Gill MetConnect THP Professional Weather Station

Overview

The Gill MetConnect THP Professional Weather Station is a modular, field-deployable environmental monitoring system engineered for high-reliability meteorological data acquisition in demanding operational environments. Built upon Gill’s proven sensor architecture and robust 316 stainless steel mechanical design, the MetConnect THP implements a distributed sensing paradigm—integrating core atmospheric parameters (wind speed and direction, ambient temperature, relative humidity, and barometric pressure) within a single compact enclosure rated to IP66/IP67. Its measurement methodology adheres to WMO guidelines for surface meteorology, with sensors calibrated traceably to national standards (UKAS-accredited calibration available). Unlike monolithic weather stations, the MetConnect THP supports sensor modularity: users may extend functionality via optional inputs—including tipping-bucket rain gauge, platinum resistance thermometer (PRT), and two configurable analog channels—for analog voltage or current signals (0–5 V, 0–10 V, 4–20 mA). All measurements are time-synchronized using internal real-time clock (RTC) with ±1 second/day accuracy and output as a single ASCII string—enabling deterministic parsing and minimizing integration overhead in SCADA, PLC, or data logger ecosystems.

Key Features

• Integrated high-stability sensors: ultrasonic wind sensor (no moving parts, 0.01 m/s resolution), capacitive humidity sensor (±2 %RH typical accuracy), thermistor-based temperature probe (±0.2 °C), and piezoresistive barometer (±0.1 hPa)
• Modular expansion capability: dedicated terminals for rain gauge pulse input, PRT (PT100/PT1000), and two isolated analog inputs supporting industry-standard signal ranges
• Multi-protocol serial communication: native support for RS-232, RS-485, SDI-12, Modbus RTU, and NMEA 0183—ensuring interoperability with legacy and modern data acquisition systems
• Ruggedized mechanical construction: fully welded 316 stainless steel housing with silicone-sealed cable glands; tested to withstand continuous exposure to salt spray, UV radiation, and thermal cycling (-40 °C to +70 °C operating range)
• Diagnostic data integrity: each output string includes embedded status flags indicating sensor health, power stability, and measurement validity—critical for unattended remote deployments
• Field-serviceable architecture: all primary sensors are mechanically and electrically decoupled, allowing replacement without recalibration or system downtime

Sample Compatibility & Compliance

The MetConnect THP is designed for long-term deployment across maritime, industrial, agricultural, and renewable energy infrastructure. It complies with IEC 60529 (IP66/IP67 ingress protection), EN 61000-6-2 (immunity to electromagnetic interference), and EN 61000-6-4 (emission limits). Sensor performance aligns with WMO Guide to Instruments and Observing Methods (WMO-No. 8) recommendations for Class II automatic weather stations. While not certified under FDA 21 CFR Part 11 or ISO 17025 by default, its deterministic ASCII output format, timestamped records, and diagnostic status codes support audit-ready data logging when integrated with compliant data acquisition platforms. The system meets requirements for GLP-aligned environmental monitoring where metadata traceability and sensor fault detection are essential.

Software & Data Management

Gill provides the free MetConnect Configuration & Data Viewer software—a Windows-based utility enabling full parameter configuration (baud rate, protocol selection, sampling interval, alarm thresholds), real-time telemetry visualization, and local data export to CSV or TXT. The software logs all configuration changes with timestamps and user identifiers, supporting basic change control documentation. Raw output strings are structured per Gill’s documented ASCII protocol (e.g., “$WIND,0012.3,187,TEMP,23.4,HUM,64.2,BARO,1013.5,*4A”), facilitating straightforward parsing in Python, LabVIEW, or custom firmware. For enterprise integration, Gill supplies protocol specification documents and sample code libraries (C, Python) to accelerate development of middleware interfaces compliant with MQTT, OPC UA, or RESTful APIs.

Applications

• Maritime operations: real-time wind and pressure monitoring on port cranes, navigation buoys, and commercial vessels—supporting dynamic load calculations and safety-critical decision-making
• Distributed solar farm management: correlating irradiance (via external pyranometer input), wind speed, and ambient temperature to model PV panel efficiency degradation and predict maintenance windows
• Agricultural microclimate research: long-term collection of rainfall, humidity, and temperature gradients across field plots—compatible with FAO-56 evapotranspiration modeling frameworks
• Offshore wind turbine site assessment: deployment on temporary met masts where sensor separation minimizes flow distortion and enables directional wind shear analysis
• Environmental compliance monitoring: integration into EPA-regulated air quality networks where barometric pressure correction is required for particulate matter (PM2.5/PM10) mass concentration reporting

FAQ

Can the MetConnect THP operate independently without external power?
Yes—it supports 9–30 VDC wide-range input and features low-power sleep modes (<10 mA quiescent current), making it compatible with solar-charged battery systems for multi-year unattended operation.
Is calibration certificate included with purchase?
A factory calibration report (traceable to UKAS-accredited standards) is supplied with each unit. Full recalibration services—including on-site verification—are available through Gill’s global service network.
How is time synchronization maintained during extended power outages?
The onboard RTC retains time for up to 72 hours on backup capacitor power; upon re-energization, it resumes synchronization without data loss or timestamp drift.
Are firmware updates supported remotely?
Firmware upgrades require physical USB-to-serial connection using the configuration software; over-the-air (OTA) update capability is not implemented due to security and reliability constraints in industrial telemetry environments.
What mounting options are available for marine applications?
Gill offers dedicated 316 SS mast clamps, rail mounts, and buoy-compatible vibration-dampened brackets—all tested to ABS and DNV-GL marine environmental standards.
