How to Choose the Right Flow Measurement Product
Choosing the right product depends on your service conditions, installation constraints, and allowable pressure loss. Here’s a simple way to narrow it down:
- Need low permanent pressure loss? Consider venturi tubes.
- Need a standards-based, cost-effective DP primary element? Consider orifice plates or paddle-type orifice plates.
- High velocity or severe service? Consider flow nozzles.
- Need a complete meter run? Explore meter tubes and straightening vanes.
- Protect instruments and improve reliability? Add strainers, condensate chambers, and bleed rings.
Need custom materials, non-standard dimensions, or special machining? We support special builds through custom machine work.
