Installing smart water meter for the elderly people living alone went viral!

2021-01-22 Product Information

Recently, Installing smart water meter for the elderly people living alone in Shanghai, China, jiangsu road street went viral which reported by Xinhua News Agency. If the reading of the intelligent water meter is less than 0.01 cubic meter within 12 hours, the warning information will be timely fed back to the street and neighborhood committee through the "One Network Management" platform, and the staff will visit the elderly immediately to learn about the situation of the elderly people living alone in real time.

Intelligent water meter will become a new wind of the industry

In fact, it is not only in Shanghai, but also in all parts of China that smart water meters have been gradually popularized. And We use it to get through the”last kilometer”of smart water. Smart water is one of the core construction points of smart city, and it can help cities achieve more efficient, more convenient and safer water resources management through water IoT technology.

Intelligent water meter, the mainstream tool of water metering in the future, is a new type of water meter that integrates modern micro-electronic technology, modern sensing technology and intelligent remote transmission technology, and it can measure water consumption, transmit data and clear trade transaction. Among them, ultrasonic intelligent water meter has gradually become the industry's first choice because of its high precision measurement.


The working principle of ultrasonic intelligent water meter

Ultrasonic intelligent water meter is composed of measuring pipe section, ultrasonic flow sensor, signal processing circuit, algorithm and flow display.The built-in ultrasonic flow sensor converts the electric energy into ultrasonic mechanical energy, which is transmitted to the measured water body, and then receives the reflected echo. Finally, the signal is processed by the electronic circuit and converted into the electrical signal representing the flow, which is provided to the  integrating meter for calculation and display.

In the environment of Internet of things, Ultrasonic intelligent water meter can upload data to the cloud so as to realize remote reading and processing.  At the same time, it is conducive build a new trend of intelligent water affairs.


Sensor technology of ultrasonic intelligent water meter

Ultrasonic sensor is the component of ultrasonic intelligent water meter to generate signal, and its function is to provide accurate, stable and continuous ultrasonic signal for water meter circuit.  Ultrasonic sensor transmits and receives the ultrasonic wave together with the metering pipe section and the reflection structure. The MCU accurately calculates the flow velocity and flow rate by measuring the time difference between the forward and reverse flow propagation of the ultrasonic pulse.


Audiowell ultrasonic flowmeter

As a professional solution product provider of intelligent instrument industry, Audiowell has developed an ultrasonic flowmeter integrating ultrasonic sensor and measuring pipe segment. Three specifications of DN15, DN20 and DN25 are widely used in ultrasonic intelligent water meter.
