Oil Density Meter Inline
Working Principle
The tuning fork of the density meter for oil is excited by acoustic waves, leaving it to vibrate at its natural resonant frequency. Its vibration frequency is direct correlated with the density of liquids surrounding it. When the medium flows through the fork, the change of resonance frequency is caused by the change of medium quality.
Product Features
● Wide concentration measurement range 0-99% and high accuracy ±0.2%;
● Ideal for harsh conditions for temperature compensation -30 ~120 °C;
● Available anti-corrosion materials for wetted parts (Stainless steel, titanium alloy, Hastelloy alloy, PTFE, ceramic;
● Robust construction to withstand harsh conditions like high temperatures, pressures and corrosive environments;
● Fast response enables real-time density measurements for process control and quality assurance.

Product Advantages
● Simple installation;
● Plug and play;
● Maintenance-free for no moving parts;
Applications
Some production lines or industrial plants could benefit from the inline oil density sensor:
● Petroleum refineries for oil density measurement in crude oil fractionation towers and finished gasoline/diesel conveying pipelines to ensure accurate distillation fraction control and meet national petroleum product density standards;
● Automobile manufacturing plants for oil density monitoring in engine oil circulation systems and gearbox oil storage tanks to detect early oil degradation (e.g., oxidation, impurity mixing) and protect key transmission components;
● Marine transportation industry for oil density detection in ship main engine fuel tanks and lubricating oil supply lines to guarantee fuel combustion efficiency and avoid equipment wear caused by abnormal oil density;
● Edible oil processing enterprises for oil density measurement in soybean oil refining tanks and finished oil filling stations to ensure oil purity (preventing adulteration) and comply with food safety density limits for edible oils;
● Lubricating oil production factories for oil density monitoring in lubricant blending tanks and high-temperature grease processing lines to control product viscosity matching and meet equipment-specific lubrication performance requirements;
● Aerospace maintenance centers for oil density detection in aircraft fuel refueling pipelines and engine slide oil circulation systems to ensure fuel density adapts to high-altitude low-temperature conditions and guarantee engine stable operation.
