Abstract
Generally, liquid level sensors are used to determine the liquid mass or head in tank filling, holding, and propellant utilization systems for rocket vehicles, and also In storage Inventory and research applications. The latter two applications are so varied that they will not be discussed further. Tank filling and holding to a predetermined liquid mass require a flow control system that is maintained by a liquid level sensor. The sensor may be a continuous-reading type or a rake of point sensors located in the vicinity of the required level Propellant utilization systems control the relative flows of the liquid pro-pellants so that, ideally, no propellant is left over at burnout. A liquid level sensing and control system monitors the liquid mass in each tank during outflow and corrects the relative propellant flows to obtain the desired result. The level sensor again may be either a continuous sensor or a rake of point sensors.
