Vaisala K-PATENTS SAFE-DRIVE Process Refractometer PR-23-SD for brown stock total dissolved solids (TDS) control and optimization
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 reliability and easy installation directly in the process pipeline:
Performance features of SAFE-DRIVE Process refractometer in the BSW application
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.
