Function and system design

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) 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.

InputThe 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 high-frequency pulses at the product surface. This clear signal finding benefits from the many years 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.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.

OutputThe 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 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, measurement in technical units and provides a linear output signal for spherical and horizontal cylindrical containers as well as those with conical outlets.

Equipment architecture Probe selectionThe various types of probe in combination with the process connections are suitable for the following applications:

1) For versions with separate electronics with 3m cable the maximum measuring range is reduced to 30m/98.43ft. If the distance sleeve is used, the maximum measuring range is reduced to 34m/111.55ft.

2) This is the maximum load on the roof. In case of an overload, the process sealing remains tight.

Input

Measured variable The measured variable is the distance between a reference point (see Fig. on page 3) and a reflective surface (e.g. medium surface).Subject to the input zero point (E, see Fig. on page 3) the level is calculated.Alternatively, the level can be converted by means of linearisation into other variables (volume, mass).

Measuring range The following table describes the media groups and the possible measuring range as a function of the media group.

The respective lower group applies for very loose or loosened bulk solids.Reduction of the max. possible measuring range through:• Extremely loose surfaces of bulk solids, e.g. bulk solids with low bulk weight for pneumatic

filling.• Build-up, above all of moist products.

Blocking distance The upper blocking distance (= UB) is the minimum distance from the reference point of the measurement (mounting flange) to the maximum level.The lower blocking distance (= LB) is the range of the probe from the lower edge calculated upwards, in which exact measurement is not possible.

Operating conditions / Installation

Installation instructionsfor level measurementin bulk solids silos

Mounting location• Recommended distance B (see page 8)

wall-mounted rope probe: ~1/6...1/4 of the container diameter (min. 100 mm, concrete silos: min. 500 mm).

• Not central (2) in metallic silos.• Not in the filling curtain (3).• There are no minimum requirements for the

distance between the end of the probe and floor of the silo. However, when mounted in a cone, it should be either fixed (see page 15) or should be so short, that a contact to the cone is not possible.

• Position the probe such that it is exposed to the minimum side forces.

• Rope and silo roof must be able to withstand the tensile forces of the product.

• Temperature conditions must be met (see page 23).

• It is recommended that a protective cover (1) is used, in order to protect the transmitter against direct sunlight or rain (see »Accessories« on page 34.).

Other installations• Ensure that internals (1) such as limit

switches, temperature sensors etc. are not closer than 300 mm to the probe.

• Probe must within the measuring span not touch any internals during operation.The probe end (2) may be fixed to ensure that.

Optimization options• If the product becomes extremely

electrostatically charged during processing, an earthing chain (3) should be mounted in the filling curtain.

• If the probe moves closer than 100 mm for metal silos or 500 mm for concrete silos to internals/ wall during operation, the end of the rope should be secured (2).

• Select length of the probe corresponding to the desired measuring range. It can be simply shortened on site.

Installation can be carried out with a welding boss and the device’s threaded connection. Installation does not have to be flush. Both a protrusion of the socket in the inside of the container and a socket that is up to approx. 100 mm long are acceptable.However, installation in the nozzle is also possible. DN100 / 4" nozzles with height of up to 150 mm / 6" are ideal. Larger nozzle heights are acceptable, when fixing the probe end or using a centering disk in the nozzle (see page 15) prevents the probe touching the lower edge of the nozzle.Note!Please contact Endress+Hauser regarding applications with larger nozzle diameters>DN250/10".

Adapter flange FAU 20When installing the Levelflex in nozzles of > 100 mm / 4", signals are generated by reflections on the nozzle wall, which can sometimes lead to faulty measurements in the case of products with small dielectric constants With nozzle diameters of 150 mm / 6", 200 mm / 8" or 250 mm / 10", therefore, a special flange with a “horn adaptor” must be fitted. Nozzles with nominal diameters greater than DN 250 / 10" should be avoided. Note!Please contact E+H if you wish to install the Levelflex in nozzles of > DN 250.

Securing to the weightIf a Levelflex rope probe needs to be mounted closer than 300 mm to installations/struts, or if the probe is to be mounted not vertically, the end of the probe must be fixed. The weights have internal threads for this purpose:• For a 4mm rope: M14• For a 6mm rope: M20

The Levelflex must be mounted with lateral sag of the rope:The rope must be able to make a deflection of >= 1cm / m or 1"/100" of the rope length in the cen-tre, otherwise there may occur excessive pulling forces on the rope (see fig. on page 16).

The Levelflex must be mounted in such a way that the rope probe is loose The rope must make a deflection of >= 1cm / m or 1"/100" of the rope length possible in the centre, without power output. The probe weight can be mounted using appropriate bolts (M14 for a 4mm rope, M20 for a 6mm rope). This is simplest and a safe electrical connection should be made with a metal holder in this case. 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 page 35).

Centering disc FAU 30When installing rope probes in nozzles with heights of > 150 mm / 6", there is a risk, depending on the movement of the material in the silo, that the rope probe may touch the lower edge of the nozzle. This could impair correct measurement and damage the rope. In order to install the Levelflex in nozzles of up to 600 mm in height, we recommend using a centering disk. Order codes for specific nozzle nominal diameters and heights can be found on page 35.Together with the centering disc a steel rod is delivered to be screwed between rope and process connection. Please order a probe with a length by the length of the rod, otherwise the rope has to be shorted on site.

Installation inbulk solids silos

Orientation• Use rope probes:

– for bulk solids with bulk weight not exceed-ing 0.6 t/m³ and length up to 20 m, prefer-ably 4 mm rope probe

– for bulk solids with bulk weight of >0.6 t/m³ or length > 20 m, preferably 6 mm rope probe

• As far away as possible from filling and emptying openings, in order to keep wear low

• Very small wall distances are also acceptable in metal and plastic silos, if you have ensured that the probe is not touching the wall. Not exactly central for metal silos and ideal for concrete silos 1 m, min. 0.5 m.

