MOUNTING THE TRANSDUCERS
Two mounting configurations are available. Adjacent mounting locates the two transducers alongside
each other using a single mounting chain or strap. In-Line mounting locates the two transducers axially
along the pipe using two mounting chains or straps. On metal pipes the Receive Transducer is always
located behind the Transmit Transducer. On plastic pipes the Transmit Transducer is always located
behind the Receive Transducer. In both cases, the cable entry will be on the same end of both trans-
ducers unlike the transit-time configurations. Adjacent mounting will provide the maximum sensitivity to
flow. Refer to the appropriate transducer installation drawing for the 191N1S (Installation Drawing
191N1S-7).
