Abstract
The invention relates to an ultrasonic liquid level sensor, in particular to a liquid level, liquid temperature and flow integrated measuring device and method based on ultrasonic echoes. The problems that an existing ultrasonic liquid level sensor is long in response time and low in measurement precision are solved. A liquid level, liquid temperature and flow integrated measuring device based on ultrasonic echoes comprises a base, a flange plate, an ultrasonic pulse transceiver, a top cover, a fastening bolt, a clamping cushion block, a piezoelectric ultrasonic transducer, a threaded plug, a side cover, a waveguide rod A, a waveguide rod B, a waveguide rod C and a waveguide rod D; a concave cavity A is formed in the center of the upper surface of the base, and a wiring hole A is formed between the side face of the concave cavity A and the left surface of the base in a penetrating mode; a blind screw hole is formed in the right part of the upper surface of the base; a boss A extends from the upper part of the right surface of the base; a concave cavity B is formed in the lower portion of the right surface of the base, and a wiring hole B is formed between the side face of the concave cavity B and the bottom face of the concave cavity A in a penetrating mode. The device is suitable for liquid level measurement of the horizontal pipeline.
Description
technical field [0001] The invention relates to an ultrasonic liquid level sensor, in particular to an integrated measuring device and method for liquid level, liquid temperature and flow based on ultrasonic echo. Background technique [0002] Ultrasonic level sensors are widely used in level measurement of horizontal pipelines. Under the existing technical conditions, the ultrasonic liquid level sensor has the problems of long response time and low measurement accuracy due to the non-contact measurement principle. Specifically, when the existing ultrasonic liquid level sensor is working, both ultrasonic pulses and ultrasonic echo pulses propagate through the gas medium, which on the one hand leads to a slow propagation speed, on the other hand, the propagation speed is easily affected by environmental factors (such as dust, mist, etc.), which on the one hand leads to a longer response time and on the other hand leads to a lower measurement accuracy. Based on this, it is n...
