Abstract: The volumetric flow meter for gases with magnetic fluid is built
using a sensing unit (without moving solid mechanical components but exploiting
the properties of magnetic fluids) and an electronic measuring system. The
sensing unit consists of two sensors, one for differential pressure in gases
(equipped with a laminar flow-measuring tube) and another for acceleration or
inclination angle. Starting from some technical characteristics (of these
sensing units) obtained by a numerical simulation method (or by an analytical
one), the paper presents the possibility of using this kind of transducers in a
N+1 flow meters network for gases. Every N flow meters of
closed range are supervised by another flow meter of higher range. This
structure can warn (by software) about any problem (e.g. gases leakage) in the
network.
