- Model WM III Ten Meter - Basic Weather Systems

From

WM III Ten Meter Basic Weather System includes: Battery-operated 10-meter system with data logger or universal interface module (UIM). Operates on AC or DC power. Data logger or UIM card provides the power and interface for the sensors. Data can be recorded remotely, on site with the logger or to a local PC with the UIM and WeatherView software. System can operate from batteries for up to one week or indefinitely with the solar panel/rechargeable battery option, or from commercial AC power.

The weather is monitored for many reasons as it can have a major impact our lives and our work. For example, real-time information about ambient atmospheric conditions provides the necessary input data required to make the proper decisions during an industrial emergency involving any type of hazardous material. Depending on the plant type, size and age, the federal Environmental Protection Agency (EPA), as well as municipal and state environmental regulatory organizations, also requires that a number of basic meteorological variables are continuously measured and recorded on site to ensure compliance with environmental regulations. Other applications include transportation safety, energy conservation and development, wind power systems, food and forest production, climatological studies, health effects research, and for forecasting severe storms.

Climatronics’ Basic Weather Stations are designed to provide users with an easy way to assemble an integrated weather monitoring system that meets all of their needs and will collect all the weather data they need. The system uses reliable and accurate sensors to measure the weather variables of interest. The sensors are connected to a data logger which is housed in a weatherproof enclosure. The data logger supplies excitation signals to the sensors and converts the sensor output signals to digital data, which are RS-232C or RS-422/485 compatible and available in printable or comma delimited ASCII or optionally with MODBUS protocol. The data logger will also store the data and, if required, perform computational preprocessing such as averages, standard deviations, max/min, as well as certain control functions.

When isolated 4-20 mA current loop signals are required and/or when on-site data storage is not required, the Universal Interface Module (UIM) is used as a lower cost alternative to the data logger. The data logger can also be provided with digital to analog converters for this function.

Climatronics has developed and is producing a sonic anemometer of novel design that can replace traditional wind sensors. We call this sensor the Sonimometer, which is a standard feature of our Basic Weather Station that provides several advantages over both mechanical and other solid-state sensors. With no moving parts, it requires no periodic maintenance, lowering the user's life-cycle costs. Our unique design means that it can tolerate a build-up of dirt, dust, snow, or other foreign matter in the sensing volume without measurement degradation. The design also improves accuracy and reliability since there are no 'arms' supporting the transducers to move, vibrate, or to provide roosts for birds. The digital output of the Sonimometer also means that there will be no conversion (A-D) or line-loss errors. For those who prefer a mechanical wind sensor, that option is also available.
