Exotic Materials for Differential Flow Meters: Choosing the Right Alloy for Extreme Environments
Differential pressure flow meters such as orifice plates and venturi tubes are proven technologies across industrial and municipal applications. In harsh environments, however, standard stainless steel is not always enough.
Exotic alloys like Monel, Hastelloy, Titanium, and Tantalum deliver extended performance, safety, and reliability under extreme conditions.
Why Consider Exotic Materials?
Key Benefits:
- Superior resistance to corrosion and erosion
- Longer service life with reduced downtime
- Reliable accuracy in aggressive or variable media
- Cryogenic compatibility (Monel and Titanium)
- Increased safety in high-risk applications
These benefits help lower lifecycle costs while ensuring dependable performance where it matters most.
Special Service Materials at a Glance
Monel
Marine service, LNG transfer, desalination. Resistant to seawater and hydrofluoric acid.
Hastelloy
Chlor-alkali, sulfur recovery, acid streams. Excellent resistance to pitting and cracking.
Titanium
Aerospace, subsea, high-purity processing. Lightweight and highly resistant to chlorides.
Tantalum
Pharmaceutical and semiconductor applications. Unmatched chemical inertness for ultra-corrosive environments.
Typical Applications
- LNG and energy: cryogenic venturi tubes (Titanium, Monel)
- Petrochemicals: HF acid service (Hastelloy)
- Pharmaceuticals: ultra-pure acid handling (Tantalum)
- Aerospace: cryogenic propellant systems (Titanium)
