Depending on the installation point requirements of the fiber line, there are two types of SAFE-DRIVE™ Process Refractometer PR-23-SD systems specifically designed for reliablitity and easy installation directly in the process pipe line:

  • SAFE-DRIVE™ Process Refractometer PR-23-SD with steam prism wash for filtrates and weak black liquor lines
  • SAFE-DRIVE™ Process Refractometer PR-23-SD with special isolation valve and installation plate for the blow line and the pulp stock line.

Performance features of SAFE-DRIVE™ process refractometer in the BSW application

  • Indicates total dissolved solids (TDS) in solution
  • Suitable for all concentrations
  • Measures precise concentration of washable liquid substances
  • Detects organic materials with a large molecular size, such as lignin
  • Not influenced by chemical oxygen demand (COD) caused by methanol
  • In-line real-time measurement, immediate response time, suitable control
  • Mounted directly onto the pulp line
  • Low operating costs, maintenance-free

K-Patents SAFE-DRIVE™ design allows for safe and easy insertion and retraction of the sensor under full operating pressure without having to shut down the process (Patent No. 2051111).

The measurement range covers 0-100 % by weight. The accuracy is typically ±0.1 % b.w. and the measurement is automatically temperature compensated. Low and high concentration alarms can be configured. Because of the digital sensing technology, even large amounts of suspended solids, bubbles or color changes do not affect the measurement or the accuracy.
