2.4.2 HOW TO SELECT A TRANSDUCER SIZE

When you move the cursor to Transducer Size, the highlighted prompt at the top of the display screen shows a list of recommended transducer sizes. For example [Recommended Xdcrs: D3,D2,D1,C1,C3]. The flow computer generates this list automatically based on your pipe and your application data entries. The left-most transducer size (e.g., D3) is the primary (most appropriate) choice. The right-most transducer (e.g., C3) is still acceptable (but the least desirable) choice. Since these are simply recommendations not requirements, you can override the flow computer and use any size, as long as the mounting method accommodates the pipe’s diameter. The flow computer shows that your selection is acceptable if it is able to calculate transducer spacing (Ltn).

2.4.3 HOW TO SELECT A TRANSDUCER MOUNT MODE

The flow computer recommends the transducer mounting mode [Direct or Reflect]. In almost all cases it will be Reflect, since this is the most desirable configuration. Reflect mode allows you to mount the transducers on pipes that do not permit back or side access. Reflect mode provides inherent compen- sation for flow profile distortion (crossflow) that could be the result of unfavorable application conditions such as an insufficient upstream straight run. In addition, Reflect mode supports the AutoZero function, which sets the zero flow velocity automatically.

Direct mounting may produce a stronger transducer signal and requires less mounting length than Reflect mounting. This can be important if the liquid or pipe material exhibits high sonic attenuation, thereby preventing operation in the Reflect configuration.

NOTE: We recommend using Direct Mount with Plastic pipes.
