How to Maintain Road Weather Stations

As winter approaches, road maintenance services teams work hard to check and prepare their equipment for the challenging conditions ahead. Typically, most of the work is calibrating sensors and swapping out single modules, but after some time in operation, the entire station needs to be renewed.

Caltrans, the California Department of Transportation, took the opportunity to choose and install devices and services from OTT HydroMet.

Caltrans is responsible for monitoring a wide range of meteorological parameters along the roads and highways of California. These include air temperature, amount and type of precipitation, pressure and relative humidity, as well as wind speed and direction.

In four of its stations, Caltrans made the decision to dispose of its outdated equipment while maintaining the main infrastructure and without interfering in data communication processes.

Customized Sensor Setup for Easy Integration

OTT HydroMet was able to retrofit the stations with sensors and accessories from its proven and trusted meteorological brand and product portfolio. As stated in World Meteorological Organization guidelines, wind and air data are measured at various heights. The configuration of each station is comprised of the following:

  • Lufft LCOM: Industrial PC with a built-in 7-inch touch screen display for communication purposes.
  • Lufft WS300: Smart Weather Sensor for temperature, air pressure and relative humidity.
  • Lufft WS200: Smart Weather Sensor for ultrasonic measurement of wind speed and wind direction.
  • OTT Parsivel²: Disdrometer for type and amount of precipitation.

Throughout the installation process, trained OTT HydroMet staff was on hand to make sure the setup of sensors and communication accessories was failure-free.

This information has been sourced, reviewed and adapted from materials provided by OTT HydroMet. Lufft is one of OTT HydroMet's strong brands for professional environmental monitoring.
