Online Liquid Density Meter

Working Principle

The liquid density meter utilizes ultrasonic sensing technology to measure the transmission time of the sound wave from the signal source to the signal receiver. The direct correlation between speed of sound waves and liquid density helps in calculation of density reading. Waves travel slower in denser materials and faster in less dense ones. The density meter liquid is designed to address challenges in continuous density monitoring, serving as an inline density measurement instrument in data-driven process control. It enables manufacturers to shift from a reactive, crisis-management approach to a proactive model of continuous process optimization.
