In Tank Density Meter
Working Principle
The in-process tank level density meter uses a piezoelectric tuning fork as its core sensing component. This tuning fork is driven by a piezoelectric element to vibrate stably at its inherent natural frequency during operation. When the liquid in the reaction vessel or tank (such as in mixing, distillation, or crystallization processes) comes into contact with the tuning fork, the liquid’s density directly affects the total mass of the tuning fork assembly. This change in total mass triggers a corresponding shift in the tuning fork’s vibration frequency. The meter then converts this frequency change into a measurable signal, thereby calculating the liquid’s density and concentration accurately.
Product Features
• High-Precision Tuning Fork Density Meter: Advanced vibrating fork technology for accurate online density measurement with 0.003 g/ml accuracy.
• Wide Measurement Range: Covers 0-2 g/ml density, supporting high-viscosity fluids up to 2000 cP, ensuring reliable performance in pipelines, tanks, and storage vessels.
• Integrated Temperature Compensation: Built-in sensor for real-time adjustments across -30°C to 120°C operating range.
• 4-20mA Analog Output with Display: Seamless integration with PLC systems, featuring a 4-digit LED display for density, concentration, and temperature readout.
• Explosion-Proof and Durable Design: ExdIIBT6 certified for hazardous environments, constructed from 316 stainless steel (optional Hastelloy).
• Flexible Installation Options: Direct insertion for horizontal/vertical pipelines or flange mounting in tanks.
• Continuous Real-Time Monitoring: Provides uninterrupted online density and concentration data, eliminating lab analysis needs.
• Certifications for Quality Assurance: Customizable CE, FCC and RoHs certificates, ensuring safety and reliability in pharmaceutical, beverage, and oil industries.
• User-Friendly Calibration: Simple water calibration and menu-driven interface for fine-tuning.
