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.

RoHS stands for the Restriction of Hazardous Substances in electrical and electronic equipment. RoHS, also known as Directive 2002/95/EC, originated in the European Union and restricts the use of specific hazardous materials, and impacts a wide array of products in the electronics industry.

Air flow pressure switches and differential pressure switches work just like the light switches we have in our living rooms at home: when they are switched on, the switch makes contact, closes the circuit, and turns on. When they are switched off, the circuit is broken and power turns off. With air flow switches, instead of being manually switched, the air flow switch closes or opens the contact by reacting to changes in the air pressure at a pre-set actuation point, and turns on and off accordingly. These air pressure switches may be used to start/stop motors or fans, open/close dampers or louvers, sound alarms, and more. Continue reading “Let’s Chat About Air Pressure Switches!”
A dust collector is a system used to improve the quality of air within an industrial and commercial environment by collecting dust and other impurities from the air. Continue reading “Maintain Continuous Operation from Leaking Pulse-Jet Bag Filters”
Calibration is the comparison and adjustment of a reading from an instrument in correlation with the reading of a higher accuracy piece of equipment. The overall goal of this process is to minimize measurement uncertainty and ensure the accuracy of an instrument.
