Online digital display vibrating Density Meter/concentration meter
Online digital display vibrating Density Meter/concentration meter
The plug-in density meter adopts plug-in installation and is widely used in pipelines, open tanks and closed tanks to detect the density of the medium in the tank. The density of the fluid directly depends on the vibration frequency received by the tuning fork in the sensor inserted into the medium. The built-in temperature sensor of the sensor provides temperature compensation for it.

Scope of application: The plug-in density meter can perform real-time online density detection. It can be used for process control of products with density as the basic parameter or quality control with solid percentage or concentration percentage as a reference. Typical industries include petrochemical industry, wine industry, food industry, pharmaceutical industry and mineral processing (such as clay, carbonate, silicate, etc.), which are specifically used in the interface detection and mixing of multi-product pipelines in the above industries The density detection, the end-point monitoring of the reactor, the interface detection of the separator. The sensor works based on the principle of component vibration, and the component part is the tuning fork part immersed in the measured liquid. The tuning fork part induces vibration through an internal piezoelectric device fixed at the bottom end of the fork body. The oscillation frequency is detected by a secondary piezoelectric device fixed at the other end of the fork body, and then the signal is amplified by the circuit on the top. The density of the liquid is closely related to the vibration frequency when the measured liquid flows. When the density of the measured liquid changes, the vibration frequency when the liquid flows also changes. Through the following equation, the density of the measured liquid can be accurately calculated.
