3.3 Installation

3.3.1 Mounting kit

In addition to the tool needed for flange mounting, you will require the following tool:

• 4 mm Allen wrench for turning the housing.

3.3.2 Mounting probes

Caution! If there is a risk of electrostatic discharge from the product, then both processconnection and rope must be earthed before the probe is lowered into the silo.

Insert probe

• Uncoil rope and lower it slowly and carefully into the silo.

• Do not kink the rope

• Avoid any backlash, since this mightdamage the probe or the silo fittings.

•

Note!

– Flanges: bolt the flange in positionbefore

inserting the cable into the silo.

– Be sure to use unpainted metal bolts

toensure good electrical contact betweenprobe flange and process flange.

3.3.3 General instructions

Normally use rod or coax probes for liquids. Rope probes are used in liquids for measuring ranges > 4m and with restricted ceiling clearance which does not allow the installation of rigid probes.

Minimum distance B of the probe to the container wall:

The wall clearance can be chosen as desired as long as the probe does not touch the tank wall.

Note!

• There should be no metallic parts or persons moving when installation is made in plastic tanks, also on the outside of the tank at a distance of 300 mm to the probe.

• There should no bridges to the wall created by soiling or highly viscous media.

Mounting location

• Do not mount rod or rope probes in the filling curtain (3).

• Mount rod and rope probes away from the wall (B) at such a distance that, in the event of build-up on the wall, there is still a minimum distance of 100 mm between the probe and the build-up.

• Mount rod and rope probes as far away as possible from installed fittings. "Mapping " must be carried out during commissioning in the event of distances < 300 mm.

• Minimum distance of probe end to the container floor (C): – Rope probe: 150 mm – Rod probe: 50 mm

• When installing outdoors, it is recommended that you use a protective cover (1) see Accessories on → ä 61.

L00-FMP4xxxx-17-00-00-xx-007

Other installations

• Select the mounting location such that the distance to internals (5) (e.g. limit switch, struts) > is 300 mm over the entire length of the probe, also during operation.

• Probe must within the measuring span not touch any internals during operation.

Optimization options

• Interference echo suppression: Measurement can be optimised by electronically tuning out interference echoes.

Type of probe mounting

• When installing in plastic tanks, the nozzle must have at least DN50/2". The appropriate flange must be used as the process connection.

• For nozzles up to 450 mm high, select the length of the centering rod appropriate for the nozzle height when using rope probes.

• Use spring washers (1) (see Figure below). Note! It is recommended to retighten the flange bolts periodically, depending on process temperature and pressure. Recommended torque: 60...100 Nm.

• After mounting, the housing can be turned 350° in order to simplify access to the display and the terminal compartment.

L00-FMP41Cxx-17-0 0-00-en-005

The coupling nut must be tightened using a torque of 5 up to a maximum of 10 Nm when installing the FMP41C in the universal adapter ("Welding boss for adapter 43 mm" → ä 61).

Supporting probes against warping

For WHG or Ex approval: For probe lengths ≥ 3 m a support is required (see figure).

3.3.4 Special instructions

When installing in stirring tanks, observe lateral load of probes. Possibly check whether a noncontact process, ultrasound or radar would not be better suited, above all if the stirrer generates large mechanical loads on the probe.

Installation in horizontal cylindrical and standing tanks

• Use a rod probe for measuring ranges up to 4 m. For anything over this or if there is too free cover space use a rope probe.

• Any distance from wall, as long as occasional contact is prevented.

L00-FMP4xxxx-17-00-00-yy-049

Installation in stilling well or bypass

• Rod and rope probes can also be installed in pipes (stilling well, bypass).

• When installing in metal pipes up to DN 150/ 6", the measuring sensitivity of the device increases such that liquids as of DK 1.4 can be measured.

• Welded joints that protrude up to approx. 5 mm/0.2" inwards do not influence measurement.

3.3.5 Notes on special installation situations

Installation at an angle

• For mechanical reasons, the probe should be installed as vertically as possible.

• Installation with a deviation up to approx. 5° from the vertical axis is permitted for probes up to approx. 1 m in length.

