Inline Viscometer: L-Vis 510

L-Vis 510 is an inline viscometer which is immersed directly in the production liquid. It continuously displays the viscosity and temperature of lubricants, starch adhesives, suspensions, and many more process liquids, allowing 24-hour production monitoring. L-Vis 510 is available in three versions: L-Vis 510 Smart Sensor combined with an mPDS 5 evaluation unit L-Vis 510 Smart Sensor with Operating Terminal (OT) - the measurement values are displayed directly on the instrument, no evaluation unit is required L-Vis 510 Smart Sensor with a Remote Operating Terminal (ROT) which can be mounted at a distance of up to 250 meters from the sensor.
