Liquiphant M density meter

By providing online measurements, the Liquiphant M density meter eliminates the need for extensive and expensive offline procedures and laboratory measurements. Online measurements allow control systems to react more quickly than when offline systems are used. The meter’s built-in density calculator can be customized by inputting complex tables and mathematical relationships. Its mechanically oscillating, two-tined fork is excited by a piezoelectric drive to resonant frequency, which changes whenever the fork is immersed in liquid. The sensor reports whenever the vibration falls below a predetermined frequency. In a lower-density medium, such as liquefied gas, the resonant frequency is higher than in higher-density materials, such as water. This meter is suitable for use in the food industry to determine the sugar content in fruit juices and beverages, as well as in oil production to measure the salt concentration in tanks.
