Systems and methods for measurement of fluid delivery

A test system for measuring a volume of fluid dispensed by a fluid infusion device, comprising:

• a test housing that includes an inlet and an internal channel, the inlet to be coupled to the fluid infusion device to receive the volume of fluid, and the internal channel in fluid communication with the inlet;
• a plurality of input electrodes coupled to the internal channel to be in fluid communication with the volume of fluid;
• a plurality of output electrodes coupled to the internal channel to be in fluid communication with the volume of fluid, the plurality of output electrodes spaced apart from a respective one of the plurality of input electrodes;
• a power source configured to apply, to at least one of the plurality of input electrodes, a voltage to the respective one of the plurality of input electrodes;
• and
• a controller configured to:
• determine whether the respective one of the plurality of input electrodes and the respective at least one of the plurality of output electrodes have been activated based on the voltage potential created between the respective one of the plurality of input electrodes and the respective at least one of the plurality of output electrodes causing the volume of fluid in the internal channel to conduct current between the respective one of the plurality of input electrodes and the respective at least one of the plurality of output electrodes;
• and
• determine a measurement of the volume of fluid dispensed by the fluid infusion device based on whether the respective one of the plurality of input electrodes and the respective at least one of the plurality of output electrodes have been activated.
