High precision UTDR measurements by sonic velocity compensation with reference transducer.

Sensors (Basel, Switzerland)

Stade S, Kallioinen M, Mänttäri M, Tuuva T.
PMID: 24991939
Sensors (Basel). 2014 Jul 02;14(7):11682-90. doi: 10.3390/s140711682.

An ultrasonic sensor design with sonic velocity compensation is developed to improve the accuracy of distance measurement in membrane modules. High accuracy real-time distance measurements are needed in membrane fouling and compaction studies. The benefits of the sonic velocity...
