The global pharmaceutical industry develops about 3,000 new medicines a year, addressing an array of health issues facing aging consumers. Given the extreme pace of new product development, production facilities are constantly retooling their manufacturing to meet the latest requirements. A relative constant is the chemical storage, water treatment, chemical feed and wastewater treatment equipment that supports their changing processes. At this US pharmaceutical company, an EchoSafe explosion proof ultrasonic level transmitter is installed on a sulfuric acid storage tank for inventory management. The non-contact sensor is FM approved for use in hazardous locations, and provides continuous level data to the PLC. EchoSafe is reliable hazardous level measurement.
