Recently, Xinhua News Agency reported that Shanghai Jiangsu Road Street for the elderly living alone to install smart water meter news has become a hot spot, within 12 hours of the smart water meter readings less than 0.01 cubic metres, early warning information will be fed back to the streets and neighbourhood committees through the "one network unity management" platform in a timely manner, and the staff then visit the elderly, real-time understanding of the situation of the elderly living alone. The smart water meter will become the new wind of the industry.
Smart water meter will become the industry's new wind mouth
In fact, not only in Shanghai, the whole country has begun to gradually popularise the use of smart water meters, in order to open up the "last kilometre" of intelligent water services. Smart water is one of the core construction points of the smart city, through the water Internet of Things technology, help the city to achieve a more efficient, more convenient and safer water resources management.
The mainstream tool of future water measurement - smart water meter, is a set of modern microelectronics technology, modern sensing technology, intelligent remote transmission technology in one, can be measured on the amount of water consumption and data transmission and settlement transactions of the new water meter. Among them, ultrasonic smart water meter has gradually become the industry's first choice for its high-precision measurement advantages.
Working principle of ultrasonic smart water meter
Ultrasonic smart water meter consists of measuring pipe section, ultrasonic flow sensor, signal processing line, algorithm and flow display and other components. The built-in ultrasonic flow sensor converts electrical energy into ultrasonic mechanical energy and launches it into the measured water body, then receives the reflected echo, which is then processed by the electronic circuit for signal processing and converted into an electrical signal representing the flow rate, which is supplied to the display and accumulation instrument for calculation and display. In the environment of the Internet of Things, ultrasonic smart water meter can also upload data to the cloud to achieve remote reading and processing, and collaboratively construct a new situation of intelligent water.
Sensing technology of ultrasonic smart water meter
The ultrasonic sensor and metering pipe section are the signal generating parts of the ultrasonic smart water meter, whose role is to provide accurate, stable and continuous ultrasonic signals for the water meter line. The ultrasonic sensor cooperates with the metering pipe section and reflective structure to transmit and receive ultrasonic waves, and the MCU accurately calculates the flow rate and flow rate by measuring the time difference between the ultrasonic pulse propagating downstream and propagating against the flow.
Ultrasonic Flow Sensor
As a professional solution provider in the smart meter industry, AUDIOWELL has developed ultrasonic flow meters integrating ultrasonic sensors and metering sections, and the three specifications of DN15, DN20 and DN25 are widely used by ultrasonic smart water meters.
Audiowell has independently developed a variety of flow sensors with high consistency, no need for screening and pairing, and sells millions of pieces annually, matching with the integrated injection moulding metering pipe section, which has the features of small pressure loss, low starting flow rate, no moving parts in the pipe section, etc., and effectively improves the metering accuracy of the water meter.
Audiowell ultrasonic flow sensor is also made of drinking water grade raw materials, in line with GBT17219-1998 "Code for Health and Safety Evaluation of Drinking Water Transmission and Distribution Equipment and Protective Materials for Living Water", to meet the needs of household water use, and effectively solve the hidden problems of water safety.
