According to the American Hospital Association (AHA), there are 16,000 hospitals in the United States and 90% of these require deionized water for several of their processes. City water contains cations like sodium, calcium, iron or copper and anions such as chloride and sulfate. All of which, can contaminate parts or cause reactions when mixed with chemicals that may interfere with patient care. As a result, hospitals widely deploy reverse osmosis and deionized water systems to remove such contaminants, and provide ultrapure water to their facilities. The process of deionization involves the use of specially resins that exchange hydrogen ions with dissolved minerals to neutralize ions. Here, an EchoSwitch ultrasonic level controller is installed on the deionized water storage tank. When the level drops to a low level, the sensors relay actuates a valve to refill the tank. The non-contact sensor provides reliable ultrapure water level measurement.
