Description

Description

Application

The Micropilot NMR81 is designed for precise custody transfer and inventory management, featuring NMi and PTB approvals and complying with OIML R85 and API 3.1B standards. It is ideal for free space measurement applications up to 70 meters in height. The innovative 80 GHz drip-off lens antenna generates a highly focused 3° beam angle, effectively avoiding any obstacles near the tank wall.

Free Space Measurement: 80 GHz drip-off lens antenna provides enhanced beam focusing for measuring distances up to 70 meters, even with nozzles positioned close to the tank wall.
Process Connections: Flanged connections
Temperature Range: -40 to +170°C (-40 to +338°F)
Pressure Range: From vacuum to +16 bar (vacuum to +232 psi)
Maximum Measuring Range: 70 meters (230 feet)
Measurement Accuracy: ±0.5 mm (±0.02 inches)
Transmitting Frequency: 80 GHz
Certifications: Global explosion protection, custody transfer, overfill prevention (WHG), SIL compliance

Benefits

High Safety Standards: Both hardware and software are developed in accordance with IEC 61508 standards up to SIL3 (in homogeneous redundancy), ensuring a high level of safety.
Exceptional Accuracy: Provides reliable measurements with an accuracy of up to ±0.5 mm (±0.02 inches).
Compliance with Global Standards: Developed to meet international metrology standards such as OIML R85 and API MPMS, with local certifications like NMi and PTB for custody transfer applications.
Easy Integration and Operation: Streamlined installation and seamless operation with major DCS systems through open protocol support.
Advanced 80 GHz Technology: Narrow beam angle for precise targeting, minimizing interference from tank walls and nearby obstructions.