L00-FMP4xxxx-17-00- 00-de-048

0...5

max. 1 m

Fixing rope probe

• The end of the probe needs to be secured if the probe would otherwise touch the silo wall, the cone or another part, or the probe comes closer than 0.5 m to a concrete wall. This is what the internal thread in the probe weight is intended for: – for 4 mm rope: M 14 – for 6 mm rope: M 20

• Preferably use the 6 mm rope probe due to the higher tensile strength when fixing a rope probe.

• The fixing must be either reliably grounded or reliably insulated (see "Accessories" on → ä 64)! If it is not possible to mount the probe weight with a safe earthed connection, it can be secured using an isolated eyelet, which is available as an accessory (see → ä 64).

• In order to prevent an extremely high tensile load and the risk of rope crack, the rope has to be slack. Make the rope longer than the required measuring range such that there is a sag in the middle of the rope that is ≥ 1cm/m (1"/100") of the rope length.

5.1.1 General structure of the operating menu

The operating menu is made up of two levels:

• Function groups (00, 01, 03, …, 0C, 0D): The individual operating options of the instrument are split up roughly into different function groups. The function groups that are available include, e.g.: "basic setup", "safety settings.", "output", "display", etc.

• Functions (001, 002, 003, …, 0D8, 0D9): Each function group consists of one or more functions. The functions perform the actual operation or parameterisation of the instrument. Numerical values can be entered here and parameters can be selected and saved. The available functions of the “basic setup" (00) function group include, e.g.: "tank properties" (002), "medium property" (003), "process cond." (004), "empty calibr." (005), etc.

If, for example, the application of the instrument is to be changed, carry out the following procedure:

1. Select the “basic setup" (00) function group.

2. Select the "tank properties" (002) function (where the existing tank shape is selected).

5.1.2 Identifying the functions

For simple orientation within the function menus, for each function a position is shown on the display.

5.3.3 Factory settings (Reset)

Caution! A reset sets the instrument back to the factory settings. This can lead to an impairment of the measurement. Generally, you should perform a basic setup again following a reset.

A reset is only necessary:

• if the instrument no longer functions

• if the instrument must be moved from one measuring point to another

• if the instrument is being de-installed /put into storage/installed

User input ("reset" (0A3)):

• 333 = customer parameters

333 = reset customer parameters

This reset is recommended whenever an instrument with an unknown 'history' is to be used in an application:

• The Levelflex is reset to the default values.

• The customer specific tank map is not deleted.

• The mapping can also be deleted in the "cust. tank map" (055) function of the "extended

5.4 Display and acknowledging error messages

Type of error

Errors that occur during commissioning or measuring are displayed immediately on the local display. If two or more system or process errors occur, the error with the highest priority is the one shown on the display.

The measuring system distinguishes between two types of error:

• A (Alarm): Instrument goes into a defined state (e.g. MAX 22 mA) Indicated by a constant symbol. (For a description of the codes see → ä 66)

• W (Warning): Instrument continue measuring, error message is displayed. Indicated by a flashing symbol. (For a description of the codes see → ä 66)

• E (Alarm / Warning): Configurable (e.g. loss of echo, level within the safety distance) Indicated by a constant/flashing symbol. (For a description of the codes see → ä 66)

Error messages

Error messages appear as four lines of plain text on the display. In addition, a unique error code is also output. A description of the error codes is given on → ä 66.

•The "diagnostics" (0A) function group can display current errors as well as the last errors that occurred.

• If several current errors occur, use

or S to page through the error messages.

• The last occurring error can be deleted in the "diagnostics" (0A) function group with the function "clear last error" (0A2).

Commissioning Levelflex M FMP41C with HART/4...20 mA

40 Endress + Hauser

The basic setup is sufficient for successful commissioning in most applications. The Levelflex is initially adjusted at the factory to the probe length ordered, so that in most cases only the application parameters, that automatically adapt the device to the measuring conditions, need to be entered. For models with current output, the factory adjustment for zero point and span is F 4 mA and 20 mA, for digital outputs and the display module 0 % and 100 %.A linearisation function with max. 32 points, that is based on a manually or semi-automatically input table, can be activated on-site or via remote operation. This function enables, for example, the conversion of the level into units of volume or weight.

Note! The Levelflex M allows to check for broken probe. On delivery, this function is switched off, because otherwise shortening of the probe would be mistaken for a broken probe. In order to activate this function, perform the following steps:

1. With the probe uncovered, perform a mapping ("range of mapping" (052) and "start

mapping." (053)).

