Time domain reflectometry liquid level sensing for launch vehicles
Abstract:
A system for determining a fluid level includes a front end and a measurement probe. The measurement probe receives a pulse from the front end and returns a partially reflected pulse and a fully reflected pulse to the front end. The partially reflected pulse is evaluated to determine a liquid level within a tank that includes the measurement probe. The measurement probe includes a conductive trace configuration to provide a time delay to prevent pulse build up.