• The end of the probe needs to be secured if the probe would otherwise touch the silo wall, the cone or another part. This is what the internal thread in the probe weight is intended for.

• Follow installation instructions on page 13.• After mounting, the housing can be turned

350°, in order make access to the display and the connection compartment easier.

Important!• 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).

• In order to prevent an extremely high tensile load and the risk of the rope breaking, 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 of the rope length.

Installation in plastic silosNote!Please note that for rod and rope probes only with a metallic surface at the process connection an optimal performance can be guaranteed.When installing the probe in plastic silos, whose silo cover is also made of plastic, the probes must either be mounted in a ≥ DN50 / 2" metallic flange, or a metal sheet with diameter of ≥ 200 mm must be mounted under the screw-in piece.

Installation in concrete ceilingInstallation, for example, into a thick concrete ceiling should be made flush with the lower edge. Alternatively, the probe can also be installed into a pipe that must not protrude over the lower edge of the silo ceiling. Installation suggestions see diagram.

Shortening rope probeThe rope can be easily shortened on site. After shortening the probe rope, the new length must be input in the Levelflex.

Rope loadThe tensile forces on a fixed rope are much larger than on a rope with weight. In the following diagrams, the tensile forces on the probe rope are shown for different bulk solids, silo diameters, and rope diameter as a function of level.The forces increase with the height of the product the silo diameter, and the density of the solid.Always use an additional safety factor that is sufficient for your application.

Rope loadDie Silodecke bzw. das Sondenseil muß die Zugkraft des Produkts aushalten.Die Zugkraft ist von der Schüttdichte und dem Reibungskoeffizienten des Materials, der Höhe und des Durchmessers des Silos, sowie der ausgewählten Sonde abhängig.

Forces for suspended (not secured) probe:

The specified tensile forces are typical values for the bulk solid's mass flow.No values can be specified for funnel flow.

Installation instructionsfor level measurementin liquid tanks

Orientation• Recommended distance B wall-mounted

rope probe: ~1/6...1/4 of the container diameter (min. 100 mm, concrete silos: min. 500 mm).

• Not central (2) in metallic silos.• Not in the filling curtain (3).• There are no minimum requirements for the

distance between the end of the probe and floor of the tank.

• Temperature conditions must be met.• It is recommended that a protective cover (1)

be used, in order to protect the transmitter against direct sunlight or rain. Mounting and demounting are carried out simply with a clamp (see »Accessories« on page 34.).

Tank installations• Ensure that internals (1) such as limit

switches, temperature sensors etc. are not closer than 300 mm to the probe.

• Probe must not touch any internals during operation - secure end of the probe(2), whilst not causing it to slacken through over-tightening

Optimization options• If the probe moves closer than 100 mm to

internals/ wall during operation, the end of the rope should be secured (2).

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

• Bypass and stilling well (only for fluids): A bypass or stilling well or a coax probe can always be used to prevent the influence of interferences

Installation influid tanks

Standard installationUsing a coax probe offers great advantages when the viscosity of the product is low and it is certain that the product does not accumulate build-up:• Greater reliability:

As of dielectric constant=1.4, measurement functions independently of all electrical properties in all fluids.

• Internals in the tank do not have any influence on measurement.• Higher lateral load-bearing capacity than rod probes.• If it is not possible to mount the Levelflex directly onto the container, a mounting nozzle must be

used. The dimensions of the nozzle do not have any influence on the device with a coax probe.• For higher viscosity a rod probe is recommended.

Installation in horizontal cylindrical and standing tanks• Use a coax or rod probe for measuring

ranges up to 4 m. For anything over this or if there is too free cover space use a 4 mm rope probe.

• Installation and possible fixing as with bulk solids.

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

• Do not mount a rod or rope probe (1) exactly central when using metallic containers. Central mounting doesn‘t impair coax probe (2) performance.

• When installing in tanks with a lot of internals or internals situated close to the probe: Use a coax probe.

Installation in underground tanks• Use coax probe for long nozzles with large

diameters.

Installation for difficult to access process connections

For tight spaces or temperatures above that in the graphic (see page 12), the electronics housing can be ordered with distance pipe or connecting cable (seperate housing).

Installation in stilling well or bypass• A rod probe can be used for pipe diameters

up to 100 mm, for diameters above that the adapter flange FAU 20 is recommended for low dielectric constant material.

• Installation is possible in both metallic and plastic pipes. It is also possible to close the pipe to prevent corrosion of the probe by the liquid. In this case the pipe diameter should not exceed 50 mm.

• When installing a rod probe into a metallic pipe with internal diameter of up to 100 mm, you have all the advantages of a coax probe.

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

Installation with distance pipe• Follow installation instructions on page 13.• After mounting, the housing can be turned

350°, in order make access to the display and the connection compartment easier.

• The max. measuring range is reduced to34 m.

Ambient temperature for the transmitter: -40 °C … +80 °C (-40 °F … +176 °F)The functionality of the LCD display may be limited for temperatures Ta<-20 °C and Ta>+60 °C.A weather protection cover should be used for outdoor operation if the instrument is exposed to direct sunlight.

Ambient temperature limits

For process connection temperatures above 80 °C, the allowed ambient temperature at the housing is reduced according to the following diagram:

Storage temperature -40 °C … +80 °C (-40 °F … +176°F)

Cleaning of 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, above all adhesion e.g. through crystallisation, can lead to incorrect measurement. In this case, it is recommended that you use a non-contact measuring principle, or check the probe regularly for soiling.
