Valmet RM3 – Total and True Ash Consistency Measurement, Ideal for Wet End Monitoring and Control • Ash retention 0–100 % • ick stock ash content 0–50 % Suitable for all pulp types. Versatile user interfaces: TCU • FieldCare™ based PC connection • DCS con- nection via analog outputs e Valmet RM3 wet end sensor measures online the total and true ash consistency. It is based on 20 years’ experience in optical consistency measurements and represents the third generation of industry-standard Valmet technology. It is the only optical measurement on the market capable of measuring both total and true ash consistency from a process sample. e Valmet RM3 is a versatile, reliable, continuous window into the wet end. Specifications Valmet RM3 utilizes the continuous sample flow when measuring the following • Total consistency 0–2.0 %; (0–20 g/l) • Ash consistency 0–1.0 %; (0–10 g/l) • Flocculation index • Total retention 0–100 % Valmet Retention Measurement
