Orifice Meter Product Offerings

TMCO Orifice Fittings

TMCO – Sureshot Dual Chamber and Single Chamber
TMCO orifice fittings are known for precision, durability, and ease of maintenance. Our Sureshot series offers both dual and single chamber designs to meet varying pressure, flow, and application requirements. Features include:

Dual-chamber design for enhanced measurement accuracy under fluctuating flow conditions
Single-chamber options optimized for simplicity and cost-effectiveness
Robust construction to withstand extreme environmental and process conditions
Compatibility with standard orifice plates and accessories

TMCO fittings are ideal for both midstream transmission pipelines and upstream production facilities, delivering consistent and verifiable flow measurement.

Daniel Orifice Fittings

Daniel – Daniel Senior and Daniel Simplex
Daniel orifice meters are widely recognized for precision, reliability, and API-aligned measurement performance. Circle B offers two primary Daniel fitting types:

Daniel Senior: Engineered for high-pressure and high-flow applications, the Senior line ensures minimal turbulence and highly accurate differential pressure readings.
Daniel Simplex: Designed for straightforward installations where ease of maintenance and reliability are key, Simplex fittings deliver consistent measurement without compromising compliance.

Both options integrate seamlessly with field calibration practices, flow computers, and MVS systems to support custody transfer and process monitoring.

Canalta Orifice Fittings

Canalta – Dual Chamber and Single Chamber
Canalta orifice meters provide flexible, rugged solutions for pipeline and process applications. Key features include:

Dual-chamber designs for enhanced flow stability in variable conditions
Single-chamber options for simpler installations or lower-flow applications
Built with ASTM-certified materials and designed for long-term service
Compatible with standard orifice plates and differential pressure measurement instruments

Canalta fittings are ideal for operations seeking durable, reliable measurement in both onshore and remote pipeline environments.

Integration with Skid and Piping Systems

Circle B does more than provide orifice fittings. We integrate orifice meters into complete measurement systems including:

Skid Fabrication: Orifice meters can be installed on custom skids designed for rapid deployment and operational flexibility. Skid integration includes properly sized piping, supports, and instrumentation to ensure accurate flow readings.
Piping Fabrication: Our team ensures orifice meter connections comply with API 1104 and ASME B31.3/B31.8 standards, including certified welding and NDE verification.
Flow Computers & Control Systems: Orifice meters are paired with flow computers and MVS solutions for real-time measurement, verification, and data logging.

By integrating orifice meters with fabricated skids and piping, Circle B delivers turnkey solutions that are ready for immediate installation and operation.

Compliance and Standards

Orifice meters installed and maintained by Circle B are fully compliant with industry standards:
- API 14.3 & 14.3.1: Orifice meter design, installation, and calibration guidelines
- AGA Report No. 3 & No. 9: Flow measurement and differential pressure calculation standards
- ASTM Materials: All fittings and piping components use ASTM-certified materials for strength and longevity
- ASME Codes: Compliance with B31.3, B31.8, and B31.4 piping standards ensures structural integrity and operational safety
Our adherence to these standards ensures measurement accuracy, defensibility for custody transfer, and operational safety across all installations.

Field Services and Lifecycle Support

Circle B provides ongoing field support for orifice meters, including:
Calibration & Verification: Regular calibration per API and AGA guidelines to maintain accuracy

Meter Tube Maintenance: Cleaning, inspection, and replacement services to prevent performance degradation

Flow Computer Troubleshooting: Integration and support for MVS systems to validate measurement data

Gas Sampling: Spot sampling and laboratory support to confirm gas composition and energy content

This full lifecycle approach ensures that your orifice meter system continues to perform reliably and within tolerance for years to come.

Applications Across the Energy Industry

Orifice meters are essential for a variety of operational contexts:

Upstream Production: Wellhead measurement, gas lift lines, and production monitoring
Midstream Transmission: Pipeline custody transfer, gas quality verification, and pressure monitoring
Processing Facilities: Gas conditioning, dehydration, and metering stations
Remote or Harsh Environments: Skid-mounted orifice meters designed for reliability in extreme conditions

Circle B tailors each orifice meter installation to the operational environment, ensuring accurate measurement regardless of pressure, temperature, or flow variability.
