If you are unable to get sufficient tension on the chain to hold the assembly in place,
fully slacken the tensioning thumb-wheel and shorten the effective length of the chain
wrapped around the pipe by connecting the tensioning bar to the next link in the chain,
then re-tension.

1. Slide the transducer cover plate (A) fully towards the outside of the guide assembly to
allow sufficient access to fit the transducer.
2. Clean the face of the transducer, removing all traces of dirt and grease.
3. Apply a 3mm bead of ultrasonic couplant along the centre length of the transducer (E).
4. Fit the transducer into the guide block – ensuring the lugs on the sides of the transducer
are correctly located into the slots on the sides of the guide block (B).
5. Slide the transducer cover plate (A) over the top of the transducer and tighten the
thumbscrew (C) finger tight to secure the transducer in place. When securing the cover
plate take care to leave sufficient room around the transducer connector (D) to connect
the cable.
6. Repeat the above steps for the second transducer.
7. Connect the transducers to the Portaflow instrument using the coaxial cables provided.
The RED cable must be connected to the upstream transducer and the BLUE cable to the
downstream transducer. If you observe a negative flow, swap the red and blue cables at
the sensor end.
