Safety instructions	Micropilot M FMR244 HART 4 to 20 mA

1 Safety instructions

1.1Designated use

The Micropilot M is a compact radar level transmitter for the continuous, contactless measurement of liquids, pastes, sludge and 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 1 mW (average power output 1 μW). Operation is completely harmless to humans and animals.

1.2Installation, 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.

1.3Operational safety and process safety

Alternative monitoring measures must be taken to ensure operational safety and process safety during configuration, testing and maintenance work on the device.

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 Additional documentation is mandatory.

•Ensure that all personnel are suitably qualified.

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

1.3.1FCC 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.

2.This device must accept any interference received, including interference that may cause undesired operation.

"Caution!Changes or modifications not expressly approved by the part responsible for compliance could void the user’s authority to operate the equipment.

3.3.2Engineering hints

Orientation
• Recommended distance (1) wall – outer
edge of nozzle: ~1/6 of tank diameter.	2	3	4
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.	1
• 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").

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.

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 NH3 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.

Micropilot M FMR244 HART 4 to 20 mA	Mounting

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

A1.4 to 1.9 non-conducting liquids, e. g. liquefied gas1)

B1.9 to 4 non-conducting liquids, e. g. benzene, oil, toluene, …

C4 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 εr.

	Media group	DC (εr)		Examples	Signal attenuation
			–	Plastic granulate
	A	1.6 to 1.9	–	White lime, special cement	19 to 16 dB
			–	Sugar
	B	1.9 to 2.5	–	Portland cement, plaster	16 to 13 dB
			–	Grain, seeds
	C	2.5 to 4	–	Ground stones	13 to 10 dB
			–	Sand
	D	4 to 7	–	Naturally moist (ground) stones, ores	10 to 7 dB
			–	Salt
			–	Metallic powder
	E	> 7	–	Carbon black	< 7 dB

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.
