Abstract

A method for determining a volume of fluid dispensed into a test housing includes creating an electrical potential across at least one input electrode of a plurality of input electrodes and at least one output electrode of a plurality of output electrodes. The input electrodes and the output electrodes are each coupled to the test housing. The method includes receiving at least one signal from the at least one output electrode based on the fluid dispensed into the test housing. The method includes calculating the volume of fluid dispensed into the test housing based on the at least one signal received from the at least one output electrode, a dimension associated with an internal channel defined within the test housing, and a distance between two input electrodes of the plurality of input electrodes.

Dependent claims

A processor-implemented method comprising:

processing a signal indicative of activation of an output electrode of a plurality of output electrodes positioned along a dimension of a fluid channel, each output electrode of the plurality of output electrodes corresponding to a respective input electrode of a plurality of input electrodes positioned along the dimension of the fluid channel, the activation of the output electrode being caused by electrical current conducted between the output electrode and a corresponding input electrode through fluid that accumulates along the dimension of the fluid channel as the fluid is dispensed into the fluid channel;
identifying which output electrode, of the plurality of output electrodes, was activated to cause generation of the signal;
calculating a volume of the fluid dispensed into the fluid channel based on a relative position of the identified output electrode along the dimension of the fluid channel.
