Siemens SITRANS FUS1010 NEMA-4X/ IP 65 manual Mounting the Transducers

Section 7 1010NFM-3J

7.4MOUNTING 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).
