Product introduction
Insertion-type Design
The insertion-type density (concentration) meter is installed by direct insertion, making it widely applicable for media density measurement in pipelines, open tanks, and closed containers. The fluid density is directly determined by the vibration frequency of the tuning fork immersed in the medium. A built-in temperature sensor provides temperature compensation.
Application Scope
The insertion-type density (concentration) meter performs real-time online density measurements. It is suitable for process control where density is the key parameter or for quality control based on solid content percentage or concentration percentage. Typical industries include:
Petrochemical
Brewing
Food processing
Pharmaceuticals
Mineral processing (e.g., clay, carbonate, silicate, etc.)
Specific applications include:
Interface detection in multi-product pipelines
Density measurement of stirred mixtures
Endpoint monitoring in reaction vessels
Interface detection in separators
The sensor operates based on a vibrating element principle. The sensing part is the immersed tuning fork. Vibration is excited by a piezoelectric device fixed at one end of the fork, while vibration frequency is detected by a secondary piezoelectric device at the other end. The circuit at the top amplifies the signal.
The vibration frequency varies with the density of the liquid. Thus, the liquid density can be accurately calculated using the following formula:
D= K0+K1T+K2T2
Where:
D = Uncalibrated density of the measured medium (kg/m³)
T = Vibration period (μs)
K0, K1, K2 = Calibration constants
