General information
The DXN portable ultrasonic flow meter is a true hybrid ultrasonic flow meter, capable of measuring liquid flow with multiple technologies, including: Doppler, transit-time and liquid thermal (heat energy) flow.
DXN is also compatible with a pipe wall thickness gauge, used to verify inside pipe diameter and ensure highly accurate ultrasonic measurements when piping details are unknown or unavailable.
The DXN has a number of advanced features that allow the user to obtain accurate readings while capturing flow surges and high-speed batch operations.
DXN captures and records multiple application parameters at one time with an easy-to-use data logging function and provides the power to verify and troubleshoot permanent flow installations with ease.

Measuring principle
Heat meters
The heat meters use the highly precise ultrasonic transit time measuring principle, for which two ultrasonic sensors are externally mounted on the pipeline and connected to the electronic. The ultrasonic sensors work alternately as transmitter and receiver, and mutually send ultrasonic signals. During these transmissions, the respective signal transit times of the to-and-from signals (t1, t2) are measured.
The electronic measures the difference of the transit time of the ultrasonic signals going with and against the flow direction t1 and t2. These signals are either decelerated or accelerated by the medium flow. The difference produced in both signal transit times is proportional to the flow rate and is used together with the pipeline geometry for a precise flow calculation
