Micropilot NMR84 Function and system design Measuring principle Micropilot is a directional level radar, operating based on the "Frequency-Modulated Continuous Wave" principle (FMCW). The radar emits a precise crystal-oscillated, continuously varying frequency wave from the antenna. The wave is reflected off the product surface and received again by the radar system. D R A0023768 1 R D FMCW principle: Emission and reflection of the continuous wave.
Micropilot NMR84 Integration of tank sensors In addition to measuring the level, the device can also be used for the integration of tank sensors into tank inventory systems. All measured and calculated values can be displayed at the built-in display. Via a field communication protocol, they can be transferred to an inventory control system.
Micropilot NMR84 Measuring system • From single tank level measurement to the largest oil refinery applications, Endress+Hauser tank gauging devices are an integral part of tank farm management solutions. A wide variety of data output protocols are available for seamless integration into many commonly used systems. • A primary example is Tankvision from Endress+Hauser. Tankvision is a scalable system offering local tank management for multiple loops via Modbus or V1 protocols.

Micropilot NMR84 Application packages Advanced tank measurement methods The device software provides the following tank measurement methods: • Direct level measurement → 35 • Hybrid tank measurement system (HTMS) → 36 • Hydrostatic tank shell correction (HyTD) → 37 • Thermal tank shell correction (CTSh) → 37 Direct level measurement If no advanced tank measurement methods have been selected, level and temperature are measured directly.
Micropilot NMR84 Hybrid tank measurement system (HTMS) HTMS uses level and pressure measurements to calculate the contents of the tank and (optionally) the density of the medium. HTMS measuring modes Measuring mode Installation example HTMS + P1 Measured variables Calculated variables Density of the • Level • Bottom pressure (at position medium D1) 1 mode should be used in atmospheric (i.e.
Micropilot NMR84 Hydrostatic tank shell correction (HyTD) Δx The hydrostatic tank shell correction can be used to compensate for vertical movement of the Gauge Reference Height due to bulging of the tank shell caused by the hydrostatic pressure exerted by the liquid stored in the tank. The compensation is based on a linear approximation obtained from manual hand dips at several levels distributed over the full range of the tank.
