Continuous Liquid Level Measurements with Time-Domain Reflectometry
This presentation shows how a time-domain reflectometer [1–4] provides a simple yet accurate method for making liquid level measurements of cryogenic fluids. Measurement of cryogenic liquid levels in storage vessels has generally been performed with discrete sensors arranged in a ladder configuration. The accuracy of this technique is determined by the spacing of the sensors and their response time.
