What is a Non-intrusive Density Metersr?
Non-intrusive Density Meters are devices that measure density or concentration without directly touching the object being measured.
The term “non-invasive” was originally a medical term meaning “testing without harming the body,” and in the industrial and measurement fields, it refers to “a method that allows measurement without physical contact or processing of the object.
With conventional density meters, it is necessary to take a sample and place it in a container for measurement, or to insert a sensor into a pipe or tank. Non-intrusive Density Meters, on the other hand, use radiation, ultrasonic, or U-tube sensors to measure density from outside a pipe or container, eliminating the need to cut pipes or stop production lines during measurement.
Non-intrusive Density Meters are being used in a variety of fields, including chemical, food, energy, and environmental, because of their advantages in terms of improved worker safety, process efficiency, and automation of measurement.
Uses of Non-intrusive Density Meters
Non-intrusive Density Meters are used in a variety of applications to meet the challenges and environmental conditions of different industries.
1. Industrial applications
Non-intrusive Density Meters are used for real-time monitoring of chemical concentrations in chemical plants. Ultrasonic waves are emitted from outside the piping to continuously measure the density and concentration of the internal liquid. This contributes to quality control and cost optimization by determining the dilution state and mixing ratio of chemical solutions. In addition, since even corrosive chemicals can be measured without direct contact, the system is extremely safe and reduces the need for maintenance and inspections.
2. Food production
Non-intrusive Density Meters are also used in food and beverage production lines. Inline density meters can measure the sugar content (Brix value) and alcohol concentration of products such as juice or beer in real time. By being closely related to the automatic control of the production process, it is possible to supply products of consistent quality and improve the efficiency of raw material use.
3. Mmedical field
In the medical field, bone densitometers fall into the category of Non-intrusive Density Meters. It measures density from the sound velocity and attenuation of ultrasonic pulses, and its great advantage is that it can be done safely in a short time. Products suitable for each part of the body to be examined are available.
