United States data centers consume 575 gigawatts or 2% of all the power consumed off the nations grid. Half of that energy is used to power computers and the other half is used to cool the computers. Two types of cooling systems are deployed including the newer rack cooling and older room cooling systems. Rack cooling systems work by directly cooling a computer rack versus the entire room. In this system, a wall of chilled water passes inches from the racks, neutralizing the heat released from the back of the servers. Rack cooling is highly efficient and cost effective. At this new US data center, chilled water continuously circulates between two underground concrete bulk storage tanks and the server room. An EchoSonic ultrasonic level transmitter is installed in each storage tank. The non-contact sensors provide continuous level data to the PLC. EchoSonic is reliable chilled water level measurement.
