Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of ultrasonic water meter especially, one kind is ultrasonic water meter. BACKGROUND

[0002] Ultrasonic water meter is a kind of instrument using ultrasonic technology to measure water flow. Unlike traditional mechanical water meter, it detects the speed and flow of water flow by emitting and receiving ultrasonic signals, with the following main features: ultrasonic emission: ultrasonic sensor in water meter emits ultrasonic pulse; Signal reception: these pulses propagate in water flow, affected by water flow speed, received by another sensor after water flow; Flow rate calculation: by comparing the time difference between emission and reception, the speed of water flow is calculated, and then the water flow is calculated. In water flow measurement, ultrasonic water meter is often affected by impurities and bubbles in water, resulting in measurement error.

[0003] Solid impurities in water can cause attenuation and scattering of ultrasonic signals. Since the propagation speed of ultrasonic wave is affected by medium density, the presence of impurities may cause distortion of the signal received by the sensor, and thus affect the measurement accuracy. In addition, impurities in water flow may form local vortex, making the water flow speed uneven, thus causing inaccurate flow calculation. The presence of bubbles can also interfere with the propagation of ultrasonic waves. The density difference between gas and liquid formed by bubbles in water causes reflection and refraction of ultrasonic signals during propagation. Therefore, it is of great practical significance and application value to design a water meter that can better cope with this challenge and improve its measurement stability under complex water quality conditions.
