TrueFlow Technology - Operational benefits

Calibration-free ultrasound technology

The original ultrasonic flow measurement is highly accurate in almost all flow ranges, independent of gas composition, pressure, temperature and humidity and does not require calibration during its lifetime.

Effortless infection control for a hygenic solution

The sensor is never in direct contact of the patient‘s breath. ndd TrueFlow is a hygienic and resistance-free solution.

Minimal risk for cross-contamination

ndd products are small with easy-to-wipe surfaces. There are no fragile sensor parts to be cleaned. And testing elements in touch with patient breath are single-use and exchangeable.

Top choice for clinical research studies

ndd EasyOne products have been utilized in multiple, high-visibility clinical research studies, including COPDGene, Multicenter AIDS Cohort Study (MACS), and the BOLD and PLATINO studies.

Ease of use for efficient workflows

There are no moving parts, no codes to enter, and no testing elements to calibrate.

Measurement performance at low flows

ndd’s ultrasonic flow sensor technology provides accurate performance at low flows. Its high durability, low measurement variability, and high repeatability make TrueFlow a superior measurement technology.
