Tank Gauging
Application
Micropilot NMR8 Series intelligent tank gauges are designed for high accuracy liquid
level measurement in storage and process applications. They fulfill the exacting
demands of tank inventory management, inventory control, custody transfer, loss
control, total cost saving, and safe operation.
Typical areas of application
• Precise level measurement of oil (fuels), chemicals, and alcohol in free space
• Tank mounted intelligence makes NMR8x ideal for single or multi-task
installations, measuring the liquid level and integrating a wide range of tank
sensor measurement functions including: Liquid level, Water level, Temperature
and Pressure.

Micropilot NMR81
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.

1
FMCW principle: Emission and reflection of the continuous wave.
Reference point of the measurement
Distance between R and the product surface
The frequency of this wave is precisely modulated in the form of a sawtooth signal between two limit
frequencies f1 and f2:
f2
Δf
Δt
f1
A0023771
2
FMCW principle: Results of the frequency modulation
Emitted signal
Received signal
Thus, at any given time the frequencies of the emitted and the received signal differ by
Δf = k Δt
where Δt is the transit time and k is the known slope of the frequency modulation.
Δt, on the other hand, is determined by the distance D between the reference point R and the
product surface:
D = (c Δt) / 2
where c is the speed of propagation of the wave.
In summary, D can be calculated from the measured frequency shift Δf. D is then used to calculate
the contents of the tank.

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.

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. Accumulated data is
available to DCS and other plant management systems via a Host Link.

Measured variable
The measured variable is the distance between a reference point (mounting flange) and a reflective
surface (e.g. product surface).
Maximum measuring range
The maximum measuring range depends on the dielectric constant εr of the measured medium and
on the size of the antenna:

Feature 100 of the product structure
For devices with Weight+Measure approval: Maximum measuring range: 30 m (97 ft)
For dielectric constants (DC values) of many media commonly used in various industries refer
to:
• the Endress+Hauser DC manual (CP01076F)
• the Endress+Hauser "DC Values App" (available for Android and iOS)
For devices with Weight+Measure approval (option LK or LL of ordering feature 590
"Additional Approval"): Maximum measuring range: 0.8 to 30 m (2.6 to 97 ft)
The actual usable measuring range depends on additional criteria like the mounting location or
possible interference reflections.

Micropilot NMR8x that are certified for Custody Transfer applications are calibrated on a
certified production rig. The production rig reference standard is a laser tracker with an
absolute accuracy of ±0.016 mm and a resolution of 0.0001 mm. Calibration is performed at 10
equally-spaced measuring points over the full measuring range.
The Maximum Permissible Error (MPE) is ±0.5 mm (±¹⁄₃₂ in) for Maximum performance
models, and ±1 mm (±¹⁄₁₆ in) for Custody transfer models. The resultant Factory Calibration
Certificate is included in the scope of delivery along with the respective type approval
certificate.

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.
A0023774
15
Movement Δx of the Gauge Reference Height due to the bulging of the tank shell caused by hydrostatic
pressure
Thermal tank shell correction (CTSh)
The thermal tank shell correction can be used to compensate for vertical movement of the Gauge
Reference Height due to temperature effects on the tank shell or stilling well. The calculation is
based on the thermal expansion coefficients of steel and on insulation factors for both the dry and
wetted part of the tank shell.
This correction is recommended for any tank gauge operating at conditions deviating
considerably from the conditions during calibration and for extremely high tanks. For
refrigerated, cryogenic and heated applications this correction is highly recommended.
