Why Choose Wafer Over Flanged Configuration
Space Savings:
- 60-70% shorter face-to-face length
- Fits in tight retrofits where flanged meters don't
- Critical for skid-mounted equipment with limited space
Weight Reduction:
- 50-70% lighter than flanged equivalents
- Easier handling during installation
- Reduced structural support requirements
Cost Efficiency:
- 30-40% lower equipment cost
- Faster installation (45-60 minutes vs. 2-3 hours)
- Lower shipping costs due to reduced weight
Installation Simplicity:
- Uses existing pipe flanges and longer bolts
- No separate meter flanges to purchase
- Quick removal for inspection or service
Performance:
- Identical measurement accuracy to flanged
- Same rangeability and turndown
- Equal temperature and pressure ratings
When to Choose Wafer:
- Space-constrained installations
- Retrofit applications with existing flanges
- Multiple measurement points requiring cost optimization
- Skid-mounted or modular equipment
- Any application where flanged meter size/weight is problematic
When to Choose Flanged:
- Very high pressure applications (>4.0 MPa)
- Extremely large pipe sizes (>DN300)
- Situations requiring integral flow straighteners
- Locations with severe vibration (flanged body provides damping)
Proven Performance Across Steam, Gas, and Liquid Applications
Compact wafer design delivers accurate measurement in space-constrained industrial installations
Steam & Thermal Energy Monitoring
The definitive solution for boiler houses and power plants. It manages saturated and superheated steam at temperatures up to 450°C, providing the mass-flow data required to optimize boiler efficiency and reduce fuel costs.
Industrial Compressed Air Monitoring
Identify expensive leaks and balance air compressor loads across the factory. The meter’s wide range ratio captures both high-velocity production air and low-velocity nighttime leaks to slash electricity overhead.
Chemical & Petrochemical Processing
Safely measures Nitrogen, Argon, and volatile fuel gases. Constructed from 316L stainless steel with Exd II CT2-T5 explosion-proof ratings, it ensures reliability and safety in hazardous chemical environments.
Natural Gas & LPG Management
Provides standardized volume measurement for internal cost allocation and commercial gas monitoring. Its non-volatile memory ensures every cubic meter is accounted for, even in the event of a facility power outage.
HVAC & District Heating
Ideal for large-scale heat distribution and water monitoring in commercial complexes. The compact wafer design allows for easy installation in crowded mechanical rooms and utility tunnels where space is a premium.
