The Dynasonics DXN portable clamp-on ultrasonic flowmeter from Badger Meter is easy to install by clamping to the outside of the pipe. It measures flow using noninvasive ultrasonic sensors and can be easily moved. A large color display makes it easy to read while the setup wizard walks the operator through the meter configuration steps. Settings can be saved for future use. Its portability allows measurements throughout process system infrastructure. Besides measuring liquid flow rate, it can calculate hydronic energy with a built-in calculator, making it easy to perform energy studies on heating and cooling loops. 877/243-1010; www.badgermeter.com.
