1. Ultrasonic Flow Sensing Technology
Traditional mechanical water meters rely on rotating impellers that wear out over time, especially when exposed to sand particles or lime deposits. Dholera’s AMR meters use solid-state ultrasonic technology:
- No Moving Parts: Ultrasonic meters measure water velocity using transit-time acoustic waves. This design eliminates mechanical wear, preventing measurement drift and ensuring accuracy over a 10-year battery lifespan.
- Reverse Flow Detection: The meters can detect if water is flowing backward through the pipe, immediately alerting the municipal team of potential siphoning or backflow contamination.
- Tamper Protection: If a property owner attempts to open the meter casing or bypass the line, internal sensors trigger a tamper alert message to the central database.
2. AMR Telemetry & SCADA Integration
Water consumption data flows from individual plots to municipal billing servers through a multi-tier network:
- Wireless Edge Transmission: Every meter contains a low-power wireless transmitter that sends hourly consumption logs using LoRaWAN or NB-IoT protocols to local area collector gateways.
- Fiber Backhaul: Collector gateways consolidate the wireless signals and transmit the data via the underground fiber-optic network directly to the ABCD Building database.
- Motorized Shut-off Valves: Every meter assembly is equipped with an electronic motorized gate valve. In the event of a detected pipeline leak, unauthorized line usage, or unpaid billing cycles, ABCD operators can close the property’s water feed remotely within 30 seconds.
The table below details Dholera’s smart water meter specifications:
| Technical Parameter | Specification Standard | Operational Benefit |
|---|---|---|
| **Flow Measurement Tech** | Symmetrical Transit-Time Ultrasonic | Eliminates mechanical wear, registers low flow rates |
| **Communication Protocol** | LoRaWAN / NB-IoT (868 MHz / 920 MHz) | Low-power, long-range wireless data transmission |
| **Battery Lifespan** | Minimum 10 Years (Lithium Thionyl) | Zero maintenance operation for developers |
| **Control Valve Type** | Electric Motorized Ball Valve | Permits automated remote shutoff from ABCD Center |
| **Remote Valve Shutoff** | Less than 30 Seconds | Rapid leakage control and flow regulation |
| **Protection Rating** | IP68 (Waterproof & Dustproof) | Operates reliably inside flooded underground utility boxes |
3. Strategic Benefits for Industrial Plot Buyers
- Automated Leak Alerts: The SCADA system monitors baseline water flow during late-night hours. If a constant flow is detected when a factory is closed, the system sends an automated SMS alert to the owner, warning them of an internal pipe leak.
- Elimination of Manual Readings: Because all consumption data is transmitted wirelessly, there is no need for manual meter readings on-site, eliminating human transcription errors.
- Precise Pressure Management: By checking water pressure across different sectors, the DICDL water network dynamically adjusts pump speeds, reducing pipe bursts.
Frequently Asked Questions (FAQ)
#### What is an AMR water meter in Dholera?
An Automatic Meter Reading (AMR) water meter is a smart utility device that measures water usage using ultrasonic waves and transmits consumption data wirelessly to the municipal offices without requiring manual inspections.
#### Can the municipal team shut off water supply remotely?
Yes. Every smart water meter setup includes a motorized valve that can be closed remotely from the ABCD Command Center within 30 seconds to manage leaks, emergency situations, or billing issues.
#### Do these smart meters require electrical power connections?
No. Dholera’s smart water meters are powered by long-life lithium batteries designed to run continuously for 10 years without replacement, ensuring operations continue during power outages.
