Flow Detection
Features:
1. At a supply voltage of 3.6V, the current consumption is 1uA. At 1.7V, the current consumption is only 300nA, which is the lowest Hall power consumption on the market.
2. ESD ability exceeds ±5500V, ensuring reliability.
Flow Detection
There are 2 Hall ICs placed in the water meter. The pulse output from the ICs are used to detect the flow rate and the direction of the water flow, that achieving the following two functions:
1. Water flow count
2. Anti-stealing water detection
