Instrumentation & fluid regulation

Our job is to provide you expertise and know-how in studying and manufacturing systems for measurement and regulation of your industrial fluids.

Customized products & solutions

For more than 50 years, Deltafluid has been designing, manufacturing and distributing solutions for flow measurement, temperature measurement, flow control and pressure regulation for industries in the Oil & Gas, Chemical & Petrochemicals, Energy, Food, Iron & Steel, Aeronautics ... with a wealth of experience across all these areas of activity.

The scope of our range allows us to meet the diversity of your needs and your applications.

Every product or solution is designed and manufactured to your specification and in accordance with current standards and the relevant construction codes.

Expertise & advice 

Attentive to your needs, Deltafluid's experts will discuss your requirements with you and provide a technical and cost-effective solution that is perfectly suited to your application.  

Flow measurement

Concerning flow measurement devices, they provide you with information such as :

• the principle of differential pressure flow measurement,
• flow measurement methods and technologies, 
• the most suitable solutions for liquids, gases or steam,
• the features and strengths of each solution,
• the measurement accuracy, the measurement of volumetric or mass flow rate...

to the selection of the equipment needed to ensure the performance and safety of your installation. 

We also have the SIZEWELL tool, developed by Deltafluid, available to help you select the flow measurement devices best suited to your needs.

Temperature measurement

When it comes to temperature measurement devices, our experts can offer you a range of solutions: 

• mechanical expansion or bimetallic devices,
• resistance temperature probe or thermocouple probe, with the corresponding temperature range and specification, 
• the complete sensor solution including the probe, head, terminal block or transmitter, fittings and drilled or mechanically welded thermowells... 

Restriction orifices

As for restriction orifices, that is, the calibrated orifice which, when fitted to a pipe, allows you to acheive the desired flow rate or pressure - they will be able to advise you on:

• the operating principle,
• specific phenomena such as cavitation, critical flow or ou choked flow / choking cavitation, and the phenomenon of flashing - see FAQs
• select the appropriate component to prevent premature wear of the pipe and plate, and to avoid excessive noise and vibration levels,
• the various types of restriction orifices including those with multiple orifices to reduce noise level (conditioning restriction orifice) and those with multiple plates arranged in series when the desired pressure drop cannot be acheived with a single plate (multi-stage restriction orifices)

Pipe and instrumentation accessories

Finally, we also offer a full range of piping and instrumentation accessories to round out our product range and provide you with a comprehensive solution.

Machining & welded assemblies

Our mechanical workshop covers an area of over 1300 sqm with an extensive range of machinery of more than 30 turning, milling, drilling, boring equipment to manufacture machined parts.  

Deltafluid also specialises in the manufacture of welded assemblies intended to equip systems or processes designed by our cutomers.

A new workshop covering covering more than 1000 sqm is currently under construction. It is due to open in the first half of 2026 and will enable us to expand our production capacity and provide us with larger aseembly, testing and storage areas. 

At Deltafluid, we handle every stage of the manufacturing process from sourcing raw materials (round bars, sheet metals, tubes...) through to delivery : precision machining, welding, testing and inspection, cleaning, surface treatment, and the assembly of complete units... to best meet all your needs and suit all your applications.
