AI Technical Summary
Existing electromagnetic water meters or flow meters consume a lot of power when performing high-precision measurements, which is difficult to meet the needs of battery-powered applications. In addition, they require a large excitation current in low-flow scenarios, resulting in energy redundancy. In high-flow scenarios, they continue to work even when a high excitation current is not required, which increases battery wear and makes it impossible to dynamically balance accuracy and battery wear.
An ultrasonic sensing unit monitors the water flow and an electromagnetic control module determines the water flow status, which is divided into three states: measurable flow, critical flow, and ineffective flow. The excitation current is controlled by a timer and a multi-level constant current source module. By combining and optimizing ultrasonic and electromagnetic measurement data, the excitation current and electromagnetic start/stop can be dynamically adjusted.
When high-precision measurement is required, the electromagnetic water meter or flow meter is activated, and it remains in sleep mode when not needed to reduce battery consumption. The optimal excitation current is selected according to the flow rate to achieve a dynamic balance between energy consumption and accuracy, thus extending battery life.
