The winter of 2013-2014 devastated the Midwest and Northeast regions of the United States with record snowfall and temperatures. For example, Chicago which averages 38″ of annual snowfall, received 82″ of snow which severely stressed municipalities as they outspent their annual snow removal budgets, and struggled to keep their roads open. One of the most effective tactics available to maintenance crews is the pre-storm treatment of their roadways with salt brine (sodium chloride or rock salt dissolved in water to a salinity of 23%). As brine has a lower freezing point than water, it’s an excellent de-icing agent that reduces snow or ice build up above 15° F. (-9° C.). Therefore, brine treated roads return to normal conditions much faster than untreated roads, resulting in fewer accidents and delays. During winter, municipalities keep thousands of gallons of brine solution at the ready. At this New Jersey road maintenance facility, an EchoTouch ultrasonic level transmitter is installed in each of their brine storage tanks. The intrinsically safe sensors are located in a hazardous area near the truck refueling station.
