Daniel T-20 Series Gas Ultrasonic Transducers

Robust design for continuous, reliable performance

The new more robust T-20 Series Gas Transducer design is now the new standard for all Daniel gas ultrasonic flow meters.  Daniel’s unique ultrasonic transducer design continues to be one of the vital elements enabling Daniel ultrasonic meters to perform to the highest industry standards. 

The new T-20 Series Gas Ultrasonic Transducers (T-21 and T-22) expand on the capabilities of the Daniel T-10 Series transducers (T-11 and T-12) to provide increased longevity. The new transducers are more tolerant of corrosive fluids in harsh environments or any wet, rich, or dirty gas application.

Engineered for performance and ease of use, the new design features a non-wetted transformer located outside the pressurized process, preventing exposure to liquid borne dirt and corrosive process fluids. Robust electrical connectors with six raised surfaces minimize contaminant build-up.

  • The separation of the transformer from the transducer capsule extends the life of the transducer components in all environments, as well as improves the overall performance by increasing the signal voltage from the piezoelectric crystal for a stronger, continuous electrical connection. 
  • Minimizing the effect of debris and removing components from the process effectively reduces maintenance and enables the operator to troubleshoot or replace the transformer without depressurizing the meter.

 For specifications and additional information, refer to the T-20 Series Gas Ultrasonic Transducer Flyer.

SeniorSonic and JuniorSonic Customers: Upgrade your existing meters to new T-20 Series transducers. Engineered for direct in-line replacement of Daniel T-11 or T-12 transducers in most cases, learn​ more about how conversion can be handled quickly. Contact your nearest Daniel Sales and Service office for more information.
