Daniel T-200 transducer for gas ultrasonic flow meters

Wednesday, 08 April, 2020 | Supplied by: Emerson Automation Solutions


Emerson has released the Daniel T-200, a titanium-housed transducer, for its gas ultrasonic flow meter product line, utilising metal 3D printing to enhance the acoustic performance of ultrasonic flow meters in custody transfer applications.

Ultrasonic signal quality and strength are critical to measurement accuracy, which is paramount in custody transfer applications. To boost signal strength through the titanium housing, the T-200 uses a metal 3D-printed mini horn array, which consists of an intricate geometrical structure of titanium horns and a titanium diaphragm that acts as a harmonic oscillator and matching layer. This maximises the sound energy coupled into the gas, which improves the signal-to-noise ratio and accuracy of the measurement.

The meter’s all-metal housing provides a barrier from corrosive hydrocarbon fluids and wet gas, thereby extending the life of transducer components and ensuring stable performance. This design allows the meter to be hydrotested with transducers in place, steam cleaned while in the operating line and blown down with no limits on the rate at which the meter can be depressurised.

The T-200 can also be safely extracted while the meter is under pressure without special high-pressure extraction tools, which reduces the possibility of greenhouse gas emissions during extraction. The capsule which contains the piezoelectric crystal is retractable as a single piece for simplicity and ease of use.

The T-200 is rated for a wide range of operating conditions, including pressures from 15 psig/103 kPa to 3750 psig/25,855 kPa and temperatures up to 125°C.