2. Activate the "broken probe det" (019) function in the "safety settings" (01) function

group.

Complex measuring operations necessitate additional functions that the user can use to customise the Levelflex as necessary to suit his specific requirements. The functions available to do this are described in detail in the BA245F – "Description of the instrument functions" on the enclosed CDROM. Comply with the following instructions when configuring the functions in the "basic setup" (00):

• Select the functions as described on → ä 28.

• Certain functions (e.g. starting an interference echo mapping (053)) prompt you to confirm your data entries. Press

or S to select "YES" and press F to confirm. The function is now started.

• If you do not press a key during a configurable time period (→ function group "display (09)") , an automatic return is made to the home position (measured value display).

Note!

• The instrument continues to measure while data entry is in progress, i.e. the current measured values are output via the signal outputs in the normal way.

• If the envelope curve mode is active on the display, the measured values are updated in a slower cycle time. Thus, it is advisable to leave the envelope curve mode after the measuring point has been optimised.

• If the power supply fails, all preset and parameterised values remain safely stored in the EEPROM.

Caution! All functions are described in detail, as is the overview of the operating menu itself, in the manual BA245F – "Description of the instrument functions" on the enclosed CD-ROM.

Function "measured value" (000)

This function displays the current measured value in the selected unit (see "customer unit" (042)) function). The number of digits after decimal point can be selected in the "no.of decimals" (095) function.

Function "tank properties" (002)

This function is used to select the tank properties.

Selection:

• standard

• aluminium tank

• plastic tank

• bypass / pipe

• coax probe

• concrete wall

standard

The "standard" option is recommended for normal containers for rod and rope probes.

aluminium tank

The "aluminium tank" option is designed especially for high aluminium silos that cause an increased level of noise when empty. This option is only useful for probes longer than (< 4 m). For short probes (< 4 m) select the "standard" option!

Note! If "aluminium tank" is selected, the device calibrates of its own accord when first filled, depending on the medium's properties. Slope errors can, therefore, occur when beginning the first filling procedure.

plastic tank

Select the "plastic tank" option when installing probes in wood or plastic containers without metallic surfaces at the process connection (see installation in plastic containers). When using a metallic surface at the process connection, the "standard" option is sufficient!

Note! In principle the employment of a metallic surface area should be preferred at the process connection!

bypass / pipe

The "bypass / pipe" option is designed especially for the installation of probes in a bypass or a stilling well. If this option is selected, the upper blocking distance is preset to 100 mm.

coax probe

Select the "coax probe" option when using a coaxial probe. When this setting is made, the evaluation is adapted to the high sensitivity of the coax probe. This option should, therefore, not be selected when using rope or rod probes.

concrete wall

The "concrete wall" option takes into account the signal-damping property of concrete walls when mounting with < 1 m distance to the wall.

Function "medium property" (003)

This function is used to select the dielectric constant.

Use this function at part-covered probe. Choosing function "manual" or "probe free" at free probe.

• mapping is carried out up to the currently measured echo

• The range to be suppressed is suggested in the "range of mapping" (052) function

Anyway, it is wise to carry out a mapping even in this case.

Note! At free probe, the mapping should be confirmed with the choice "probe free".

dist. too small

• At the moment, an interference is being evaluated

• Therefore, a mapping is carried out including the presently measured echoes

• The range to be suppressed is suggested in the "range of mapping" (052) function

dist. too big

• This error cannot be remedied by interference echo mapping

• Check the application parameters (002), (003), (004) and "probe length." (031)

dist. unknown

If the actual distance is not known, no mapping can be carried out.

manual

A mapping is also possible by manual entry of the range to be suppressed. This entry is made in the "range of mapping" (052) function.

Caution! The range of mapping must end 0.3 m (20") before the echo of the actual level. In case of empty vessel it is possible to make a map over the whole probe length.

probe free

If the probe is uncovered, mapping is carried out along the whole probe length.

Caution! Only begin mapping in this function if the probe is safely uncovered. Otherwise, the device will not make correct measurements!

6.8.2 Envelope curve with the ToF Tool

After the basic setup, an evaluation of the measurement using the envelope curve is recommended (→ ä 58).

