Met One- 30.5 Industrial Grade Sonic Anemometer

A rugged, industrial-grade sonic anemometer designed for accurate wind speed and direction measurement with no moving parts, making it highly reliable and virtually maintenance-free.

  • High-Accuracy Wind Measurement: Wind speed up to 60 m/s with ±0.5 m/s or 5% accuracy and ±5° wind direction accuracy.
  • No Moving Parts: Maintenance-free design ensures long-term reliability in harsh environments.
  • Flexible Outputs: Supports RS-232, RS-485, and analog (0–1 VDC) for easy system integration.
  • Rugged & Field-Ready: Wide temperature range (-40 to +60°C) with automatic north alignment compass for fast deployment.

Description

The Met One 30.5 Industrial Grade Sonic Anemometer is a rugged, high-performance sensor designed for accurate wind speed and wind direction measurement in demanding industrial and environmental applications. Using sonic measurement technology with no moving parts, it delivers reliable wind data across a wide operating range up to 60 m/s (134 mph) with excellent resolution and low starting threshold. High-accuracy digital and analogue outputs ensure precise real-time monitoring, while the built-in alignment compass provides automatic north alignment for fast and accurate deployment.

Built for long-term field use, the 30.5 Sonic Anemometer operates in extreme conditions from −40 °C to +60 °C and up to 100% relative humidity, requiring virtually no maintenance. Its robust construction, flexible power input, and multiple signal output options (RS-232, RS-485, and analogue) make it easy to integrate into existing monitoring systems. With its combination of durability, portability, and dependable performance, it is ideal for industrial sites, meteorological networks, and environmental monitoring projects where reliability is critical.

Features

  • Nothing Moves.
  • There is no periodic upkeep.
  • Outputs, both digital and analogue.
  • North Alignment automatically.
  • Flexible in the field.
  • Ruggedness, portability, and high reliability.
