scale orloose paintand make a smooth surface. Choose asection ofsound conductingpipe forinstalling the
transducers.Applya wide ban

well ason the pipe surface,
ensure there are no air bubblesbetween the transducers and the pipe wall,
attach the transducers to the pipe with the strapsprovided and tighten themsecurely.
Note:
The
two transducers shouldbe mounted atthe pipe’scenterline on horizontalpipes.
Make sure thatthe transducermounting direction isparallelwith the flow.
During the installation, thereshould be no air bubblesorparticlesbetween the transducerand the
horizontalpipes, the transducers should bemounted in the 3 o’clock and 9o’clock positionsofthe pipe section in
orderto avoid anyair bubblesinside the top portion ofthe pipe. (Referto TransducerMounting). Ifthe
