Critical Technical Advantages
-
Profile-Independent Measurement: Because the acoustic waveguide principle measures the physical properties of the fluid (sound velocity and temperature) directly at the probe head, the measurement is unaffected by flow profiles, turbulence, or gas bubbles in the surrounding pipe or vessel.
-
Direct In Situ Analysis: The Teqwave I eliminates the lag time and safety risks associated with manual sampling. By providing continuous data directly from the heart of the process, it allows for immediate adjustments to mixing ratios or chemical dosing.
-
Multivariable Analysis: The device captures multiple parameters simultaneously—including concentration, sound velocity, and temperature. This consolidated data stream provides a comprehensive view of product quality from a single insertion point.
-
Flexible Insertion Lengths: With probe lengths of 180 mm or 500 mm, the device can be positioned precisely within a vessel or large pipe to ensure the sensor head is always submerged in the representative process medium.
-
Robust and Maintenance-Free: The solid-state design of the waveguide sensor has no moving parts or sensitive optical windows that can foul or break. This ensures long-term stability and a very low cost of ownership compared to refractive index or titration-based systems.
-
Advanced Data Logging: To meet strict regulatory and quality audit requirements, the integrated data logger stores process values for up to 7.5 years, ensuring that batch quality can be verified long after production is complete.
