculate a coefficient, in the function that has reached accurate measurement liquid level position, transmission with this coefficient on duty of the actual measurement the liquid level.
Description
Technical field
The utility model relates to a kind of pick-up unit, is specifically related to a kind of ultrasonic solution level detecting apparatus.
Background technology
Level gauging much adopts ultrasonic sensor to measure, current sensing station is mostly directly installed on the top of vertical fluid level, because its essence is the time turning back to sensor after the ultrasound wave sent by survey sensor reaches the water surface again, then by calculating this time, calculate the position of liquid level range sensor again, realize the measurement of liquid level.Because the aerial velocity of propagation of sound wave is very large by quality of the air influence, so cause the inaccurate of measurement result.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of ultrasonic solution level detecting apparatus, and measure accurately, little by quality of the air influence, structure is simple.
To achieve these goals, the technical solution adopted in the utility model is: a kind of ultrasonic solution level detecting apparatus, comprise and vertical rod, installation horizon bar and ultrasonic sensor are installed, horizon bar one end is installed and is connected with above installation vertical rod, the horizon bar other end is installed and is connected with ultrasonic sensor; Also comprise calibrating stem, one end of calibrating stem is connected with installation vertical rod, and calibrating stem is positioned at below ultrasonic sensor.
Described installation horizon bar is right angle with installing vertical rod angle.
Described calibrating stem is positioned at the same side of installing vertical rod with installation horizon bar, and both are parallel.
The beneficial effects of the utility model are: by increasing calibrating stem, and calibrating stem and liquid level are in same air ambient, time variation amount is directly proportional, by to the measured distance of calibrating stem and the comparison of actual distance, a coefficient can be calculated, the actual measured value of liquid level is being multiplied by the function that this coefficient reaches Measurement accuracy liquid level position, transmission.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, vertical rod is installed, 2, horizon bar is installed, 3, ultrasonic sensor, 4, calibrating stem, 5, liquid level.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, this ultrasonic solution level detecting apparatus, comprise and vertical rod 1, installation horizon bar 2 and ultrasonic sensor 3 are installed, total support that vertical rod 1 is installed for equipment is installed, horizon bar 2 one end is installed be connected with above installation vertical rod 1, install horizon bar 2 other end to be connected with ultrasonic sensor 3, installing horizon bar 2 with installing vertical rod 1 angle is right angle, can ensure that ultrasonic sensor 3 is perpendicular to tested liquid level 5; Also comprise calibrating stem 4, one end of calibrating stem 4 is connected with installation vertical rod 1, and calibrating stem 4 is positioned at below ultrasonic sensor 3, and calibrating stem 4 is positioned at the same side of installing vertical rod 1 with installation horizon bar 2, and both are parallel, the distance of calibrating stem 4 is the standard comparing point of fixed range.
Principle of work is: when the upper-lower position of liquid level 5 changes, the close echo time that ultrasonic sensor 3 detects can change, when air quality changes, what ultrasonic sensor 3 detected get to calibrating stem 4 all can be different from the time in pure air with the liquid level 5 close echo time, and calibrating stem 4 and liquid level 5 are in same air ambient, time variation amount is directly proportional, by to the measured distance of calibrating stem 4 and the comparison of actual distance, calculate a coefficient, reach Measurement accuracy liquid level position the actual measured value of liquid level 5 is multiplied by this coefficient, the function of transmission.
Claims (3)
1. a ultrasonic solution level detecting apparatus, comprise and vertical rod (1), installation horizon bar (2) and ultrasonic sensor (3) are installed, horizon bar (2) one end is installed be connected with installation vertical rod (1) top, horizon bar (2) other end is installed and is connected with ultrasonic sensor (3);
