Attaching The Transducers In Diagonal Mode - GF U3000 V2 Betriebsanleitung

Installation
10. Lower the transducers onto the pipe by turning each transducer clamp anti-clockwise until it is 'finger tight' (do not use a span-
ner). The figure below shows the final position of the transducers when the transducer clamps are fully tightened.
11. Connect the transducer signal cables to the U3000 V2 instrument – i.e. with the RED cable
connected to the upstream transducer connector and the BLUE cable to the downstream
transducer connector.
NOTICE
If you observe negative flow, swap the red and blue cables at the sensor end.

Attaching the transducers in diagonal mode

This mode of operation requires two transducer guide rails fitted on opposite sides of the pipe (fitted on a 45° axis with respect to
the top of the pipe as in Reflex Mode). If the required transducer separation is 230mm or less, the guide rails can be fitted using the
same stainless steel bands (see figure below). For greater transducer separation, the guide rails may need to be installed sepa-
rately (see Figure below). In this case, it is necessary to accurately mark out the required positions to ensure that the transducers
are correctly positioned and aligned along the axis of the pipe, directly opposite each other on a 45° axis with respect to the top of
the pipe, and at the required separation.
To position the transducers, obtain and note the separation distance between the transducers using the Quick Start menu (see
section 'Using the quick start menu'). Prepare the transducers with couplant as described in section before.
