The Vaisala HydroMet™ Automatic Weather Station MAWS201 is a portable AWS for temporary installations, featuring the same design as the Vaisala TacMet Tactical Meteorological Observation System MAWS201M for demanding tactical meteorological applications. Its lightweight aluminium tripod and easy-to-use connectors make it fast to set up. Each leg is adjustable for use on uneven terrain.
Easy to Set Up and Configure MAWS201 is easy to set up. Every sensor is supplied with a cable and connectors for easy installation. All components fit together easily and no special tools are required. Vaisala Lizard Setup Software simplifies the configuration of sensor measurements, calculations, data logging schedules, and data transmissions. There are templates to guide you through the initial setup, anda large number of further options if you want to customize the settings further.
Accurate Sensors The basic sensor suite measures wind speed and direction, atmospheric pressure, air temperature, relative humidity, and precipitation. Optional sensors can be added to measure, for example, soil/water temperature, global and net solar radiation, soil moisture, and water level. The performance of the sensors has been proven in the field in a wide range of environments.
Reliable in All Weather MAWS201 operates reliably in all weather: its corrosion-resistant, anodized aluminum construction is rugged and weatherproof. The cables are made of high-quality polyurethane with moulded, watertight connectors that fulfill the requirements of the IP68 standard. All the inputs are surge-protected.
The quality control software checks the
sensor data against the user-set
climatological limits, as well as the step
changes between successive
measurements. Each statistical
calculation has its own, userconfigurable validation routine.
Statistical Calculations The statistical calculations include
minimum, maximum, average, standard
deviation, and cumulative values. All are
calculated over user-defined intervals. All
extreme values can be timestamped.
In addition, a library of calculations is
available. These include, for example,
unit conversions, dew point, frost point,
QNH, QFF, QFE, evapotranspiration,
sunshine duration, forest fire index, wind
chill, and heat stress.
Versatile Data Outputs The user can freely configure the data
output formats. Several ready-made
templates make configuration easy.
The alarm module notifies the user when
a measured or calculated value exceeds
the set threshold values. The alarm
module can be configured, for example,
to send an alarm message, to change
timing intervals, to log data, and to set
an excitation voltage for controlling
an external device.
