Build Your Automatic Weather Station

The Aquamet 3500 is a fully integrated, easy-to-use computer based weather station for monitoring and reporting all the weather conditions you need to watch, including:

  • Wind Speed
  • Wind Direction
  • Air Temperature (with sun shield)
  • Barometric Pressure
  • Humidity
  • Solar Radiation
  • Precipitation

Starting with the Aqualog 3100 Data Collection Platform (DCP), which is a durable, powerful data logging and recording unit enclosed in a sturdy weather-proof NEMA 4X case, the Aquamet 3500 offers state-of-the art technology for continuous logging, storing, retrieving and integral LCD display of weather information. The standard Aqualog 3100 using the CR-10X analog input has 12 channels (0-5 VDC or 4-20 ma output) and 2 counter channels.

Weather data can be easily accessed either through a real-time report or through a log of historical data. You can also collect and save the highs, lows and averages. With the built-in clock and calendar you have continuous automatic time/date information and all the data you collect can easily be transferred to a disk file for future analysis and storage, and imported into any standard spreadsheet program.


The Aquamet 3500 with Aqualog 3100 DCP is easily programmed with the menu driven software. Program features include downloading time and date to the logger, specifying which channels to record; warm-up time; and recording interval. In addition, max, min and average can be recorded, and sensors can also be set up to read in any engineering unit. Advanced features include: setting the "zero" and "span" for each sensor and providing curve fitting for linearizing sensors or for calculating flow automatically from depth data. True exponential datalogging is also provided.


The Aquamet 3500 software provides you with a powerful tool for communicating with the logger, using a friendly menu driven/multiple choice format. You can download set up parameters, including site number and name. You can also observe all sensors in real-time, in engineering units on the Monitor mode. In addition, you can collect stored data and produce tabular and graphical reports, and you can transfer files to all common spreadsheets and databases, including Lotus 1-2-3, Excel or Dbase. This software is easy to learn and easy to use. A complete manual is provided.

Telemetry Option

The Aquamet 3500 is fully compatible with telemetry for collecting data remotely via telephone, cellular telephone, VHF/VMF radio for alert stations or GOES satellite.
