-Overview-
This product is an online tuning fork density meter (also known as an online tuning fork concentration meter), designed for real-time, continuous monitoring of liquid media in industrial processes. It operates based on the vibration principle of a tuning fork, measuring density by analyzing changes in the vibration frequency of the liquid within the liquid, and incorporates temperature compensation to improve accuracy. Based on the density value, the instrument can further convert and output various concentration-related parameters, such as percentage concentration, Baumé degree, and saccharification, meeting diverse process monitoring needs.
This instrument is suitable for various harsh operating conditions and is widely used in industries such as petrochemicals, chemicals, pharmaceuticals, food and beverage, environmental protection, and battery electrolytes. It can reliably measure various acids, alkalis, and salt solutions, alcohols, syrups, wastewater slurries, and other media. Its core advantage lies in its ability to be directly installed on pipelines or tanks, enabling online quality control and process optimization during production, effectively replacing traditional manual sampling and testing, and improving efficiency and consistency.
The product offers multiple process connection methods and wetted material options to adapt to different installation environments and media characteristics. It features user-friendly on-site commissioning and calibration functions, supports fine-tuning of measured values and pure water calibration, ensuring measurement accuracy and stability during long-term operation, making it a reliable choice for achieving precise measurement and control in process industries.
