4.1 Choosing an Installation Location
To select a suitable transducer location, complete the following steps:
1. Locate the transducer measurement point at least 3 ft (1 m) from any butt welds or flanges. Ideally the location
would be in the center of a 20 ft (6 m) section of straight pipe. Make sure there is sufficient clearance on both sides
of the pipe for easy transducer installation:
•
6 in. (15 cm) if you are not using a junction box, or
•
9 in. (22.5 cm) if you are using a junction box.
Note: To guarantee the specified accuracy of the flowmeter, a straight section of pipe and a fully-developed flow
profile are highly recommended. If such conditions are not possible, the transducer location should be such
that the acoustic signal travels through the full distribution of the under-developed flow profile for best
repeatability.
2. Place the transducers as close as possible to the horizontal plane of the pipe (see Figure 2). Locate the transducers
on opposite sides of the pipe 180
Do not place transducers on the top or bottom of the pipe.
IMPORTANT:
Note: For the best flow profile identification in limited straight section of pipe, place the transducers at 1 and 7
o'clock.
