Bluetooth split IC card prepaid water meter

The Bluetooth split type IC card prepaid water meter consists of two parts: the meter end measurement control box and the NB Bluetooth communication box, which can form a one-to-one or one to many Bluetooth meter collection system. It is particularly suitable for application scenarios where the water meter is installed in the meter well and is not convenient for card swiping or recharging. The metering control box at the meter end completes independent metering and valve control operations. The communication control box communicates with each meter end through Bluetooth communication to form a network, and optional NB communication function is added to enable data upload
