Speaking of ultrasonic flow sensors, the first thing that comes into your mind is probably the high-precision flow meter for industrial pipes or the smart ultrasonic water meter which is replacing the mechanical water meter in an increasing number of households. Though rarely associated with home appliances, ultrasonic sensors have shown their strength in making your home smarter.
Leaks from pipes, plumbing fixtures and fittings not only causes water waste, but also results 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 problem can be solved by Audiowell’s FU000X Ultrasonic Flow Sensor Module. This module 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. The flow data is calculated by the integrated TDC circuit and output in digital format. When working with an electronic valve and an mobile app, it can send you leak alerts remotely and shuts off your water immediately even when you are thousand miles away from your home.
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 sensor and electronic control system to accurately adjust the water flow. Therefore a flow sensor with high accuracy and digital output is useful in bringing good user experience.
Tankless Water Heater
Every tankless water heater needs temperature sensor and flow sensor/switch to determine how much power it should use to bring the water to the target temperature. Reed switches and hall effect sensors are often used in these water heaters. But in order to adjust the temperature more effectively, a flow sensor with high accuracy in both high and low flow range is required. FU000X has 2%-5% accuracy in the range of 15-2500 L/h and small pressure drop, which makes it a good fit to this application. Another advantage of this ultrasonic module is that it does not contain any moving part, which means higher reliability and longer work life than traditional flow sensors.
