While everybody is talking about technology trends like smart grids, smart cities, smart mobility or smart homes don’t forget that most of these developments are based on sensors and digital communication. As a consequence, when it comes to metering applications, any devices now using moving parts are no longer an ideal choice. Today highly reliable and precise ultrasonic sensors are first choice when replacing traditional mechanical devices in water, gas or heat meters. At Sensor+Test Audiowell Electronics (Guangdong) Co., Ltd. will present quite a few examples of their wide variety of ultrasonic sensors for metering applications, leakage detection or level control in household appliances. Tracking trends in digital transformation is providing a guideline for Audiowell’s ultrasonic product strategy.
Leaks from pipes, plumbing fixtures and fittings not only cause waste of water, but also result in property damage. While most leak sensors are installed on the floor and alerts you when it detects water or moist around, they cannot do anything when the leakage occurs in invisible spots, such as toilet flapper valves and cracked water supply lines.
Now this challenge is met by ultrasonic flow sensor modules. Audiowell’s series FS000X uses a pair of ultrasonic sensors to make real-time flow measurement. Due to its large dynamic range, any dripping as slow as 1 … 6 l/h can be detected no matter where the leak occurs. Flow data are calculated by the integrated TDC circuit providing digital format output. These flow data can be utilized by smart home systems which will send you leak alerts by mobile app while you are thousand miles away from home. Dripping and leaking can be distinguished from normal water consumption if the system has AI or a well-designed algorithm to learn the pattern of daily water use.
As a closed-loop solution, Audiowell also provides a plastic ball valve which can be connected with this flow sensor module perfectly and allows you to shut off your water immediately.
The manual switch has been abandoned by some advanced bathroom products such as smart faucet, smart shower and auto fill bathtub. Instead, they use flow sensors and electronic controlled systems to accurately adjust water flow. Therefore a flow sensor with high accuracy and digital output is useful in bringing good user experience.
Watering the lawn can be automated with the power of digitization. Most of the current systems use a timer to control the sprinkler. However, the actual water consumption in gardening can be greatly different from what you expect, especially when pipes are blocked or leaking. Ultrasonic flow sensors are a good fit in smart gardening applications. As no moving parts are used in these modules, they can maintain good performance after long-term use without being damaged by particles in the water. Audiowell’s FS000X Ultrasonic Flow Sensor Module features accuracies as high as ±2 %. It has four models with different sizes available now: DN10, DN15, DN20 and DN25.
