SMALL METEOROLOGICAL STATION AMS 156
AMS 156 is low-cost, compact, lightweight, computerised, low power meteorological station for ground measurements. Electronics of the station is enclosed in a cabinet that can be, together with the power supply unit, easily mounted on a standard mounting rail. IP 65 protected cabinet can be used to mount AMS 156 outside. Station can accept all standard meteorological sensors (temperature, relative humidity, atmospheric pressure, wind, ground temperature, precipitation, etc.) Other sensors (hydrological, radiological, environmental ....) can also be added. Meteorological calculations, such as evaporation, sunshine duration, QFF, QFE, QNH, dew point, automatic SYNOP generation, etc, can be incorporated in the station software. AMS 156 has internal FLASH EEPROM data memory, which can be enlarged by standard removable memory cards.
Main features of AMS 156 are:
measures flexible set of parameters, important for different meteorological studies
high accuracy
simple operation
long autonomy with the battery power supply
power supply 230V AC, possible powering from the alternative sources (wind, solar panels)
internal data storage
serial, optical or Ethernet data transfer
AMS 156 measures and calculates the following values:
instant data
average values (in pre-set intervals)
maximums (in pre-set intervals)
minimums (in pre-set intervals)
precipitation sums
evaporation ... e.t.c.
All parameters that control the functioning of the station can be set by the built-in menu system. They are stored in a non-volatile memory and used at each restart of the station.
At the end of each measuring interval, station stores the calculated data into its memory on a FIFO principle. Data are not lost if the station is powered off. Stored data can be reviewed or transmitted to the external computer. Much longer data storing intervals (up to several years) may be achieved by use of FLASH EEPROM memory cards. These cards can be removed from the station and used as portable data-transfer media.
