For terminal operators, refinery engineers, environmental compliance managers, and EPC instrumentation teams who need precise, continuous level and interface measurement in aboveground and underground storage tanks, the MCG 8150B Rigid Magnetostrictive Level Probe offers a powerful solution. This probe delivers 0.001 inch resolution, dual-level detection, and integrated temperature averaging in a rigid 316 stainless-steel housing built for long-term reliability. The MCG 8150B provides drift-free performance, meets EPA requirements for underground storage tanks (USTs), and delivers custody-grade data for petroleum, chemical, and process applications.
Magnetostrictive technology provides true digital-grade measurement with 0.001 inch resolution, ensuring highly accurate inventory and eliminating recalibration drift.
The rigid probe tube is built from corrosion-resistant 316 stainless steel, guaranteeing long-term durability in fuels, chemicals, and wastewater service.
Simultaneously measures product level and interface level (e.g., oil/water), providing essential data for contamination detection and tank integrity assurance.
Features five embedded RTDs to calculate an accurate average product temperature, crucial for API 2540 volume correction.
Meets EPA UST Requirements and is UL-listed, simplifying environmental monitoring and reducing liability risk.
Performs both continuous level measurement and overfill/low-level protection in a single device, reducing the need for separate hardware.
Adapts easily to 2″, 3″, or 4″ risers, with flanged options available for quick and cost-effective drop-in replacements.

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.
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.
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.
