Safety instructions Micropilot M FMR250 with HART/4...20 mA

1 Safety instructions

1.1 Designated use

The Micropilot M FMR250 is a compact level radar for the continuous, contactless measurement of predominantly solids. The device can also be freely mounted outside closed metal vessels because of its operating frequency of about 26 GHz and a maximum radiated pulsed energy of 1mW (average power output 1 µW). Operation is completely harmless to humans and animals.

1.2 Installation, commissioning and operation

The Micropilot M has been designed to operate safely in accordance with current technical, safety and EU standards. If installed incorrectly or used for applications for which it is not intended, however, it is possible that application-related dangers may arise, e.g. product overflow due to incorrect installation or calibration. For this reason, the instrument must be installed, connected, operated and maintained according to the instructions in this manual: personnel must be authorised and suitably qualified. The manual must have been read and understood, and the instructions followed. Modifications and repairs to the device are permissible only when they are expressly approved in the manual.

1.3 Operational safety

1.3.1 Hazardous areas

Measuring systems for use in hazardous environments are accompanied by separate "Ex documentation", which is an integral part of this Operating Manual. Strict compliance with the installation instructions and ratings as stated in this supplementary documentation is mandatory.

• Ensure that all personnel are suitably qualified.

• Observe the specifications in the certificate as well as national and local standards and regulations.

1.3.2 FCC approval

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

3.3.2 Engineering hints

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.

• 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 (→ Chap. 8 on Page 64).

• In extremely dusty applications, the integrated air purge connection can prevent clogging of the antenna.

234

L00-FMR250xx-17-00 -00-xx-003

Vessel installations

• Avoid any installations (1), like limit switches, struts, etc., inside the signal beam (refer to beam angle see "Beam angle" on Page 16).

• 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°.

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 measuring distance D:

Micropilot M FMR250 with HART/4...20 mA Installation

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.

• 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 =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=400 mm (see Fig.) to the tip of the antenna.

• The smallest possible measuring range B=500 mm (see Fig.).

Installation Micropilot M FMR250 with HART/4...20 mA

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.

To achieve an optimised Signal strength it is recommended to use an antenna with as large as possible diameter (DN200/8" parabolic antenna, DN100/4" horn).

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

Media group DC (εr) Examples Signal attenuation

A 1.6...1.9

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

C 2.5...4
