2.2.1 Fitting the transducers
1. Slide the transducer cover plate 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 3 mm bead of ultrasonic couplant along the centre length of the transducer.
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.
5. Slide the transducer cover plate over the top of the transducer and tighten the thumbscrew finger-tight to secure the transduc-
er in place. When securing the cover plate take care to leave sufficient room around the transducer connector to connect the
cable.
6. Repeat the above steps for the second transducer.
7. Connect the transducers to the flowmeter unit using the coaxial cables provided. The RED cable must be connected to the up-
stream transducer and the BLUE cable to the downstream transducer. The sockets are also colour-coded.
NOTICE
If you observe negative flow, swap the red and blue cables at the sensor end.
