With the rapid development of biopharmaceutical technology, the demands for detecting and quantifying biologics are increasing.

Chromatographic filtration is a commonly used analytical method in biopharmaceuticals, where flow control plays a crucial role in achieving efficient analysis.

In recent years, ultrasonic flow sensors have gradually become the focal point of chromatographic filtration process in the biopharmaceutical industry due to the advantages of high precision, high stability, no pollution, no need movingc parts.

Fact about Chromatographic Filtration

Chromatographic filtration is an important separation and quantification technology in biopharmaceuticals, widely used in the purification, detection, and quantitative analysis of biomolecules process.

Chromatographic filtration refers to the separation and determination of multi-component mixtures by utilizing the differences in the physical and chemical properties of each component in the mixture.

The mechanism of chromatography can be divided into adsorption chromatography, distribution chromatography, ion exchange chromatography, gel filtration chromatography, and so on.

In the process of chromatography, controlling the flow rate significantly influences the efficiency of the chromatographic column, the separation effect of the samples, and the overall results of the experiment.

Traditional flow controllers, such as rotary pumps and piston pumps, have achieved some success in practical applications.

However, their complex structure and limited lifespan make it challenging to meet the demand for high-precision and high-stability flow control in the field of biopharmaceuticals.

Therefore, the adoption of a new type of flow control technology has become an urgent need.

The Working Principle of Ultrasonic Flow Sensor

Ultrasonic flow sensors, as a new type of flow measurement equipment, have garnered widespread attention in recent years for their applications in biopharmaceutical chromatography filtration.

Ultrasonic flow sensors utilize ultrasonic propagation characteristics in the fluid medium to measure the flow. Their working principle is based on tTransit-time difference technology.

When the ultrasonic wave propagates downstream, its propagation time decreases due to the fluid flow; conversely, in the upstream, its propagation time increases due to the fluid flow. Ultrasonic flow sensors or ultrasonic flow meters measure the ultrasonic propagation time in both downstream and upstream to calculate fluid flow rates and cumulative volume.

The main components of the ultrasonic flow sensor include the transmitter, receiver, signal processor, and optional display . The transmitter is responsible for generating ultrasonic signals, the receiver is responsible for receiving the ultrasonic signals during the propagation process, the signal processor processes and calculates the received signals, and finally, the display shows the measurement results.

This non-invasive measurement method not only reduces interference with the fluid but also achieves high accuracy and stability.
