INSTALLATION - DIRECT MODE WITH TRANSDUCERS, MOUNTING FRAMES
For Direct Mode mounting, you will use a spacer bar to establish the distance between transducers
and a Mounting Guide to easily locate the transducers at the nine o'clock and three o'clock positions.
Should the distance between transducers be beyond the span of a spacer bar, a measuring tape can
be used. The Mylar Mounting Guide comes in various lengths and widths to accommodate most pipe
sizes (see list below).
1. Perform all the required menu steps up until the point where the flow computer issues the number
index and prompts you to press <ENTER> to finish the transducer install routine.
Make a note of the number index displayed in the Pick/Install menu. Check to ensure that you have
a matched set of transducers. They both should have the same S/N number but marked with either
an "A" or "B" (e.g., 100A and 100B).
