Product Description

STS-prepaid-water-meter

The meter supports the STS prepaid protocol. Tokens can be issued to the STS meter through the CIU, infrared unit, or meter keyboard to realize prepaid recharge, switch valve, and other functions. At the same time, the concentrator supports LORA wireless automatic communication between the meters during meter readings. Networking function, the network level can reach up to level 3, which greatly improves the receiving sensitivity.

The water meter has the characteristics of accurate billing, convenient use, and efficient management.

alarm function

Battery voltage alarm: The low-voltage alarm function is triggered when the voltage is lower than 3V.
Magnetic attack alarm: When the water meter senses that the magnetic induction intensity has affected the collection and measurement, a magnetic attack alarm is triggered.
Anti-disassembly alarm: Adopts magnetic alarm function. When disassembly is encountered, changes in the magnetic field are detected and the alarm function is triggered.
Insufficient balance alarm: When the water consumption is greater than the set balance, the alarm function is triggered offline.
Overdraft amount alarm: The alarm function is triggered when the water consumption is greater than the set overdraft amount.
Flow alarm: Automatically send an alarm when continuous water consumption exceeds 24 hours; alarm when the maximum daily usage exceeds the set usage; alarm when there is continuous reverse flow.
