Microflow sensor modelling

Abstract

Článek se zabývá modelováním velmi mlých průtoků plynů. Jsou vyrobeny modely průtokoměrů v nanoliterech za minutu a ž mikrolitry za minutu. Uvedený průtokoměr nachází uplatnění v biotechnologiích, farmaceuticekém průmyslu apd.

The tiny liquid flows measurement and control within the range nanolitres to mililitres per minute is becoming more and more important for a lot of applications in the science, e.g. analysis, biotechnologies, synthesis (of e.g. pharmaceuticals) and nanotechnology markets. Accompanying demands to flow sensors suited for this low flow range are an extremely small internal volume, the use of fused silica as wetted material for the flow sensor tube (instead of stainless steel), and a modular set-up of the instruments, so they can be easily exchanged and adapted to a new need.
