NEW - All Gauges now come white as standard. The hydrophobic paint decreases the chance of snow build-up leading to "capping" of the inlet.
Options:
- 600 mm (24 in) capacity container
- 1000 mm (40 in) capacity container
- 1500 mm (60 in) capacity container
or
(In critical situations there is no substitute for redundancy)

DESIGN
The T-200B Series Precipitation Gauges are designed for year
round measurements of accumulated precipitation (solid or
liquid) as well as precipitation intensity. The amount of precipitation is measured
by GEONOR’s unique vibrating-wire weighing transducer.
Despite its simplicity, the
gauge is very accurate and easy to install and maintain.
The gauge was designed
to function in remote areas without heating; with proper power
supply from batteries and solar panels electrical inlet heaters
can be used to minimize "capping" of
inlet.
The T-200B Series Precipitation Gauges were developed in 1985. Some of the gauges
supplied at that time are still in use and continuously monitoring for
various meteorological agencies. They are used worldwide by
weather services, transportation agencies, power companies,
avalanche prediction services and agricultural agencies. In
comparison tests with other gauges, National Center for Atmospheric
Research (NCAR) the Climate Reference Network (CRN) and the
World Meteorological Organization/Commission for Instrument
& Methods of Observation (WMO/CIMO) ranked the T-200 first. |

MEASURING PRINCIPLE
There are no moving parts. The precipitation, oil and antifreeze
in the container are weighed with a sensor giving a frequency
output. The frequency will be a function of the tension applied
to the vibrating wire. Simply put, the frequency increases
as tension on the wire increases due to increased precipitation collected. The measuring principle
is well suited for remote locations requiring reliable and
long-lasting instruments.
The amount of precipitation can be measured at interval from
seconds to weekly. This will be determined by the programming
of the Data Logger in use.
Geonor supplies interface card for most programmable data
loggers. |
