T-Slot transducer removal and installation

The T-Slot transducer assembly offers improved transducer alignment and superior
acoustic isolation between the transducer and the meter housing.
The net result is improved performance and stability. The assembly is used on Rosemount
3414, 3412 and 3411 meters and is line pressure vented. The gas temperature ranges are
shown in
