Why NMR81 Is More Than a Level Transmitter

The Micropilot NMR81 is an 80 GHz intelligent tank gauge designed for high-accuracy liquid level measurement in storage and process applications. It supports inventory management, loss control, operational safety and—when the correct approved configuration is selected—custody-transfer duties. Typical media include fuels, chemicals and alcohols.

Senior Engineer’s Warning: Six Decisions That Change the Instrument

1. Accuracy and legal metrology: ordinary inventory measurement and custody-transfer service are not interchangeable. Define the required approval and calibration range.

2. Antenna and measuring range: 2, 3 and 4 inch antenna choices, the medium dielectric constant and internal reflections affect usable range.

3. Tank pressure and temperature: provide design and operating values, not only normal conditions.

4. Communication architecture: confirm V1, Modbus RS-485, HART and the intended Tankvision, DCS or inventory system interface.

5. Integrated measurements: specify whether water bottom, average temperature and pressure transmitters must be integrated.

6. Hazardous-area and safety approvals: confirm area classification, SIL duty, overfill function and destination-country requirements before ordering.

Never shorten this to “NMR81” on a purchase request. The suffix can define antenna, process connection, housing, power, communication, accuracy, approval, I/O and application packages. Copy the complete code exactly from the approved material list, quotation or nameplate.

Applications Where NMR81 Earns Its Place

• Oil and fuel storage terminals requiring high-accuracy inventory control

• Chemical and alcohol storage tanks

• Atmospheric and pressurized tank applications within the selected configuration

• Tank farms integrating radar, temperature, pressure and water-bottom data

• Loss-control and custody-transfer projects with defined metrology requirements

Frequently Asked Questions

Is every NMR81 automatically approved for custody transfer?
No. Accuracy, legal-metrology approval and calibration range depend on the selected configuration and destination requirements.

How far can NMR81 measure?
Usable range depends on antenna size, dielectric constant, approval and installation. Provide the actual tank and medium data for selection.

Can I request a quotation using only “NMR81”?
No firm quotation should rely on the family name alone. Send the complete code, quantity and project requirements.
