Chapter 3. Inserting T9 Transducers into the Pipe
3.1 Introduction
The T9 transducer is typically installed into a meter body. The meter body is a section of pipe that contains the ports
where the transducers will be mounted. The meter body may be prefabricated or created by installing ports on the
existing pipe. The T9 can be inserted into the pipes using a number of methods:
•
Simple Holder
•
Barrel Holder
•
Flanged Holder
3.2 Inserting Transducers with the Simple Holder
The simple holder consists of a flange with a compression fitting tapped or welded in the middle of the flange.
Transducers are usually installed in a diagonal 45
o
configuration, although other configurations are available.
The procedure below applies to a diagonal 45
o
single-traverse configuration when the transducer insertion depth does
not exceed the pipe inside diameter. Consult GE for other configurations.
IMPORTANT:
If you do not know the transducer insertion depth, measure the length of the nozzle (from the top of the
nozzle to the pipe) and then add the pipe ID to that measurement. If this measurement equals the Z
dimension, then the transducer insertion depth does not exceed the pipe ID.
Use the steps below to insert the simple holder.
1.
Measure the Z dimension as shown below. The Z dimension is set at the factory and should be verified.
