Function and system design

100%

Micropilot FMR51, FMR52

Measuring principle

The Micropilot is a "downward-looking" measuring system, operating based on the time-of-flight method (ToF). It measures the distance from the reference point (process connection) to the product surface. Radar impulses are emitted by an antenna, reflected off the product surface and received again by the radar system.

A0017871

 1 Setup parameters of the Micropilot

R Reference point of the measurement (lower edge of the flange or threaded connection) E Empty calibration ( = zero) F Full calibration (= span) D Measured distance L Level (L = E - D)

Input

The reflected radar impulses are received by the antenna and transmitted into the electronics. A microprocessor evaluates the signal and identifies the level echo caused by the reflection of the radar impulse at the product surface. The unambiguous signal identification is accomplished by the PulseMaster® eXact software together with the Multi-echo tracking algorithms, based on many years of experience with time-of-flight technology.

The distance D to the product surface is proportional to the time of flight t of the impulse:

D = c · t/2,

with c being the speed of light.

Based on the known empty distance E, the level L is calculated:

L = E – D

The reference point R of the measurement is located at the process connection. For details see the dimensional drawing:

• FMR51: →  67

• FMR52: →  73 The Micropilot is equipped with functions to suppress interference echoes. The user can activate

these functions. Together with the multi-echo tracking algorithms they ensure that interference echoes (i.e. from edges and weld seams) are not interpreted as level echo.

8 Endress+Hauser

Micropilot FMR51, FMR52

Output

The Micropilot is commissioned by entering an empty distance "E" (=zero), a full distance "F" (=span) and application parameters which automatically adapt the instrument to the process conditions. For models with a current output, the factory adjustment for zero point "E" and span "F" is 4 mA and 20 mA. For digital outputs and the display module, the factory adjustment for zero point "E" and span "F" is 0 % and 100 %.

A linearization with max. 32 points, based on a table entered either manually or semi-automatically, can be activated locally or remotely. This function provides a measurement in engineering units and a linear output signal for spheres, horizontal cylindrical tanks and vessels with conical outlet.

Input

Micropilot FMR51, FMR52

Measured variable

The measured variable is the distance between the reference point and the product surface.

The level is calculated from this distance, taking into account the empty distance "E" entered by the user.

If required, the level can be converted into other variables (volume, mass) by means of a linearization (up to 32 points).

Measuring range Maximum measuring range

Device Maximum measuring range

FMR51 - standard version 40 m (131 ft)

FMR51 - with "Advanced dynamics" application package 70 m (230 ft)

FMR52 - standard version 40 m (131 ft)

FMR52 - with "Advanced dynamics" application package 60 m (197 ft)

Usable measuring range

The usable measuring range depends on the size of the antenna, the reflectivity of the medium, the mounting location and eventual interference reflections.

The following tables describe the groups of media as well as the achievable measuring range as a function of application and media group. If the dielectric constant of a medium is unknown, it is recommended to assume media group B to ensure a reliable measurement.

Media groups

Media groups DC (εr) Example

A 1.4 to 1.9 non-conducting liquids, e.g. liquefied gas

B 1.9 to 4 non-conducting liquids, e.g. benzene, oil, toluene, …

C 4 to 10 e.g. concentrated acids, organic solvents, esters, aniline, alcohol, acetone, …

D > 10 conducting liquids, e.g. aqueous solutions, dilute acids and alkalis

1) Treat Ammonia NH3 as a medium of group A.

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)

The DI block takes a discrete input value (e.g. indication of an level limit), and makes it available to other function blocks at its output.

This block is used to transfer analog data from the bus into the device

This block is used to transfer discrete data from the bus to the device.

PID Block The PID block serves as

proportional-integralderivative controller and is used almost universally to do closed-loopcontrol in the field including cascade and feedforward.

Arithmetic Block

Signal Characterizer Block

Input Selector Block

Integrator Block

Analog Alarm Block

This block is designed to permit simple use of popular measurement math functions. The user does not have to know how to write equations. The math algorithm is selected by name, chosen by the user for the function to be done.

The signal characterizer block has two sections, each with an output that is a non-linear function of the respective input. The non-linear function is determined by a single look-up table with 21 arbitrary x-y pairs.

The input selector block provides selection of up to four inputs and generates an output based on the configured action. This block normally receives its inputs from AI blocks. The block performs maximum, minimum, middle, average and ‘first good’ signal selection.

The Integrator Function Block integrates a variable as a function of the time or accumulates the counts from a Pulse Input block. The block may be used as a totalizer that counts up until reset or as a batch totalizer that has a setpoint, where the integrated or accumulated value is compared to pre-trip and trip settings, generating discrete signals when these settings are reached.

CAUTION

To ensure electrical safety:

Do not disconnect the protective connection.

‣

Disconnect the supply voltage before disconnecting the protective earth.

‣

Connect protective earth to the internal ground terminal (3) before connecting the supply voltage. If necessary, connect the potential matching line to the external ground terminal.

In order to ensure electromagnetic compatibility (EMC): Do not only ground the device via the protective earth conductor of the supply cable. Instead, the functional grounding must also be connected to the process connection (flange or threaded connection) or to the external ground terminal.

An easily accessible power switch must be installed in the proximity of the device. The power switch must be marked as a disconnector for the device (IEC/EN61010).

Connection examples for the switch output

For HART devices, the switch output is available as an option. See product structure, feature 20: "Power Supply, Output", option B: "2-wire; 4-20 mA HART, switch output"

Devices with PROFIBUS PA and FOUNDATION Fieldbus always have a switch output.
