Non-intrusive density meters are instruments used to measure the density or concentration of a substance without making direct contact with the material being measured.
The term “non-invasive” originally comes from the medical field, where it refers to procedures that do not physically harm or penetrate the body. In industrial applications, it describes methods that do not require physical contact or modification of the object being measured.
Conventional density meters typically require taking a physical sample, placing it in a container, or inserting a sensor into a pipe or tank. Non-intrusive models, on the other hand, use technologies such as radiation, ultrasonic waves, or U-tube sensors to perform measurements externally - eliminating the need to cut pipes or stop production lines.
These meters are widely adopted across industries like chemical processing, food and beverage, energy, and environmental monitoring, thanks to their ability to improve safety, streamline processes, and support automation.
Non-intrusive density meters are used across a range of industries to meet operational challenges and environmental requirements without interfering with ongoing processes.
In chemical plants, non-intrusive density meters are used to monitor chemical concentrations in real time. Ultrasonic sensors are placed outside the piping to continuously track liquid density and concentration. This helps optimize quality control and reduce costs by precisely managing dilution ratios and mixing levels. Because there’s no direct contact - even with corrosive substances - these systems also enhance safety and reduce maintenance demands.
These meters are also widely used in food and beverage manufacturing. Inline sensors can measure Brix (sugar content) and alcohol concentration in products like juice or beer in real time. Integrated with automated control systems, they help maintain consistent product quality and ensure efficient use of raw materials.
In the medical field, bone densitometers fall under the category of non-intrusive density meters. Using ultrasonic pulse velocity and attenuation, these devices can safely and quickly assess bone density without the need for invasive procedures. Different models are available to suit various parts of the body.
