Core Components

Central Tank as the
Water Source

  • Water is supplied from main central water tank.
  • This acts as the starting point of distribution to households or smart city projects.

Smart Water Meter & Motor Actuator

  • The Smart AMR (Automatic Meter Reading) Water Meter measures water consumption.
  • A Motor Actuator is connected to a pipeline for ON/OFF control of water supply.
  • It also provides Open/Close position feedback to confirm status and operates on command received.

Internet & LoRaWAN Connection

  • The Water Meter communicates via LoRaWAN.
  • An internet connection ensures that data can be sent to remote servers.

LoRa-Enabled Network Server

  • Data from Smart Water Meter is transmitted to a LoRaWAN Network Server (LNS)
  • This server manages communication between the devices and higher-level systems.

Application Server (Zeminet Software)

  • The application server receives the usage data and control signals from the LNS.
  • It processes the information, manages prepaid balance, and sends ON/OFF commands.
  • Accessible via Wi-Fi or Cellular connection, ensuring flexibility.

User Interface – Zeminet Software

  • End-users and utility providers can access the system through Zeminet Software.
  • It provides dashboards for monitoring consumption, balance, and control functions.

Residential/Smart City Projects

  • The final water distribution reaches house-holds or smart city projects.
  • Consumers get water based on pre-paid credits, ensuring controlled usage and transparency.

User Transparency

Real-time usage and balance visibility.

User-Initiated Recharge

Recharge Initiation

  • User recharges using mobile app/ website/ UPI.
  • Recharge request is processed by Application Server.

Credit Update

  • Application server updates prepaid balance for the user account.
  • Command sent via Network Server – Gateway – Water Meter.

Water Consumption

  • As user consumes water, meter deducts usage from prepaid balance.
  • Meter sends consumption data periodically to server.
  • User gets balance alerts.

Exhaustion of balance

  • If balance reaches zero, meter valve automatically closes.

Feedback Mechanism

  • Operator dashboard App updates status (ON/OFF) of valve.

Operator-Controlled Command (ON/OFF)

Operator Action

Operator sends ON/OFF command from Application Server.

Data Path
