Flow calculation basics
DP flow is derived from differential pressure, geometry, density and a validated discharge relationship.
TECHNICAL RESOURCES
DP Flow Meter Technical Resources
Use these resources to frame your application, compare primary-element families and prepare the inputs needed for defensible sizing.
Selection methodology
Evaluate turndown, pressure loss, straight runs, media behavior, maintenance and approval needs together.
Standards framework
Apply the correct part and edition of ISO 5167:2022 or the project-specific code.
QUICK SELECTION GUIDE
Match the meter to the dominant constraint
| Application condition | Starting point | Primary reason |
|---|---|---|
| Clean liquid, gas or steam | Standard orifice plate | Standards-based, economical |
| Low pressure-loss priority | Venturi tube | Strong pressure recovery |
| Viscous or solids-bearing media | Wedge flow meter | Open flow passage |
| Large pipe or duct | Averaging Pitot tube | Low loss, insertion format |
| Limited straight-run availability | V-Cone | Center-body flow conditioning |
| Prepaid steam distribution | SmartBalance ProValve® | Integrated metering and control |
This guide is preliminary. Final selection requires complete process and mechanical data.
