Description

Technical Field

[0001] The utility model relates to the technical field of intelligent water meters, in particular to an ultrasonic water meter with a water quality monitoring function. Background Art

[0002] Ultrasonic water meter is a new type of water meter that detects the time difference caused by the change in speed when the ultrasonic sound beam propagates downstream and upstream in water, analyzes and processes the water flow rate, and further calculates the water flow rate.

[0003] The ultrasonic water meter in the prior art is usually a pipe segment type, that is, the two transducers for sending and receiving ultrasonic sound beams are both arranged on the inner wall of the pipe segment to be measured to measure the flow of the corresponding pipe segment. Among them, the propagation path of the two transducers in the ultrasonic water meter for sending and receiving ultrasonic sound beams is the measurement path.

[0004] At the same time, in order to ensure water safety, domestic water should be monitored regularly to ensure that the water supply is suitable for drinking. However, water quality monitoring is generally carried out by qualified units or personnel. For the majority of users, they cannot grasp the water quality in the first time. In addition, current water quality monitoring generally requires personnel to directly sample and test the water, which requires a lot of manpower. Moreover, after entering the pipeline, the water will be contaminated for various reasons. This secondary pollution is something that general source water quality monitoring cannot do.

[0005] The prior art attempts to configure the ultrasonic water meter with a water quality monitoring function, and the technical solution is to install a water quality sensor on the main pipe of the water meter. The water quality sensor is used to monitor the water quality of the sampling box, so that water quality data that is closer to the user's water can be collected. The main water quality items tested are pH, residual chlorine, and turbidity. However, high-velocity water flow will have a certain impact on the accuracy of the detection, and the impact on the sensor will cause damage to the sensor. If the water quality can be tested under a relatively stable condition while the water is used, the accuracy of water quality monitoring will be improved. Utility Model Content
