Sažetak
The current assortment of sensing devices for measuring rate of fluid flow covers a wide range of requirements
related to normal operation conditions. In the area of the low and very low fluid flow devices the offered assortment
is being diminished sharply. Availability of the devices is very limited and costly. The aim of the article is to design
a methodology for constructing a sensor for measuring the low liquid flows and the experimental verification of
design. The gas flow meter is based on the calometric measurement principle so that the flow rate it assessed taking
into account the known transferred amount of heat to the fluid flow and the temperature differences of the medium
before and after electric coil of Thomas cylinder determined by thermocouples.
