Abstract
A flow measuring device, comprising a container for receiving a flow of liquid, a plurality of optical sensors associated with the container, each of the plurality of optical sensors producing an output signal dependent upon the presence of liquid reaching a level in the container associated with each optical sensor, means for modifying the output signal in accordance with at least one predetermined temperature compensation factor, and means for calculating a flow rate from the time at which the liquid traverses between two levels in the container.
