4.3 Equipment Information
The FGM 160 requires +24 VDC power supply (nominal). If 24 VDC is not available,
an optional 110-230 VAC/24 VDC converter can be supplied by Fluenta.

5. TRANSDUCER/PROBE INSTALLATION
5.1 Installation of Transducer Holders
There are three alternatives for mounting the transducer holders. The first uses a metering
spool piece that has the transducer, pressure, and temperature holders already installed.
The second is referred to as “Cold Tapping”, where the holders are installed on a section
of pipe that is shut off from the flare system. The third option is referred to as “Hot Tapping”,
where the holders are mounted onto a flare pipe that is active. The metering spool piece is
assembled in a mechanical workshop, and “Cold Tapping” and “Hot Tapping” are done by
welders under the supervision of Fluenta personnel.
It is recommended that all of the above three methods are performed under Fluenta
supervision, including spool piece inspection and welding supervision.
5.1.1 Space Requirements
The space requirements around the pipe vary depending on transducer models and pipe
diameters. This will be covered in the following sections. The transducers must be mounted,
regardless of the pipe diameter or transducer model, on a straight section of pipe. The length
of this straight section must be at least 15 times the diameter of the pipe. The nearest
upstream disturbance must be at least 10 times the diameter of the pipe away from the
center of the metering section, and the nearest downstream disturbance must be at least 5
times the diameter of the pipe long. These distances are illustrated in Figure 1. For
installations that cannot meet these requirements, Fluenta should be contacted as this may
have an effect on the measurement uncertainty. As this product is a fiscal measurement
system, this effect should be evaluated.
