Features

High-Resolution Accuracy

Magnetostrictive sensing provides ±0.001-inch repeatability, delivering custody-grade measurement stability without drift for precise inventory, reconciliation, and interface monitoring.

Corrosion-Resistant Build

Rigid 316 stainless-steel construction withstands fuels, chemicals, and wastewater exposure, ensuring dependable service life and minimal mechanical degradation in harsh environments.

Dual-Level Detection

Two floats allow simultaneous measurement of product and interface levels, improving contamination detection and supporting BS&W or water-bottom monitoring.

Five-Point Temperature Averaging

Embedded RTDs capture accurate average product temperature, ensuring proper API 2540 volume correction and supporting regulatory and quality requirements.

EPA UST Compliance

Certified for underground storage tank applications, providing verified environmental monitoring performance and reducing liability associated with regulated fuel storage.

Integrated Point Switch

Built-in point-switch capability enables overfill or high-level alarms without extra hardware, simplifying installation and improving safety assurance.

Applications

  • Custody Transfer: Provides high-resolution, drift-free level data that supports accurate billing, reconciled inventories, and custody-transfer reporting for petroleum and chemical operations.
  • Interface Detection: Dual-float measurement identifies oil-water or product-product interfaces, preventing contamination events and enabling timely tank maintenance actions.
  • Environmental Compliance: EPA-listed design supports underground storage monitoring requirements, reducing compliance risk for fuel terminals and regulated facilities.
  • Retrofit Installations: Standard 2″, 3″, and 4″ openings and Tankway connectivity allow drop-in replacement for legacy probes without system rewiring.
  • Overfill Protection: Integrated point-switch mode adds high-level alarm capability, reducing the number of devices required for safe tank-farm operation.

How does the MCG 8150B ensure accuracy for custody transfer?

−

The MCG 8150B uses magnetostrictive technology to deliver a resolution of 0.001inch, which is significantly more precise than typical mechanical or ultrasonic devices. This high resolution, combined with five internal RTDs for temperature-compensated volume correction, ensures the data is custody-transfer grade and auditable per API standards.

Is the probe approved for use in underground storage tanks (USTs)?

+

Yes. The MCG 8150B is UL listed and EPA compliant for use in underground storage tanks. This certification is essential for meeting environmental monitoring and compliance requirements for fuel and hazardous liquid storage.

How does the dual-level measurement function?

+

The probe utilizes two separate magnetic floats: one is weighted to float on the top surface of the primary product (e.g., gasoline) and one is weighted to float on the interface between the product and any denser liquid (e.g. water/ BS&W). The probe tracks the position of both floats simultaneously, providing continuous, separate readings for product level and interface level.
