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 FMCW principle: Emission and reflection of the continuous wave.
R Reference point of the measurement
D 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:
f
t
1
2
f2
f1
Δt Δf
A0023771
2 FMCW principle: Results of the frequency modulation
1 Emitted signal
2 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.

Installation
Installation conditions Conditions for the stilling well
• Metal (no enamel coating)
• Constant diameter (no rectangular stilling wells)
• Weld seam as smooth as possible
• For best radar propagation behavior it is recommended to have holes instead of slots. If slots can
not be avoided, they should be as thin and short as possible.
• Maximum gap between antenna/horn and wall of the stilling well: 5 mm (0.2 in).
• At any transition (e.g. when using a ball valve or mending pipe segments) gaps must not exceed
1 mm (0.04 in).
• The stilling well must be smooth on the inside. Average roughness ≤ 6.3 µm (0.248 µin)
• Length and number of the holes do not affect the measurement. The hole diameter (deburred) can
be 1/7 of the well diameter, but should not exceed 25 mm (1 in).
• An increase of the pipe diameter is possible if the minimum lengths according to the following

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.

Dual seal according to
ANSI/ISA 12.27.01
The devices have been designed according to ANSI/ISA 12.27.01 as dual seal devices, allowing the
user to waive the use and save the cost of installing external secondary process seals in the conduit
as required by the process sealing sections of ANSI/NFPA 70 (NEC) and CSA 22.1 (CEC). These
instruments comply with the North-American installation practice and provide a very safe and cost-
saving installation for pressurized applications with hazardous fluids.

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.

HTMS uses level and pressure measurements to calculate the contents of the tank and (optionally)
the density of the medium.

Hydrostatic tank shell correction (HyTD)
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
16 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.
