Abstract

The present technology relates to a volumetric measurement device and various methods for operation of the device. The device comprises at least one accelerometer for detecting the angle of tilt/tip of a container. The device also comprises at least one fluid property processor capable of providing at least one fluidic property value of a fluid, a flow-rate processor capable of continuously calculating the present flow rate of the fluid when poured from the container, and a volume processor capable of continuously calculating the present volume of the fluid within the container. The flow-rate processor calculates the rate of flow of the fluid poured from the container based on the angle of tilt/tip of the apparatus, the at least one fluid property value, and the present volume of fluid within the container.
