As a non-native speaker I'm looking for the right term for a technical application/product that dispenses or doses a viscous liquid, i.e. the device will "output" a specific amount of "stuff".
However, dosing/dose/dosage appear to be "medical" to me, also maybe describing a ratio of components (like controlling the amount / rate of medicine/drug added to an IV drip).
On the other hand, dispenser more seems to be "outputting" or making available already discrete "entities", e.g. a tissue dispenser.
I'm lacking knowledge of more elaborate uses of those words and appreciate any comments.
