5.2 Mounting the Transducer Holders
There are three ways to mount the transducer holders. The first is by mounting a Spool piece
which is a pre-fabricated pipe with all of the holders (transducer, pressure, and temperature)
already mounted. This pre-fabricated spool piece is inserted into the existing flare pipe
system. The second option is to perform Cold Tapping which means that the transducer
holders are mounted directly onto a flare pipe which has been temporarily removed or cut off
from the flare system. The last option is Hot Tapping which means that the transducer
holders are mounted directly onto a pipe that is being used by the flare system. Due to the
dangerous nature of this option, it is performed by a third party specialist, under supervision
of Fluenta personnel.
5.2.1 Orientation
5.2.1.1 Horizontal Flare Pipe
The optimal orientation of the transducers on the flare pipe depends on whether the flare
pipe is horizontal, vertical, or inclined at a certain angle. If the transducer holders are to be
installed on a horizontal section of the flare line, the transducers should be horizontally
oriented as shown left in Figure 3. The reason for this is that there may be fluid accumulation
in the flare pipe, and if the transducers are oriented in any other way than horizontally, fluids
might accumulate in the lower transducer holder. Then, the fluid must be drained to ensure
the functionality of the meter.
