Dråpetellerdoserør

Dråpetellerdoserør is a term used in fluid handling and automated dosing to describe a system that combines a droplet counter with a dosing tube. The concept refers to equipment designed to quantify and dispense precise amounts of liquid using discrete droplets, enabling controlled dosing with traceability.

A typical dråpetellerdoserør setup includes a droplet counter and a dosing tube connected to a reservoir or pump. The counter, which may employ optical, capacitive, or electrostatic sensing, records individual droplets as they pass a sensing point. A control system uses the counted droplets to regulate the dosing mechanism, such as a valve or syringe plunger, to reach a target dose.

Operation generally involves setting a desired volume or number of droplets. As droplets are generated and counted, the dosing component adjusts in real time to achieve the specified total. This approach offers fine-grained dosing and a record of delivered volumes, which can be important for quality control and reproducibility.

Applications for this type of system include laboratory microfluidics for reagent mixing, pharmaceutical manufacturing for precise dosing, agricultural spraying where droplet counts relate to delivered volume, and coating or printing processes that require discrete droplet deposition.

Origin and terminology are Scandinavian in character, with “dråpeteller” meaning droplet counter and “doserør” meaning dosing tube. The term may appear in technical literature and vendor documentation within Norwegian or broader Nordic contexts.
