Technical Information

Micropilot M FMR250

Level-Radar

Smart Transmitter for continuous and non-contact level

measurement in solids.

Cost-effective 4 to 20 mA 2-wire technology.

Application

The Micropilot M performs continuous, non-contact

level measurement especially in powdery to granular

bulk solids. Additionally it can be used in liquids as well.

Dust, filling noises, temperature layers and gas

stratification do not affect measurement.

Typical areas of application are:

• Level measurement in tall silos with extremely dusty

bulk solids e.g. cement, raw meal or animal feed.

• Applications with high temperature requirements up

to 200 °C (392 °F), e.g. clinker or fly ash.

• Applications with highly abrasive bulk solids e.g.

ferrite.

The FMR250 with DN80 or DN100 horn antenna for all

standard applications, particularly also for small nozzle

sizes.

The FMR250 with DN200 parabolic antenna offers high

beam focussing of 4° and is thus ideal for applications

with many installations.

Micropilot M FMR250

Endress+Hauser 3

Function and system design

Measuring principle The Micropilot is a "downward-looking" measuring system, operating based on the time-of-flight method. 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.

L00-FMR250xx-15-00-00-en-001

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® software, 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

Refer to the above figure for the reference point for "E".

The Micropilot is equipped with functions to suppress interference echoes. The user can activate these

functions. They ensure that interference echoes (i.e. from internals and struts) are not interpreted as level echo.

Output

The Micropilot is commissioned by entering an empty distance E (=zero), a full distance F (=span) and an

application parameter. The application parameter automatically adapts the instrument to the process

conditions. The data points “E” and “F” correspond with 4mA and 20mA for instruments with current output.

They correspond with 0 % and 100 % for digital outputs and the display module.

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.

System integration via Fieldgate

Vendor Managed Inventory

By using Fieldgates to interrogate tank or silo levels remotely, suppliers of raw materials can provide their

regular customers with information about the current supplies at any time and, for example, account for them

in their own production planning. For their part, the Fieldgates monitor the configured level limits and, if

required, automatically activate the next supply. The spectrum of options here ranges from a simple purchasing

requisition via e-mail through to fully automatic order administration by coupling XML data into the planning

systems on both sides.

Remote maintenance of measuring equipment

Fieldgates not only transfer the current measured values, they also alert the responsible standby personnel, if

required, via e-mail or SMS. In the event of an alarm or also when performing routine checks, service

technicians can diagnose and configure connected HART devices remotely. All that is required for this is the

corresponding HART operating software (e.g. ToF Tool - FieldTool Package, FieldCare, ...) for the connected

device. Fieldgate passes on the information transparently, so that all options for the respective operating

software are available remotely. Some on-site service operations can be avoided by using remote diagnosis and

remote configuration and all others can at least be better planned and prepared.

L00-FXA520xx-14-00-06-en-009

Note!

The number of instruments which can be connected in mutidrop mode can be calculated by the "FieldNetCalc"

program. A description of this program can be found in Technical Information TI 400F (Multidrop Conncector

Input

Measured variable The measured variable is the distance between a reference point (refer to fig. on page 2) and a reflective surface

(i.e. medium surface).

The level is calculated based on the vessel height entered.The level can be converted into other units (volume,

mass) by means of a linearization (32 points).

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 maximum configurable range is 70 m (229 ft) for

Micropilot M FMR250.

Reduction of the max. possible measuring range through:

• Media with poor reflection properties (= small DC). For examples refer to table 1.

• Angle of repose.

• Extremely loose surfaces of bulk solids, e.g. bulk solids with low bulk weight for pneumatic filling.

• Build-up, above all of moist products.

Table 1:

The following table describes the media groups and the dielectric constant εr.

The respective lower group applies for very loose or loosened bulk solids.

Antenna type Application

FMR250-*4*... 3" (DN80)

FMR250-*5*... 4" (DN100)

The FMR250 with 3" (DN80) or 4" (DN100) horn antenna for all standard applications,

particularly also for small nozzle sizes.

To achieve an optimised signal strength it is recommended to use an antenna with as

large as possible diameter.

In small tanks in particular, an antenna extension should not be used wherever possible

to optimize dynamics at close range.

FMR250-*6*... 8"(DN200) The FMR250 with 8" (DN200) parabolic antenna offers high beam focussing of 4° and is

thus ideal for applications with many installations.

Micropilot M FMR250

Measuring conditions • The measuring range begins, where the beam hits the vessel bottom. Particularly with dish bottoms or

conical outlets the level cannot be detected below this point.

The maximum measuring range can be increased in such applications by using a top target positioner

(see Page 16).

