Description
Pulsar DUET Dual Ultrasonic Echo Transducer provides the highest accuracy non-contact ultrasonic flow measurement system available anywhere. Only DUET features Pulsar’s unique, patented, approach to the issue of accuracy when temperature and echo reflection time varies.
Both transducers fire together. By continuously monitoring the phase difference of the echoes, and because the distance between the transducer faces is known and constant, the speed of sound is continuously updated in real time on the process. The resulting accuracy and stability is exceptional.
Features
- Unique patented non-contacting transducer
- Insensitive to air temperature variations
- 300mm deadband
- Most accurate open channel flow system in the world!
