Attitude compensating indicator

摘要

An indicator for measuring the liquid content of a container comprises an attitude compensating sensor including at least two variable resistor assemblies disposed within the container. The resistor assemblies are located at opposite ends of the container and are electrically connected to each other in series. Each resistor assembly comprises a resistor disposed within a housing and in communication with a movable wall of said housing located near its lower end. The housing resides in proximity to the bottom wall of the container and registers with the external ambient through an opening provided in one wall thereof. The total resistance developed by the sensor comprises the sum of the resistances of the individual resistors, and remains constant for a particular quantity of liquid regardless of the distribution of the liquid within the container.
