Recorder role
November 1st 2008 Videographic recording technology
from ABB is being used to improve
performance at two water
treatment works in South Wales.
An SM3000 videographic
recorder at the Carno treatment
works lets operators see what's
happening throughout the plant
instantly from the control room.
Steve Curnow, instrumentation
and control technician, says "The
SM3000 has given us 30 channels,
so practically every instrument on
site is now hooked up to the
control room. It's been very helpful
because it means we can see
what's happening straight away."
The Carno treatment works has
also installed an SM2000 recorder
for the triple-validation control of
pH. The recorder takes signals
from three separate pH measuring
systems and calculates the
average. This is then used to
control the plant's dosing pumps.
Two more SM2000 recorders
have replaced four older recorders
at Cwm Tillery works near Abertillery. More articles from ABB Ltd: |
