Dynasonics

Dynasonics

Dynasonics, a Badger Meter brand based in Racine, Wisconsin (USA), specializes in non-invasive clamp-on and portable ultrasonic flow measurement, best known for its TFX series fixed clamp-on meters and DXN series portable flowmeters spanning transit-time and Doppler technology for liquids, heat, and thermal energy applications. Dynasonics instruments serve water and wastewater utilities, HVAC and district cooling systems, industrial process plants, and municipal infrastructure where non-invasive, clamp-on measurement avoids pipe cutting, process shutdown, or contamination risk. The TFX series delivers fixed, permanently installed transmitters for continuous flow monitoring across a wide range of pipe sizes and materials, while the DXN portable series and DFX Doppler meters extend coverage into field troubleshooting, aerated or particulate-laden liquids, and rapid site surveys. Seven Star LLC supplies genuine Dynasonics clamp-on and portable ultrasonic flow measurement instruments to water authorities, industrial facilities, and process engineers across Oman and the wider GCC region.

Frequently Asked Questions

How does a Dynasonics clamp-on flowmeter measure flow without cutting the pipe?
Transducers are strapped to the outside of the pipe and measure the transit-time difference of ultrasonic pulses sent with and against the flow. No pipe cutting, process shutdown or wetted parts are required.
When should I choose a Doppler meter instead of a transit-time meter?
Transit-time meters suit clean or mildly dirty liquids, while Doppler models such as the DFX need suspended particles or entrained bubbles to reflect the signal. Slurries, raw sewage and aerated liquids are typical Doppler duties.
Can Dynasonics TFX meters measure thermal energy for HVAC systems?
Yes, energy versions pair the flow transducers with matched RTD temperature sensors to calculate BTU or kWh consumption. This is common in district cooling and chilled-water metering.
What outputs do Dynasonics transmitters provide for SCADA or BMS integration?
Typical outputs include 4-20 mA, pulse/frequency and relay alarms, with Modbus RTU and BACnet options on selected models. This allows direct connection to PLC, SCADA and building management systems.
Are portable Dynasonics meters suitable for site surveys?
The DXN portable series is battery powered with a data logger and is designed for temporary surveys, meter verification and troubleshooting. Engineers can move it between pipes of different sizes and materials.
