Ferric Acid Tank Level Measurement

		Transportation of chemicals in the U.S. is a $40 billion a year industry, representing almost 8% of the chemical industry's cost of sales. Chemical transportation by rail represents 12.6% of revenue for large freight Class I railroads, making storage and safety an important factor for railroad industry success. Ferric chloride, a preferred wastewater treatment chemical, is a moderately strong Lewis Acid used in sewage treatment, drinking water production as well as a metal etchant for copper and stainless steel. The favored mode of transportation for this chemical is by railcar. At a railway station in the Southeast, aqueous ferric chloride is contained in bulk tanks prior to it being transported into sewage treatment plants. Ferric chloride is used as a wastewater coagulant, ideal for process treatment as it absorbs phosphorus and other heavy metals that creates a sludge. This sludge byproduct with its contaminants is then separated from the water and treated before disposal.
A non-contact level solution was required for this application due to tank height and caustic contents. EchoSpan® is the perfect measurement application due to it's 32.8' (10m) range, simple push button configuration and is ideally suited for corrosive liquids with its PVDF transducer and NEMA 4X enclosure.
