Vibrating Fork Density Meter

Short Description:

The vibration density meter with microprocessor-based electronic conversion unit aggregates signal processing, calculation and diagnostic functions. It’s designed to detect the medium density in storage tanks and pipelines for interface detection, stirred mixture and monitoring of the end point of the reactor. The vibrating fork type density meter enables direct communication with PLC/DCS system through the 4-20 mA signal and RS485 interface.

    Working Principle

    The vibration type density meter is designed on the basis of the vibration principle of components. Two teeth of the tuning fork vibrates for a piezoelectric crystal located at the root of the teeth. The frequency of vibration is measured by another piezoelectric crystal. The vibration type liquid density meter stabilizes on the natural resonance frequency. The resonance frequency changes with medium quality when the medium flows through the tuning fork.
