Overview
The WeatherPak® 400 is a simple to operate, easily deployable, compact weather station measuring wind speed, wind direction, wind stability class, temperature, humidity and pressure. The data can be monitored visually on the LCD display and simultaneously output to plume modelling software on a PC.
It is a reliable, portable weather station designed to withstand harsh environments and rough handling and is constructed of non-sparking, intrinsically safe Mil-Spec grade aluminium which will even survive a 2 m drop onto concrete and is water immersible (for decontamination etc).
There are no cables to connect or exposed wires or switches and it is deployable from carry case to full operation within one minute. The system is available in several configurations including tripod or vehicle mounting. Data can be received via fixed data cable or wireless and displayed on a touch screen display and / or input to a computer.
Using the remote data transmission the user can deploy the WeatherPak® in one location and move to a safer location up to 10 km away. Several WeatherPak® units can be networked together and using the optional Global Positioning System plume models will be updated without any manual input.
Applications include military, fire services, chemical plants and oil refineries etc.
Features
- can be fully decontaminated after chemical or biological incidents
- low maintenance, fully sealed unit with no moving parts
- can be mounted on buildings, vehicles or tripod
- data can be output to a PC for plume modelling, data visualisation and archiving
- fully deployable within 60 seconds
- designed to withstand harsh environments and rough handling
Examples of data output
The data can be viewed on a display as well as being output as an ASCII data string to a PC. The data can be imported into plume modelling programs such as CAMEO® / ALOHA®, SAFER® Systems software, or to programs such as MS Excel.
The Raw Data is delivered in ASCII format in metric units (millibars, m/s, C), whereas the processed data is converted to Standard English units (inches, mph, F).
Two “checksums” are performed to ensure that the message is sent correctly. The PC adds up the “ASCII value” of the data line (each letter, number, comma etc has a numerical value universal to all computers) to make sure that the PC received the same number that the WeatherPak transmitted.
Below is an example of the standard data string together with the field line explanations (custom configurations are available) .
