For over 50 years, we habe been developing a complete range of instrumentation products oriented towards the measurement and control of fluids.

Flow sensors

Flow measurement with primary elements called differential pressure elements / flowmeters manufactured according to ISO 5167, ISO / TR 15377, ISO / TR 11583, ASME MFC-3M, ASME MFC-14M, ASME MFC-12M, ISO 9300, ASME PTC 19.5 , ... standards (orifice plates, venturis, nozzles, pitot tubes, v-cone meters, wedge meters and other special flow meters).
Our devices comply with the European PED Directive 2014/68/EU.

Temperature sensors

Temperature measurement with devices such as thermometers, thermocouples, probes and other special sensors thermowells.

Restriction orifices

Flow limitation and pressure regulation devices also called restriction orifices (single, multi-hole and multi-stage restriction orifices).

Piping & instrumentation accessories

Piping accessories such as flanges, condensation pots, flow straighteners, flow conditioners, flow indicators, spades & spacers...
Instrumentation accessories such as 2, 3 or 5 way manifolds, differential pressure transmitters, instrumentation cabinets...

Deltafluid operates in numerous industries such as oil & gas, chemicals & petrochemicals, energy including renewable and nuclear energy, metallurgy, paper manufacturing, agri-food, water and smoke treatment, aeronautics... with major references in each of these sectors.
