Keeps pure water on the move
March 1st 2008 Ongoing, reliable flow
measurement as part of a
water quality monitoring
system, is an important
requirement at Glaxo Smith-
Kline's manufacturing plant
in Harlow, where a
significant amount of WFI,
'Ultra Pure water' is used.
To eliminate the potential
for purification faults, the
water needs to be kept
circulating in the ring main
pipe work at a constant 85
to 90°C. When laboratories
need water, it is fed through
a chiller and delivered at a
constant 15°C.
Turbine meters installed
as part of the monitoring
system caused problems as
a result of bearing failure.
The solution was provided
by non-contact,
clamp-on ultrasonic
meters supplied by
Flowline. The noninvasive
Minisonic
devices were
installed without the
need for shutdown,
and rigorous testing
has shown that the flow
meters can handle
fluctuating temperature
without inducing errors on
the measurement. More articles from Flowline Manufacturing Ltd: |
