Sodium Hydroxide Level Measurement

With global demand at 61M tons per year, sodium hydroxide, also known as caustic soda is the most widely used chemical base. Pure caustic, a pelletized solid, is handled as an aqueous solution to neutralize acidic material or drive chemical reactions. Typical applications include water & wastewater treatment, metal etching, food preparation, aluminum production, cleaners and detergents. When exposed to air, caustic undergoes an exothermic reaction and crystallizes, coating everything it contacts. Here, the EchoSafe explosion proof ultrasonic level sensor provides reliable non-contact measurement of sodium hydroxide in a hazardous environment.

Petrochemical Hazardous Level Measurement

Refined chemicals are the building blocks of modern products from plastic to aspirin, paint to fertilizer and clothing to detergent. Worldwide there are more than 2900 petrochemical plants in 4300 locations that manufacture refined chemicals from petroleum and hydrocarbon based material. The majority of these manufacturers are located in North America and Europe, but new production facilities are shifting to Austral Asia. Chemical plants are hazardous environments that require explosion proof or intrinsically safe certified instrumentation. Here, an EchoSafe explosion proof ultrasonic level transmitter is installed on the man-way cover of an underground wastewater bulk storage tank. The patented digital signal processing technology features an industry leading 3" beam width that enables installation in close proximity to the 6" suction pipe.
