This utility model addresses the issue that most traditional water flow monitoring is based on pipelines, which requires installation in pressurized closed pipes and cannot measure open channels such as natural rivers and artificial water conveyance channels. By using ultrasonic detection, non-contact measurement is achieved, which can monitor and record water flow in real time, improve the accuracy and reliability of water flow measurement, and is suitable for various industrial and environmental monitoring scenarios. Example
[0020] like Figure 1 and Figure 2As shown, the technical solution in this application embodiment effectively solves the technical problems of traditional mechanical flow meters, which, although accurate, suffer from easy wear, high maintenance costs, and high requirements for fluid cleanliness. The overall idea is as follows: A water flow monitoring device based on ultrasonic technology includes an upstream channel 3, a Parshall metering tank 4, and a downstream channel 5. The Parshall metering tank 4 is a Parshall metering tank with a throat width of 0.051m, installed between the upstream channel 3 and the downstream channel 5. A sensor bracket 2 is installed above the water inlet of the Parshall metering tank 4, and an ultrasonic sensor 1 is installed in the middle of the sensor bracket 2. The ultrasonic sensor 1 is a WL-1A1 type ultrasonic sensor, which includes an ultrasonic sensor probe 101 and a calibration rod 102. An instrument 6 is connected to the ultrasonic sensor 1, and the ultrasonic sensor 1 and the instrument 6 transmit signals through an RS485 terminal. The instrument 6 displays water flow monitoring data in real time. A power supply 7 is installed on the instrument 6, which is a 220V AC power supply. The instrument 6 is used to process the data of the signals collected by the ultrasonic sensor 1.
[0021] To address the problems existing in the prior art, this utility model provides a water flow monitoring device based on ultrasonic technology. This utility model addresses the issues that most traditional water flow monitoring is based on pipelines, which requires installation in pressurized closed pipes and cannot measure open channels such as natural rivers and artificial water conveyance channels. By adopting ultrasonic detection, this utility model achieves non-contact measurement, which can monitor and record water flow in real time, improve the accuracy and reliability of water flow measurement, and is suitable for various industrial and environmental monitoring scenarios.
[0022] Working principle:
[0023] First, power is supplied to instrument 6 via power supply 7, and the water flow monitoring device begins to work. Ultrasonic sensor 1 is fixedly installed in the middle of sensor bracket 2 and aligned with the water surface. Ultrasonic sensor probe 101 emits ultrasonic waves towards the water surface. After time t1, the ultrasonic waves travel a distance E1 and encounter calibration rod 102. Part of the ultrasonic energy is reflected by calibration rod 102 and received by the probe. Instrument 6 records the length of this time t1. Another part of the ultrasonic energy bypasses calibration rod 102 and reaches the water surface after time t2. This part of the energy is reflected by the water surface and received by ultrasonic sensor probe 101. Instrument 6 records the length of this time t2. The length E1 of calibration rod 102 does not change. Based on the received signal, instrument 6 can calculate the distance from the water surface to ultrasonic sensor probe 101, D=E1*t2 / t1, thus obtaining the liquid level information. Since Parshall metering tank 4 is a Parshall metering tank with a throat width of 0.051m, water flow information can be obtained.
[0024] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
