Fixed ratio control requires the quality of both
the raw water and the pure water to remain
consistent. To achieve this, flowmeters are used
on both lines and a control valve is used to
deliver the correct ratio for the blended water.
The alternative is to use a water quality monitor
that is set up to measure a parameter, such as
conductivity. This monitor is linked to the water
supply valves via a control loop that regulates
the blending proportionally and can therefore
compensate for variations in supply quality.
Designing and creating these control systems
requires considerable expertise to ensure that
they perform reliably and are properly integrated
with the surrounding control infrastructure.
Process control experts at Bürkert have created
an extensive range of compatible flow control
and quality measurement products that can be
combined to deliver an optimised quality control
system that can be scaled to suit any process.
