Lake Water Level Monitoring

The Challenge

The Brihanmumbai Municipal Corporation (BMC) required accurate, time-stamped water level monitoring for Powai Lake in Mumbai. Their existing setup had no remote visibility, no automated alerting, and no integration with the city's FTP-based data infrastructure — field staff had to physically read gauges and manually log data.

The Solution

YuDash deployed the LYNX48 data logger connected to a VEGAPULS WL61 non-contact radar sensor. The LYNX reads the 4–20 mA analog signal, applies configurable data scaling to convert the current value into water level in meters, logs it locally with a timestamp, and pushes CSV files to BMC's FTP server every 15 minutes over a 4G/LTE M2M SIM. Local storage and automatic backfill ensure no data loss during network outages.

How It Works

Data flow from field to cloud

Results

• Eliminated daily manual gauge readings by field staff
• Automated FTP delivery with zero data loss on network failure
• Scalable to additional lake monitoring points with the same config
