Intelligent Tanks Tuning Fork Density Meter Small Blind Area NYDE - CR Insertion
Working Principle of Tuning Fork Density Meter
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 a piezoelectric device fixed at one end of the bottom of the fork body. The oscillation frequency is detected by a secondary piezoelectric device fixed to the other end of the fork, and then the signal is amplified by the circuit on the top. The liquid density is closely related to the vibration frequency when the measured liquid flows. When the measured liquid density changes, the vibration frequency when the liquid flows also changes. Through the equation, the density of the measured liquid can be accurately calculated
Design Features of Tuning Fork Density Meter
◎ suitable for density measurement of tanks, pipes, flowing or static medium. Suitable for medium with high temperature, low temperature and high viscosity containing impurities.
◎ The electronic conversion device based on microprocessor integrates signal processing, calculation and diagnosis functions.
◎ Continuous online measurement of liquid density and temperature, high accuracy, more safe and reliable, can be directly used for production process control
◎It can communicate directly with PC through RS485 interface, and users can directly configure online contacts, diagnose faults and record data
◎While measuring density and temperature, basic density, concentration percentage, mass percentage, volume percentage and other parameters can be calculated
◎excellent overpressure protection structure, superior temperature stability, all welded sealing, solid and reliable design.
◎it is easy to install and use, and the data can be displayed by inserting liquid.
◎Simplify maintenance without regular cleaning
◎Calibration no need standard reference source, laboratory calibration,without process interruption
◎Intrinsically safe type can be used in hazardous sites, and sanitary type can be installed in food production sites
