Accurate Water Level Monitoring for Every Application

EcoTech Engineering supplies, installs, and commissions In-Situ Digital Water Level Recorders for groundwater observation wells, rivers, canals, reservoirs, and hydrological monitoring networks. Our end-to-end solutions cover instrument supply, borehole installation, telemetry setup, and ongoing AMC — ensuring continuous, reliable data for regulatory compliance and water resource management.

Key Capabilities

Everything you need for reliable, compliant water level monitoring.

High-Accuracy Level Measurement

Submersible pressure transducers with vented or non-vented configurations for accurate water level readings in boreholes, open wells, rivers, and reservoirs.

GPRS / 4G Telemetry

Integrated or external data loggers transmit readings at configurable intervals over GPRS/4G to cloud servers and regulatory portals — no manual site visits required.

Data Logging & Storage

On-board memory stores months of readings at programmable intervals, with automatic upload on connectivity and local data retrieval via USB or Bluetooth.

CGWB / CWC / State Board Integration

Data formatted and transmitted directly to Central Ground Water Board, Central Water Commission, and State Water Board online portals for regulatory compliance.

Threshold Alerts

Configurable high/low water level alarms delivered via SMS and email for flood warning, drought monitoring, and aquifer management.

AMC & Calibration

Annual Maintenance Contracts covering scheduled site visits, sensor calibration, battery replacement, telemetry checks, and data continuity assurance.

Featured Instrument

Industry-leading In-Situ instruments trusted by CGWB and CWC monitoring programmes.
