The Key to Energy Efficiency

“In the real estate industry you always hear this phrase, ‘Location, location, location.’ I think for energy management systems the key is ‘Execution, execution, execution.'”[1]

— Sara Lisauskas, Energy Management Systems: Maximizing Energy Savings

What comes to mind when you think of the phrase “energy efficient?” Perhaps you think of LED light bulbs, electric cars, Energy Star appliances, or LEED-certified buildings. But energy efficiency isn’t limited to “green” products or certifications. Continue reading “The Key to Energy Efficiency”

Flowmeter Used in an Energy Monitoring System Application

We recently met with a customer in India who needed to replace a flowmeter in an Energy Monitoring System (EMS) application in a commercial shopping mall.

Energy Monitoring Systems (EMS) continuously monitor and record chiller operating data. The EMS utilizes flowmeters installed in each chiller to measure flow. Temperature sensors are located in the inlet and outlet of the evaporators and condensers. A kWh meter measures the power consumption of each chiller. The data from each of these devices is collected and recorded within the control panel, which is then sent to a report generated in the cloud. This kind of system can accurately report the data used to manage energy and operating costs.

Because the space was occupied, the application couldn’t be shut down for maintenance or repairs. This meant that we needed to look into alternative solutions that wouldn’t affect system operations with unnecessary downtime.