• In case of media with a low dielectric constant (groups A and B), the vessel bottom can be visible through

the medium at low levels. In order to guarantee the required accuracy in these cases, it is recommended to

position the zero-point at a distance C = 2" to 6" (50...150 mm) above the vessel bottom (see Fig.).

• In principle it is possible to measure up to the tip of the antenna with FMR250. However, due to

considerations regarding abrasion and build-up, the end of the measuring range should not be chosen any

closer than A=16" (400 mm, see Fig.) to the tip of the antenna.

Integrator Block 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

Operating conditions: Installation

Installation instructions Orientation

• Recommended distance (1) wall – outer edge of

nozzle: ~1/6 of vessel diameter. However, the

device should not, under any circumstances, be

mounted less than 20 cm (8") from the vessel wall.

Note!

If the tank wall is not smooth (corrugated metal,

welding seams, irregularities etc.) the distance from

the wall should be kept as large as possible. If

necessary, use a top target positioner to prevent

interference reflections from the tank wall.

• Not in the centre (3), interference can cause signal

loss.

• Not above the fill stream (4).

• It is recommended to use a weather protection

cover (2) in order to protect the transmitter from

direct sun or rain. Assembly and disassembly is

simply done by means of a tension clamp (see

Accessorieson page 39).

• In extremely dusty applications, the integrated air

purge connection can prevent clogging of the

antenna.

Vessel installations

• Avoid any installations (1), like limit switches,

struts, etc., inside the signal beam (see Beam angle

on Page 17).

• Symmetrical installations (2), i.e. reinforcing rings,

heating coils, etc., can also interfere with the

measurement.

Optimization options

• Antenna size: the bigger the antenna, the smaller

the beam angle, the less interference echoes.

• Mapping: the measurement can be optimized by

means of electronic suppression of interference

echoes.

• Antenna alignment: refer to "Optimum mounting

position"

• In devices with top target positioner, the sensor can

be optimally aimed within the vessel, and/or

interference reflections can be avoided.

The max. angle β is ±15°.

• In particular, sensor alignment serves to:

– prevent interference reflections

– extend the maximum possible measuring range

in conical outlets.

• Metallic screens (3) mounted at a slope spread the

radar signals and can, therefore, reduce

interference echoes.

Measurement in a plastic tank

If the outer wall of the tank is made of a non-conductive material (e.g. GRP), microwaves can also be reflected

off interfering installations outside the signal beam (e.g. metallic pipes (1), ladders (2), grates (3), …). Therefore,

avoid such interfering installations in the signal beam.

L00-FMR250xx-17-00-00-xx-014

Please contact Endress+Hauser for further information.

Beam angle The beam angle is defined as the angle a where the energy density of the radar waves reaches half the value of

the maximum energy density (3dB-width). Microwaves are also emitted outside the signal beam and can be

reflected off interfering installations. Beam diameter W as function of antenna type (beam angle α) and

Cleaning of the antenna The antenna can get contaminated, depending on the application. The emission and reception of microwaves

can eventually be hindered. The degree of contamination leading to an error depends on the medium and the

reflectivity, mainly determined by the dielectric constant εr. If the medium tends to cause contamination and

deposits, cleaning on a regular basis is recommended. Care has to be taken not to damage the antenna in the

process of a mechanical or hose-down cleaning (eventually air purge connection). The material compatibility

has to be considered if cleaning agents are used!

The maximum permitted temperature at the flange should not be exceeded.

Electromagnetic compatibility

(EMC)

• Electromagnetic compatibility to EN 61326 and NAMUR recommendation EMC (NE 21). For details refer

to the declaration of conformity.

• A standard installation cable is sufficient if only the analogue signal is used. Use a screened cable when

Human interface

Operation concept The display of the process value and the configuration of the Micropilot occur locally by means of a large 4-line

alphanumeric display with plain text information. The guided menu system with integrated help texts ensures

a quick and safe commissioning.

To access the display the cover of the electronic compartment may be removed even in hazardous area (IS and

XP).

Remote commissioning, including documentation of the measuring point and in-depth analysis functions, is

supported via the ToF Tool, the graphical operating software for E+H time-of-flight systems.

Display elements Liquid crystal display (LCD):

Four lines with 20 characters each. Display contrast adjustable through key combination.

L00-FMxxxxxx-07-00-00-en-001

The VU331 LCD display can be removed to ease operation by simply pressing the snap-fit (see graphic above).

It is connected to the device by means of a 20" (500 mm) cable.

The following table describes the symbols that appear on the liquid crystal display:
