3.3.2 Engineering hints

Orientation

• Recommended distance (1) wall – outer edge of nozzle: ~1/6 of tank diameter.

Nevertheless the device should not be installed closer than 15 cm (5.91 in) to the tankwall.

• 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 (→ ä 65, "Accessories").

234

Tank installations

• Avoid any installations (1), like limit switches, temperature sensors, etc., inside the signal beam (→ ä 16, "Beam angle").

• Symmetrical installations (2), i. e. vacuum rings, heating coils, baffles, 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: "Installation in tank (free space)", → ä 21

• Stilling well: a stilling well can always be used to avoid interference.

• 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, there should be no such interfering installations in the signal beam. Please contact Endress+Hauser for further information.

Measuring conditions in liquids

Note!

• In case of boiling surfaces, bubbling or tendency for foaming, use FMR230 or FMR231. Depending on its consistence, foam can either absorb microwaves or reflect them off the foam surface. Measurement is possible under certain conditions.

• In case of heavy steam development or condensate the max. measuring range of FMR240 may decrease depending on density, temperature and composition of the steam → use FMR230 or FMR231.

• For the measurement of absorbing gases such as ammonia NH

or some fluorocarbons 1),

please use FMR230 in a stilling well.

• The measuring range begins, where the beam hits the tank bottom. Particularly with dish bottoms or conical outlets the level cannot be detected below this point.

• In case of media with a low dielectric constant (groups A and B), the tank bottom can be visible through the medium at low levels (low height C). Reduced accuracy has to be expected in this range. If this is not acceptable, we recommend positioning the zero point at a distance C (see Fig.) above the tank bottom in these applications.

• In principle it is possible to measure up to the tip of the antenna with FMR230/231/240. However, due to considerations regarding corrosion and build-up, the end of the measuring range should not be chosen any closer than A (see Fig.) to the tip of the antenna. For FMR244/245, the end of measuring range should not be chosen closer than A (see Fig.) to the tip of the antenna, especially if there is development of condensate.

• The smallest possible measuring range B depends on the antenna version (see Fig.).

• The tank diameter should be greater than D (see Fig.), the tank height at least H (see Fig.).

Measuring conditions in solids

• The measuring range begins, where the beam hits the bottom. Particularly with 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 Technical Information TI00345F/00/EN).

• In case of media with a low dielectric constant (groups A and B), the 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 above the bottom (see Fig.).

• In principle it is possible to measure up to the tip of the antenna with the Micropilot M. However, due to considerations regarding abrasion and build-up and depending on the orientation of the product surface (angel of repose), the end of the measuring range should be at a distance of A, see Fig. If required, and if some conditions (high DC value, flat angle of repose) are met, shorter distances can be achieved.

Measuring range in liquids

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:

• 40 m (131 ft) for basic version

• 70 m (230 ft) with additional option F (G), → ä 7, "ordering information" 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 group DC (εr) Examples

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, i. e. use FMR230 in a stilling well.

Measuring range in solids

The FMR244 with 80 mm (3") antenna or FMR240 with 100 mm (4") horn antenna and additional option F (= advanced dynamics) is also suited for solid applications. The usable measuring range depends on the reflection properties of the medium, the mounting position and interference reflections which may be present. The maximum configurable measuring range for the Micropilot M FMR240 with 100 mm (4") horn antenna and additional option F (= advanced dynamics) is 30 m (98 ft) in solid applications. It is recommended to use the variable flange seal for alignment (see Technical Information TI00345F/00/EN).

Reduction of the max. possible measuring range through:

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

• 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.

The following table describes the media groups and the dielectric constant

Media group DC (

A 1.6 to 1.9

B 1.9 to 2.5 – Portland cement, plaster 16 to 13 dB

C 2.5 to 4

For installations in a stilling well, follow the engineering hints (→ ä 14) and note the following points:

• Marker is aligned toward slots.

• Install the device using the threaded boss (AF60) only. Observe the max. torque of 20 Nm (14.75 lbf ft).

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

• Measurements can be performed through an open full bore ball valve without any problems.

Recommendations for the stilling well

At the construction of a stilling well, please note the following points:

• Metal (no enamel coating, plastic coating on request).

• Constant diameter.

• Stilling well diameter not larger than antenna diameter.

• Weld seam as smooth as possible and on the same axis as the slots.

• Slots offset 180° (not 90°).

• Slot width respectively diameter of holes max. 1/10 of pipe diameter, de-burred. Length and number do not have any influence on the measurement.

• At any transition (i. e. when using a ball valve or mending pipe segments), no gap may be created exceeding 1 mm (0.04 in).

• The stilling well must be smooth on the inside (average roughness Rz ≤ 6.3 μm (≤ 248 μin)). Use extruded or parallel welded stainless steel pipe. An extension of the pipe is possible with welded flanges or pipe sleeves. Flange and pipe have to be properly aligned at the inside.

• Do not weld through the pipe wall. The inside of the stilling well must remain smooth. In case of unintentional welding through the pipe, the weld seam and any unevenness on the inside need to be carefully removed and smoothened. Otherwise, strong interference echoes will be generated and material build-up will be promoted.
