Our Ultrasonic Flow Sensors

Precision, Reliability, and Customization for Every Application.

TH series Pulsatile Flow Sensors / Flow Meters

The TH series pulsatile flow rate measurement sensors/flow meters are designed specifically for heart valve, cardiovascular and hemodynamics research.

With the ±3% flow rate measurement accuracy, TH series pulsatile flow rate measurement sensors/flow meters can effectively capture the pulsation characteristics of high-velocity liquids within the test flow path.

Product Features

High Accuracy: ±3%

The flow rate measurement accuracy is essential for applications requiring stringent quality control and process optimization.

PC Software Support

View, monitor, and export real-time flow rate and cumulative volume data seamlessly via intuitive PC software.

Bi-Directional Flow Measurement

It can measure in both directions, calculate the volume of the fluid, and has the function of bubble detection.

Advanced Waveform Analysis

Generate detailed hemodynamic pulsation waveforms and overlay multiple measurement graphs for in-depth comparative analysis.

No Blockages

Designed to operate without blockage or dead zones, enables smoother fluid flow and reduces potential system strain.

Fast Response Time

Features a rapid response time, making it ideal for accurately analyzing pulsating and dynamic flow profiles.

Case in Medical

Extracorporeal Circulation Systems

Extracorporeal Membrane Oxygenation (ECMO), often referred to as an artificial heart-lung machine, is an emergency medical technology used to support or completely replace the function of the heart and/or lungs. In high-risk cardiac procedures like Transcatheter Aortic Valve Replacement (TAVR), as well as in the resuscitation of Intensive Care Unit (ICU) patients suffering from severe respiratory or circulatory failure, ECMO serves as the ultimate line of defense for life.
