Overview:

    When the Coriolis online densitometer measures density, the measuring tube continuously vibrates at a certain resonance frequency. Because the resonance frequency is a function of fluid density, when fluids of different densities are filled with the vibrating tube, the vibration frequency will also change. Therefore, measuring the frequency change of the vibrating tube completes the density measurement, and the density has a unique linear relationship with the vibration frequency of the vibrating tube. This method is accurate and reliable in measurement, and has a wide measurement range suitable for various fluid density. The Kodensimeter has very small pressure loss and has inherent advantages in measuring the density of viscous fluids such as mud.

    In the current production process, there are more and more requirements for density measurement. The accuracy of density measurement directly affects the quality of the production process. Traditional density measurement uses the principle of buoyancy or radioactivity, and its measurement accuracy can meet the requirements, but the buoyancy density meter has certain limitations in practical applications. The density meter based on the radioactivity principle requires very high maintenance of the system and has certain damage to the human body, so it is only used in some special occasions. In the actual application process, we believe that the density measurement of the mass density meter based on the Koishi force principle can well meet the requirements of actual production and completely overcome the shortcomings of the buoyancy density meter.
