Pipeline Density Meter
Density Meter in Pipeline
The pipeline density meter utilizes cutting-edge frequency tracking technology for compliance to high requirements in accuracy. It operates on vibration principle to excite a metal tuning fork by signal source of acoustic wave. Then the tuning fork vibrates at the central frequency, which is correlating to density and concentration in correspondence. Therefore, the liquid density could be measured, and temperature compensation can be applied to eliminate system temperature drift.
The concentration can then be calculated based on the relationship between the liquid density and concentration, providing the concentration value at 20°C. This pipeline densitometer is designed for insertion installation, offering a fully integrated "plug-and-play, maintenance-free" solution for density and concentration measurement. It is widely applicable for detecting medium density in pipelines, open tanks, and enclosed containers.
