CHAPTER 2
PRODUCT OVERVIEW
This chapter introduces the features, accessories, sensors, and the
product nomenclature.
Vaisala HydroMet™ Systems include compact stations that can be used
either with a portable tripod (MAWS201) or with pole masts of
different heights in fixed installations (MAWS101 and MAWS301).
The station comes with a set of sensors, that measure certain
meteorological and/or hydrological quantities and that have been
especially selected for use with Vaisala HydroMet™ Systems.
Vaisala HydroMet™ System MAWS301
Vaisala HydroMet™ System MAWS301 is a new generation AWS
especially designed for applications where no commercial power or
communication networks are present, or are too expensive to be
installed. Due to its flexibility and economical design, MAWS301 is
also an ideal choice for hydro meteorological and hydrological
applications. The possibility to use the same and standard equipment for
many different requirements lowers the cost of training, spare parts, and
logistic support.
MAWS301 has been designed for applications where only a few
sensors are required. However, MAWS301 can be easily upgraded,
even in the field, to include a larger set of sensors including smart
sensors such as ceilometer, visibility and present weather sensors, and
water quality probes. The same basic system with its options and
accessories can provide with all the needs of meteorological and
