Emerson Daniel 3415

WARNING!
CRUSHING HAZARD
During meter installation or removal, always place the unit on a stable platform or surface that
supports its assembled weight.
Failure to comply could allow the meter to roll, resulting in serious injury or equipment
damage.
For basic maintenance, refer to Section 1.2.
3.2 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 Daniel 3417, 3416 and 3415
meters and is line pressure vented. The gas temperature ranges are as show in
Temperature ranges for transducers, mounts and holders.

3.2.1 Transducer removal
1. Blow the line down according to the site standard operating procedures.
2. Ensure that the line pressure is down to atmospheric pressure prior to disassembly.
3. Disconnect transducer cabling from the transducer assembly by removing the