L00-FMP4xxxx-20-00- 00-en-007

Note! For the optimization of the measurement the installation of the Levelflex in another place can be executed when enterference echoes.

An evaluation of the measurement with the aid of the envelope curve

Typical curve shape:

The following examples display typical curve shapes for a rope or rod probe in an empty tank. For all probe types, a negative probe end signal is shown. For rope probes, the end weight causes an additional preliminary positive echo (see rope probe diagram).

L00-FMP40xxx-05-00-0 0-en-024

Level echoes are detected as positive signals in the envelope curve. Interference echoes can be both positive (e.g. reflections from internals) and negative (e.g. nozzles). The envelope curve, the map and the differential curve are used for the evaluation.Level echoes are searched for in the differential curve.

Evaluation of the measurement:

• The map must correspond to the course of the envelope curve (for rod probes up to approx. 5 cm and for rope probes up to approx. 25 cm before the end of the probe) when the tank is empty.

• Amplitudes in the differential curve should be at a level of 0 mV when the tank is empty and lie within the span that is specified by the probe-specific blocking distances. In order to not detect any interference echoes, there must be no signals that exceed the echo threshold when the tank is empty.

• For partially-filled tanks, the map may only differ from the envelope curve at the position of the level echo. The level signal is then detected unequivocally as a positive signal in the differential curve. For detecting the level echo, the amplitude must lie above the echo threshold.

7 Maintenance

The Levelflex M measuring instrument requires no special maintenance.

Exterior cleaning

When cleaning the Levelflex M , always use cleaning agents that do not attack the surface of the housing and the seals.

Repairs

The Endress+Hauser repair concept assumes that the measuring devices have a modular design and that customers are able to undertake repairs themselves. Spare parts are contained in suitable kits. They contain the related replacement instructions. All the spare parts kits which you can order from Endress+Hauser for repairs to the Levelflex M are listed with their order numbers on → ä 70 and

73. Please contact Endress+Hauser Service for further information on service and spare parts.

Repairs to Ex-approved devices

When carrying out repairs to Ex-approved devices, please note the following:

• Repairs to Ex-approved devices may only be carried out by trained personnel or by Endress+Hauser Service.

• Comply with the prevailing standards, national Ex-area regulations, safety instructions (XA) and certificates.

• Only use original spare parts from Endress+Hauser.

• When ordering a spare part, please note the device designation on the nameplate. Only replace parts with identical parts.

• Carry out repairs according to the instructions. On completion of repairs, carry our the specified routine test on the device.

• Only Endress+Hauser Service may convert a certified device into a different certified variant.

• Document all repair work and conversions.

Replacement

After a complete Levelflex M or electronic module has been replaced, the parameters can be downloaded into the instrument again via the communication interface. Prerequisite to this is that the data were uploaded to the PC beforehand using the ToF Tool. Measurement can continue without having to carry out a new setup.

• You may have to activate linearisation (see BA245F – "Description of the instrument functions" on the enclosed CD-ROM.)

• You may need to record the tank map again (see Basic Setup)

After an probe or electronic has been replaced, a new calibration must be carried out. This is described in the repair instructions.

9.5 Return

The following procedures must be carried out before a transmitter is sent to Endress+Hauser e.g. for repair or calibration:

• Remove all residue which may be present. Pay special attention to the gasket grooves and crevices where fluid may be present. This is especially important if the fluid is dangerous to health, e.g. corrosive, poisonous, carcinogenic, radioactive, etc.

• Always enclose a duly completed "Declaration of contamination" form (a copy of the “Declaration of contamination” is included at the end of this operating manual). Only then can Endress +Hauser transport, examine and repair a returned device.

• Enclose special handling instructions if necessary, for example a safety data sheet as per EN 91/ 155/EEC.

Additionally specify:

• An exact description of the application

• The chemical and physical characteristics of the product

• A short description of the error that occurred (specify error code if possible)

• If necessary, give the error code

9.6 Disposal

In case of disposal please seperate the different components according to their material consistence.

10.1.1 Input

Measured variable The measured variable is the distance between a reference point (see Fig. on → ä 14) and the

product surface. Subject to the input empty distance (E, see Fig. on → ä 86), the level is calculated. Alternatively, the level can be converted by means of linearisation (32 points) into other variables (volume, mass).

