(57) Abstract:
A flow meter incorporating thermal loss sensors and an
installation adapter to provide known flow conditions
upstream of the meter. The installation adapter is in the
form of a tubular extension projecting from a flange
which in use is sandwiched between a pipeline flange and
a flow meter flange. The flanges are configured such that
a passageway defined by the adapter extension is located
in a predetermined position relative to the flow meter.
The flow meter may comprise a sensor array supporting
at least three sensors which are not in alignment, one of
those sensors being located centrally within the flow
meter and the others being distributed at equal distances
around the central position. In use, normal readings may
be taken from a single one of the sensors, the other
sensors being used for initial calibration and subsequent
calibration test purposes only. A comparison is made
between the relative values of the outputs of the different
sensors to identify sensor drift or potentially significant
changes in flow conditions.
