the instrument’s microprocessor can use the results of the transit time calculations to compute the fluid flow
velocity. Once the flow velocity is known the volumetric flow can be easily calculated for a given pipe diameter.
The system can be set up to operate in one of four modes, determined mainly by the pipe diameter and the type
of transducer set in use. The diagram in Figure 1.1 illustrates the importance of applying the correct separation
distance between the transducers to obtain the strongest, and therefore most reliable, signal.
1.3 Supplied Hardware
The supplied UFC components are shown in Figure 1.2.
