WINDS — WEATHER INTELLIGENCE SYSTEM

Continuous Environmental Monitoring. Zero Compromise on Reliability.

WINDS (Weather Intelligence and Networked Data Systems) stations are engineered for unattended operation in real-world conditions — delivering accurate, real-time weather data across agricultural, urban, and industrial environments.

WINDS stations measure 10+ environmental parameters — temperature, humidity, wind speed, rainfall, soil moisture, and more — in real time. Solar-powered and designed for remote operation, they transmit data via GPRS, Wi-Fi, or LoRa.

10+ Weather Parameters Solar-Powered GPRS / Wi-Fi / LoRa Real-Time Data

SENSOR CALIBRATION DOCUMENTATION

IMD Laboratory Test Reports

Review the India Meteorological Department (IMD), Surface Instruments Division, Pune laboratory reports for the tipping bucket rain gauge and ultrasonic anemometer. Both reports identify the make and calibration customer as Gujranwala Projects.

REPORT NO. 8330 · 11 AUGUST 2026

Tipping Bucket Rain Gauge

Model: GPTBRG-V0726
Resolution: 0.2 mm/tilt
Collector diameter: 159.5 mm
Collector area: 200 cm²

Observed rainfall measurement errors range from −3.3% to +1.6% across the four tested intensities, from 57.7 to 176.5 mm/hr.

The report lists IMD reference tolerances of ±4% at 50–100 mm/hr and ±5% above 100 mm/hr. These are intensity-specific tolerances.

Calibration validity stated in the report: one year.

REPORT NO. 8331 · 12 AUGUST 2026

Ultrasonic Anemometer

Model: GPUA-V0726
Calibrated speed range: 0–52.0 m/s
Direction test speed: 10 m/s
Direction tolerance: Within ±2° in the reported test

The wind-tunnel report records eight speed calibration points, with corrections from −0.1 to −0.7 m/s. Consult the PDF for the correction at each test point.

North, east, south and west indicate 000°, 090°, 180° and 270°, respectively. The report states that wind direction is within the acceptable ±2° tolerance.

Calibration validity stated in the report: one year.
