Stainless Steel Custody Transfer Level Probe

MPX-R API 18.2

Certified Accuracy For Oil Storage and Transfer

The MPX API 18.2 Custody Transfer Magnetostrictive Level Probes are designed for precise level and temperature measurements in oil storage and transfer applications, with API 18.2 certification. The MPX-R model features a 1″ stainless steel stem and include digital temperature sensors and robust floats that resist fouling for optimal performance in high turbidity environments.

The MPX API 18.2 probes provide Modbus RTU output via RS-485, offering highly accurate and repeatable level readings and configurable volume outputs. Ideal for hazardous locations, they offer multiple stem and float material options to ensure chemical compatibility. Remote monitoring capability enables easy management of alarms, sensor configuration, and user permissions.

  • Hazardous Location Certifications: Class 1 Division 1 Groups C & D, Class 1 Zone 1, Class 1 Zone 2
  • Accurate and Repeatable: Highly accurate and repeatable readings
  • Flexible Communication: RS-485 (Modbus RTU) output
  • Durable and Reliable: Rugged and reliable, lengths up to 31.5 feet (9.60 m)
  • Dual Measurement Capability: Dual level (interface) measurement
  • Tank Volume/Level Calculation: Tank volume/level, strapping table

What is the MPX API 18.2 Custody Transfer Magnetostrictive Level Probe used for?

The MPX API 18.2 probes are designed for precise level and temperature measurement in oil storage and transfer applications. They provide highly accurate and repeatable readings, making them ideal for custody transfer and lease tank monitoring.

API 18.2 certification ensures the probes meet industry standards for custody transfer measurements in lease automatic custody transfer (LACT) units and oil storage applications. This guarantees compliance, reliability, and accuracy in critical measurement processes.

  • MPX-R: Features a 1″ 316L stainless steel stem, suitable for general oil storage applications.
  • MPX-T: Uses a 1″ titanium stem, offering enhanced chemical compatibility for more demanding environments.

Yes, the probes support both level and configurable volume outputs, allowing users to tailor the data to their specific application needs.

Integration is straightforward via RS-485 Modbus RTU, a widely used industrial communication protocol. Configuration instructions and Modbus registers are provided in the product documentation.
