What Deltafluid does
Deltafluid is a French designer and manufacturer of industrial flow measurement, temperature measurement, and pressure regulation equipment, headquartered in Lacq, Nouvelle-Aquitaine (RD 817, Chemin Les Augas, 64170 Lacq). The company builds primary flow elements — orifice plates, venturi tubes, nozzles, pitot tubes, cone meters, wedge meters, and compact multi-hole flowmeters — together with thermometers, thermocouples, PT100 probes, thermowells, multi-stage restriction orifices (up to 13 stages and 210 barg capability), and a range of piping accessories (manifolds, spectacle blinds, special flanges, condensation pots, instrumentation valves). All products are custom-manufactured per customer specifications in compliance with ISO 5167, ASME, RCC-M/RCC-MRx, and PED 2014/68/UE.
The company earns revenue primarily from one-time equipment sales plus professional services (fluid mechanics engineering, feasibility studies, simulations, precision machining, welding, NDT). Pricing is quote-based, tied to materials, complexity, certifications, and lead time. Commercial reach operates through direct enterprise field sales supported by a regional partner network in Belgium (ELNEO), UAE (FALCOR), Kuwait, and Cameroon (SPARK INNOVATION); more than 50% of turnover is generated from export markets. Named customers include EDF, TotalEnergies, Air Liquide, Technip Energies, GE, ExxonMobil, ArcelorMittal, Arkema, Dalkia, Veolia, ENI, Saipem, and Kuwait Petroleum Corporation.
In May 2025 Deltafluid was acquired by Alfeor Group (backed by Otium), becoming the group's fifth acquisition in under 18 months within a roll-up targeting €250M turnover by 2030. The company is differentiated by ISO 19443 nuclear certification (Nov 2023), EDF-UTO qualification (Sept 2020), KPC qualification (Oct 2024), and the proprietary SIZEWELL web-based sizing tool. A 1,000 sqm building extension is under construction for 2026, nearly doubling existing capacity, alongside investment in a new Chevalier CNC milling lathe.

Deltafluid competitors and assessment
Company assessmentRegional players
- Forbes Marshall: Indian manufacturer of flow, temperature, and pressure measurement instrumentation with strong presence in South Asia and a growing international footprint. Closely comparable product portfolio to Deltafluid across steam, process, and boiler applications, though primarily regional.
Broad incumbents
- Endress+Hauser: Family-owned German leader in industrial process measurement, including vortex, DP, Coriolis, and ultrasonic flowmeters plus temperature instrumentation. Serves the same chemical, oil & gas, nuclear, and hydrogen verticals as Deltafluid, with broader portfolio and global service network.
- Emerson Electric (Rosemount): Emerson's Rosemount division is the global market leader in DP flow measurement (orifice plates, manifolds, primary elements) and pressure/temperature instrumentation, making it the most direct incumbent peer to Deltafluid across process industries. Comparable product scope, though with global scale and integrated transmitters that Deltafluid doesn't produce.
- CIRCOR International (Weamco): Manufacturer of flow control products including restriction orifices and critical-service valves for O&G, power, and chemical industries. Directly comparable to Deltafluid's restriction orifice product line, with broader portfolio and global presence.
- ABB Measurement & Analytics: ABB's instrumentation business supplies DP flow elements, pressure/temperature transmitters, and analyzers to oil & gas, chemical, and power customers globally. Overlaps with Deltafluid on primary elements and process measurement, with a much broader automation portfolio.
- Yokogawa Electric: Japanese process automation and instrumentation company with a broad DP and vortex flow portfolio, pressure transmitters, and temperature sensors widely deployed in O&G, petrochemical, and power — the same core verticals Deltafluid serves. Comparable application footprint with much larger scale.
Emerging players
- SciCam (Pulsar Measurement): Specialist in flow and level measurement for water, wastewater, and industrial process applications. Adjacent to Deltafluid in measurement instrumentation but with limited overlap in nuclear and hydrogen niches.
Direct peers
- McCrometer (a subsidiary of Hach): US-based flow measurement specialist with cone (V-Cone) and other differential pressure flowmeters, serving oil & gas, water, and process industries. Direct competitor to Deltafluid's V-Cone and wedge meter product lines with comparable technology positioning.
- KROHNE Group: German flow measurement specialist with strong presence in process industries, including differential pressure primary elements, variable area meters, and dedicated nuclear and hydrogen offerings. Closest direct competitor to Deltafluid in scope of primary flow elements and vertical focus.
- Hoffer Flow Controls: US manufacturer of flow measurement equipment including turbine meters and DP-based systems, with applications across oil & gas, chemical, and nuclear. Comparable to Deltafluid in flow element engineering focus and in serving safety-critical industries.
