Simple Installation. Enhanced Monitoring.

The Dynasonics DXN Portable Hybrid Ultrasonic Flow Meter is a true hybrid instrument, capable of measuring liquid flow with multiple technologies to provide accurate readings.

Application Flexibility. Equipped to read Doppler, transit time and liquid thermal (heat energy) flow and will automatically choose the type of flow measurement based on the signal quality during operation.

Streamlined Installation. Can be installed and set up by a single individual by clamping the meter onto the pipe—does not require operations to be drained or shut down.

Advanced Features. Equipped with a touchscreen interface, full-color graphing, wizard-based start-up configuration, USB connectivity and Modbus TCP/IP connectivity.


Transit time flow meters measure the time difference between the travel time of an ultrasound wave going with the fluid flow and then against the fluid flow. This time difference is used to calculate the velocity of the fluid traveling in a closed-pipe system. The transducers used in transit time measurements operate alternately as transmitters and receivers. Transit time measurements are bi-directional and are most effective for fluids that have low concentrations of suspended solids.
