Selection Guide
Steam Meters
Steam metering for industrial food production and thermal processes. Steam's thermal density and ease of transport make it critical for moving high amounts of energy throughout a site. Although there are many benefits to steam, there are also many challenges with its production and distribution — condensate return and the on-demand capacity requirements from the lack of storage provide their own set of challenges.
Why it matters
Steam is essential for industrial processes but presents unique measurement challenges due to its volatility, limited flow turndown ratios, and condensate management requirements. Steam metering is also critical for Scope 1 carbon emission management since steam boilers are often the largest natural gas consumers at a facility. Steam metering helps track consumption accurately, manage energy costs, optimize system performance, and identify leaks or inefficiencies within steam production, transport, and point of use.
Key selection factors
- Steam type: saturated vs. superheated — not all meters handle both
- Pressure, temperature, and flow rate range
- Peak and minimum expected flows (turndown ratio is critical — limited hardware capabilities)
- Pipe size and available straight pipe runs upstream/downstream
- Steam quality — wet or dirty steam affects certain meter types
- Distribution piping is typically oversized for minimal pressure drop — this can produce flow velocities below minimum meter thresholds, potentially requiring pipe necking sections
Meter types
Vortex Steam Meters
Most common choice. Suitable for most saturated and superheated steam applications. Reliable, accurate, and low-maintenance.
Turbine Steam Meters
Effective for clean steam with lower flow rates. Fast response for real-time monitoring but contains moving parts requiring regular maintenance.
Differential Pressure (Orifice Plate)
Cost-effective and industry-proven with established installation practices. No moving parts. Best for stable, predictable flows.
Coriolis Steam Meters
Superior accuracy (±0.1–0.5%) with direct mass flow measurement. Measures mass flow, density, and temperature simultaneously. Ideal for critical or high-value steam applications.
Ultrasonic Steam Meters
Non-intrusive, causing no pressure loss. Highly effective across a broad flow range. Resistant to harsh operating conditions. High cost — best for high-value applications only.
Installation guidelines
- Steam meter installations should be handled by qualified professionals due to complexity and safety hazards
- Ensure straight pipe runs upstream and downstream to reduce turbulence
- Install strainers or filters upstream to protect the meter from debris
- Maintain correct orientation (horizontal or vertical) as specified by manufacturer
- Implement proper insulation to maintain temperature consistency
- Distribution piping may be oversized — install pipe sections to neck down the pipe and increase flow velocity across the meter
- Consider steam quality: wet or dirty steam affects most meter types
💡 Pro tip
Steam distribution piping is typically oversized to achieve minimal pressure drops, but this can contribute to flow velocities below the minimum needed to register on metering products. It may be necessary to install new pipe sections to neck down the pipe while increasing flow velocity across the metering device.
Recommended approach
Vortex with multivariable pressure/temperature compensation for most campus and process loops; Coriolis for critical or high-value steam; DP/orifice where pressure class and budget demand it.
