Demand is high for new level sensing technologies in China and India and in many markets around the world. New products, such as ultrasonic level meters and guided-wave microwave level gauges, are attractive to the water, wastewater and agriculture markets, according to a research report from Frost & Sullivan. Level sensors are also used in cases where the level measurement would represent the leak rate in larger tanks. The other applications are in aerobic septic systems, pumping stations, chemical feed, sedimentation, mixing vessels and chlorine removal.
Another area of growth is in the food-handling equipment, beverages, pharmaceutical and packaging industries where demand for level sensors that conform to 3-A standards is important. Apart from conformance to 3-A standards, level sensors that come with clean-in-place (CIP) and sterilize-in-place (SIP) capability are attractive choices for users needing the most modern cleaning and sanitizing methods.
Newer to the market are combination sensing devices, multivariable and dual sensors that not only can measure level, but also one more parameter, such as temperature.These level sensors also include a graphical LCD and a visual alarm. The alarm alerts the operator when the programmed parameters are outside the preset ranges.
Finally, according to ARC Advisory Group, “The worldwide market for radar level devices is expected to grow at a compounded annual growth rate of 5.9% over the next five years. It will is forecasted to be $421 million in 2012.”