10.1.2 Output

Output signal 4…20 mA with HART protocol

Signal on alarm Error information can be accessed via the following interfaces:

•Local display:

– Error symbol (→ ä 31) – Plain text display

• Current output, signal on error can be selected (e.g. according to NAMUR recommendation NE

43).

• Digital interface

Linearization The Levelflex M linearisation function enables conversion of the measured value into any desired

length or volume units and mass or %. Linearisation tables for volume calculation in cylindrical tanks are pre-programmed. Any other tables from up to 32 value pairs can be input manually or semiautomatically. The creation of a linearisation table with the ToF Tool or FieldCare is particularly convenient.

Endress + Hauser 79

Cleaning the probe Depending on the application, soilings or sediments can accumulate on the probe. A thin, even layer

only influences measurement slightly. Thick layers can dampen the signal and then reduce the measuring range. Heavy, uneven build-up, adhesion e.g. through crystallisation, can lead to incorrect measurement. In this case, we recommend that you use a non-contact measuring principle, or check the probe regularly for soiling

Electromagnetic compatibility (EMC)

When installing the probes in metal and concrete tanks and when using a coax probe:

• Interference Emission to EN 61326, Electrical Equipment Class B

• Interference immunity to EN 61326, Annex A (Industrial area) and NAMUR Recommendation NE 21 (EMC)

The measured value can be affected by strong electromagnetic fields when installing rod and rope probes without a shielding/metallic wall, e.g. plastic, and in wooden silos.

• Interference emission to EN 61326, Class A equipment.

• Interference immunity: the measured value can be affected by strong electromagnetic fields.

10.1.5 Operating conditions: Process

Process temperature range The maximum permitted temperature at the process connection (see Figure for measuring point) is

determined by the process connection ordered:

For FMP41C with Endress+Hauser adapter 43 mm: 0 °C ... 150 °C (32 °F...302 °F).

Lateral load-bearing capacity of the rod probe: 30 Nm

Process pressure limits All models: Vacuum up to max. 40 bar (585,9psi).

For FMP41C with Endress+Hauser universal adapter: max. 6 bar (87 psi). For FMP41C with Tri-Clamp see ordering Information.

11.2 Description of functions

Note! A detailed description of the function groups, functions and parameters is given in the documentation BA245F – "Description of the instrument functions" on the enclosed CD-ROM.

11.3 Function and system design

11.3.1 Measuring principle

The Levelflex is a "downward-looking" measuring system that functions according to the ToF method (ToF = Time of Flight). The distance from the reference point (process connection of the measuring device → ä 13) to the product surface is measured. High-frequency pulses are injected to a probe and led along the probe. The pulses are reflected by the product surface, received by the electronic evaluation unit and converted into level information. This method is also known as TDR (Time Domain Reflectometry).

L00-FMP41Cxx-15-00-0 0-en-001

Input

The reflected pulses are transmitted from the probe to the electronics. There, a microprocessor analyses the signals and identifies the level echo, which was generated by the reflection of the highfrequency pulses at the product surface. This clear signal finding benefits from the more than 30 years of experience with pulse time-of-flight procedures that have been integrated into the development of the PulseMaster

Software.

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 Reference point for "E" see above diagram, Details → ä 39.

The Levelflex possesses functions for the interference echo suppression that can be activated by the user. They guarantee that interference echoes from e.g. internals and struts are not interpreted as level echoes.

11.3.2 Equipment architecture

Stand-alone

• Power supply directly from power line (4-wire) or from transmitter power supply unit (2-wire).

• Operation by on-site display or remote operation via HART protocol.

L00-FMxxxxxx-14-00-06-en-008

If the HART communication resistor is not installed in the supply device and HART protocol communication is to be carried out, it is necessary to insert a ≥ 250 Ω communication resistor into the 2-wire line.

On-site operation:

• with display and operating module VU331,

• with a Personal Computer, FXA193 (RS232C) or FXA291 and ToF Adapter FXA291 (USB) and the operating software "ToF Tool - FieldTool Package" respectively "FieldCare". The ToF Tool is a graphical operating software for instruments from Endress+Hauser that operate based on the time-of-flight principle (radar, ultrasonic, guided micro-impulse). It assists with commissioning, securing data, signal analysis and documentation of the measuring point.
