Table 2.2 - Transducer Mounting Modes — FST4, FST5
For further details, reference Figure 2.1. The appropriate mounting configuration is
based on pipe and liquid characteristics. Selection of the proper transducer mounting
method is not entirely predictable and many times is an iterative process. Table 2.2
contains recommended mounting configurations for common applications. These
recommended configurations may need to be modified for specific applications
if such things as aeration, suspended solids, out of round piping or poor piping
conditions are present. Use of meter diagnostics in determining the optimum
transducer mounting is covered later in this section.

Step 3 - Entering Pipe and Liquid Data
The system calculates proper transducer spacing by utilizing piping and liquid
information entered by the user. Enter this information via the keypad or via the
optional software utility.
The best accuracy is achieved when transducer spacing is exactly what the meter
calculates, so use the calculated spacing if signal strength is satisfactory. If the pipe is
not round, the wall thickness is not correct, or the actual liquid being measured has a
different sound speed than the liquid programmed into the transmitter, the spacing
can vary from the calculated value. If that is the case, place the transducers sat the
highest signal level observed by moving the transducers slowly around the mount
area.
Note: Transducer spacing is calculated on "ideal" pipe. Ideal pipe is almost never found so the
transducer spacing distances may need to be altered. An effective way to maximize signal strength
is to configure the display to show signal strength, fix one transducer on the pipe and then starting
at the calculated spacing, move the remaining transducer small distances forward and back to
find the maximum signal strength point.
Important! Enter all of the data on this list, save the data, and reset the
meter before mounting transducers.
