MetConnect Weather Stations

The Gill Instruments MetConnect series represents a major shift in professional weather monitoring, serving as a highly flexible hardware platform that bridges the gap between compact weather stations and complex, custom environmental networks. Built upon heavy-duty 316 Stainless Steel architecture, MetConnect acts as a centralised master telemetry hub. It houses high-precision base sensors for Temperature, Humidity, and Pressure while providing integrated M12 sensor port connections. This allows operators to wire in external sensors (such as tipping rain buckets, water quality probes, solar pyranometers, or specialised anemometers) and seamlessly combine all inputs into a single, time-synchronised digital data string.

Core Features & Technical Breakdown

  • The Multi-Sensor Hub Concept: Equipped with three dedicated input channels via industrial M12 8-way connectors. The internal processor gathers signals from external third-party hardware, provides them with localised 5V power, applies time-stamps, and integrates their readings into a single digital data output stream.
  • WMO Compliant Micro-Climate Design: Engineered to satisfy strict World Meteorological Organisation (WMO) siting criteria. Standard all-in-one stations force all sensors to sit at the exact same physical position. MetConnect’s modular inputs allow you to keep the master array at a standard 1.5-meter height for true thermodynamic profiling, while running a remote cable to place your anemometer at the WMO-recommended 10-meter height.
  • Reference-Grade Core Accuracy: The integrated solid-state sensors deliver exceptional measurement accuracy: Air Temperature is tracked to ±0.2°C (across -35°C to +70°C), Barometric Pressure within ±0.5 hPa, and Relative Humidity within ±1.5%.
  • Extensive Flexible Input Matrix: The auxiliary M12 ports support a broad range of data types out of the box, including dual analogue channels (0-5V or 4-20mA loop lines), a dedicated 4-wire PT100 temperature probe input, and a high-speed digital pulse contact closure channel.
  • Industrial Communication Layer: Consolidates all base parameters and auxiliary sensor metrics down a single data loop. It natively supports RS232, RS422, RS485, Modbus RTU/ASCII, SDI-12 v1.3, and standard marine NMEA 0183 output options.

Because professional monitoring arrays are built to match specific structural layout challenges, the MetConnect suite is offered in two core physical models. If you require a complete, immediate deployment that handles wind tracking right out of the box, the MetConnect One features an integrated, high-durability ultrasonic anemometer head fixed directly to the frame. If your site plan calls for a remote anemometer positioned on a separate tower mast, or if your parameters omit wind vectors entirely, the MetConnect THP provides the exact same robust stainless steel hub box and base sensor array without the integrated wind head.

MetConnect One

MetConnect One

The MetConnect One delivers complete, reference-grade environmental tracking from a single mast footprint. It permanently integrates an open-path ultrasonic wind sensor with a heavily shielded temperature, humidity, and barometric pressure grid. Perfect for rapid deployment where spatial constraints or structural design prohibit multiple mounting towers, it combines all core parameters into one synchronised digital data string right out of the box.

MetConnect THP

MetConnect THP

World Meteorological Organisation (WMO) regulations mandate measuring wind vectors at 10 meters to clear ground friction, while temperature, humidity, and pressure must sit between 1.25 and 2 meters. The MetConnect THP natively satisfies this separation requirement, capturing reference-grade thermodynamic profiles at ground level while seamlessly aggregating cabled data from a remote mast-mounted anemometer into a single synchronised string.
