PRINCIPLE OF OPERATION

The turbidity of the sugar solution is measured by measuring the absorption of light at a wave length of 88nm, passed through a sample of the solution. The instrument uses water as a reference and is automatically calibrated every hour.The absorbance is displayed locally and is available as a 4-20mA electrical signal.

APPLICATIONS

The instrument was originally designed to measure the turbidity of clear juice to check the operation of a clarifier. It can simply be used to monitor the combined clear juice output or can be used on each component when trying to localise problems in a clarifier. It has subsequently been used on a syrup clarifier and has been used to check the clarity of brown liquor and fine liquor in refineries.

BENEFITS OF A TURBIDITY METER

• Effective monitoring of combined clear juice output
• Simple Maintenance. Cleaning of cell windows required once a week
• Alarms for instrument malfunction and measurements exceeding set points
• Easy to use menu keypad
