Brewery uses turbidimeter to constantly monitor beer clarity
McNab HSB turbidimeter (turbidity monitoring system) was installed at a brewery to control beer haze and continuously monitor clarity.
To assure consistent product quality, a leading European brewery needed more than visual inspection to control beer haze.
A high-sensitivity turbidity monitoring system was installed to continuously monitor clarity and to alert plant personnel when turbidity exceeded established standards.
The brewery installed a
Model HSB turbidimeter system in the beer line right after the
filter press and before the beer enters the single tanks.
The system consists of an indicator/control cabinet electronically connected to a flow cell with four mounted waterproof housings.
One housing contains the light source. Two housings are mounted at 90° angles from the light source: one holding the measuring detector and the other containing a test lamp and light trap.
The fourth housing. mounted directly opposite the light source serves as a reference detector and is used to measure transmitted light so as to provide a ratio to compensate for variations in color bulb deterioration and/or the fouling of optical surfaces.
Light striking a particle is reflected at various angles from the light beam. The Model HSB continuously gauges solids content by measuring the light scattered off of particles at a 90° angle from the direct light beam.
Signals are sent from
the detector to the indicator/control cabinet, where they are converted
to turbidity measuring units and digitally displayed.
Also contained in the cabinet is a relay that sounds an alarm and
turns on a red light when turbidity levels fall out of the acceptable
range. and a continuous datalogger to provide a record of product
When the alarm sounds,
plant personnel investigate the problem and advise the brewmaster.
The brewmaster speaks quite highly about the turbidimeter
monitoring system, saying “It takes the guesswork out of haze control.
it keeps our personnel on their toes and it lets us put out a consistent
HSB turbidity indicator/controller is now used by breweries
throughout Europe, North America and South America to monitor and
