Our latest feature allows users to manually adjust the number of ultrasound traverses across a pipe. While the flowmeter defaults to an optimized setting, certain fluid or pipe conditions may benefit from a different transducer arrangement. In such cases, manual selection is recommended.
Transducer arrangement determines how transducers are mounted—either on opposite sides or the same side of the pipe—and how many times ultrasound crosses the pipe. Figure 1 illustrates the available configurations:
CMxx models (transducers on opposite sides) support 1 or 3 traverses (“I” or “Z”).
Cxx models (transducers on the same side) support 2 or 4 traverses (“V” or “W”).
For small pipes, automatic mode may increase traverses, which isn’t always ideal for pipes with corrosion, scaling, particulates, or microbubbles, as these can dampen signal strength. In such cases, selecting the minimum necessary traverses (“I” for CMxx or “V” for Cxx) is recommended.
Conversely, if the installation is highly acoustically conductive—such as clean metal pipes with clear fluids—increasing the number of traverses can enhance measurement accuracy. This is beneficial for small to medium-sized metal pipes but not for large pipes, where the ultrasound already spends significant time in the fluid.
How to Enable Manual Transducer Configuration
To manually adjust the transducer arrangement, access Advanced Setup (Fig. 2):
From the measurement screen, select “Edit” → “Advanced” → “Transducer Arrangement.”
Toggle “Manual Control” to “Yes.”
Choose the appropriate configuration based on your flowmeter model.
By fine-tuning these settings, you can optimize performance for specific pipe and fluid conditions.
