3.1 Quick installation guide

3.1.1 Installation only in stilling well

A0021216

The performance of the planar antenna is not dependent on the alignment or geometry of standard stilling wells. No special alignment is required. However, make sure that the planar antenna is installed vertically relative to the stilling well axis.

3.2 Incoming acceptance, transport, storage

3.2.1 Incoming acceptance

Check the packing and contents for any signs of damage. Check the shipment, make sure nothing is missing and that the scope of supply matches your order.

3.2.2 Transport

Follow the safety instructions and transport conditions for devices of more than 18 kg (39.69 lbs).

3.2.3 Storage

Pack the measuring device so that is protected against impacts for storage and transport. The original packing material provides the optimum protection for this. The permissible storage temperature is -40 to +80 °C (-40 to +176 °F).

3.3 Installation Conditions

3.3.1 Engineering hints

Measuring conditions

• 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.

•For overfill prevention, it is possible to define a safety distance (SD) additionally to the blocking distance (BD).

• Depending on its consistence, foam can either absorb microwaves or reflect them off the foam surface. Measurement is possible under certain conditions.

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

• The zero should be positioned at the end of the tube, as the electromagnetic waves do not propagate completely outside the tube. It must be taken into account that the accuracy may be reduced in the area C. In order to guarantee the required accuracy in these cases, it is recommended to position the zero-point at a distanc C above the tank bottom (see Fig.).

• In applications with planar antennas, especially for media with low dielectric constants (media group A and B,  ä 12), the end of the measuring range should not be closer than 1 m (3.3 ft) to the flange (cf. A in following figure).

• The safety distance (SD) is set to 0.5 m (1.6 ft) by default, generating an alarm in case the product level rises inside the safety distance.

Mounting Micropilot S FMR532 4 to 20 mA HART

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 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 (r) Examples

A 1.4 to 1.9

B 1.9 to 4

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

Non-conducting liquids, e.g. liquefied gas (LPG). For more information please contact your Endress+Hauser representative.

Micropilot S FMR532 4 to 20 mA HART Mounting

NOTICE

Recommendations for the stilling well

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

• Constant diameter.

• When using a FMR532, an increase of the pipe diameter from DN 150 to DN 200 / DN 200 to DN 250 / DN 250 to DN 300 is acceptable. A larger step-width for the increase of the pipe diameter (e.g. DN 150 to DN 300) is possible if the upper part of the pipe has a suitable length. The length of the stilling well enlargement must be kept. In this case, the upper end of the pipe must have a minimum length of 0.5 m (1.6 ft) before the diameter increases (refer to table,  ä 16). If the length is less than "L", please contact Endress+Hauser in order to determine a suitable antenna adapter (separable antenna horn). Ideally, a sample hatch is used.

• Any rectangular increase of the pipe diameter has to be avoided.

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

• For best radar propagation behavior holes it is recommended to have holes instead of slots. If slots can not be avoided, they should be as thin and short as possible.

• The diameter of the holes (deburred) can be up to 1/7 of the pipe diameter but should not exceed 30 mm (1.18 in).

• Length and number of the holes do not affect the measurement.

• Maximum gap allowed between the antenna/horn and the inside of the stilling well is 5 mm (0.2 in).

• At any transition (e.g. 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. Use extruded or parallel welded 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 smoothed. Otherwise, strong interference echoes will be generated and material build-up will be promoted.

Selection of antenna size

‣ Select antenna extension as big as possible. For intermediate sizes

(e.g. 180 mm (7.09 in)) select next larger antenna extension and adapt it mechanically. Maximum gap allowed between the antenna/horn and the inside of the stilling well is 5 mm (0.2 in).

‣ The antenna extension of the FMR532 is mounted with defined pressure.

It is strongly recommended not to dismantle this antenna.

‣ Dimensions of a nozzle for manual gauging must be adapted to the dimensions of the

horn antenna used, compare  ä 16.

3.4.4 Installation with Endress+Hauser UNI flange

Installation hints

Endress+Hauser UNI flanges are designed for non-pressurized operation respectively max. 1 bar (14.5 psi) absolute pressure. The number of bolts has sometimes been reduced. The bolt-holes have been enlarged for adaption of dimensions, therefore, the flange needs to be properly aligned to the counterflange before the bolts are tightened.

4.1 Quick wiring guide

When grounding conductive screens, the corresponding directives EN 60079-14 and EN 1127-1 must be observed. Recommendation for safe grounding of conductive screens:

Before connection please note the following:

‣ The power supply must be identical to the data on the nameplate. ‣ Switch off power supply before connecting the device. ‣ Connect equipotential bonding to transmitter ground terminal before connecting the

device.

‣ Tighten the locking screw:

It forms the connection between the antenna and the housing ground potential.

‣ When you use the measuring system in hazardous areas, make sure you comply with

national standards and the specifications in the safety instructions (XA’s)

4.1.1 Wiring

Before connection please note the following:

‣ The power supply to be delivered by a transmitter supply unit. ‣ Befor removing housing cover at seperate connection compartment turn off the power

supply!

Insert cable through gland . Use screened, twisted 2-wire or 4-wire cable.

Only ground screening of the line on sensor side.

Make connection (see pin assignment). Tighten cable gland. Replace and tighten off housing cover. Switch on power supply.

A Micropilot S situated in a hazardous area is connected as a single device to a power supply unit and transmitter situated outside of the hazardous area. In this case, it is recommended that the screen be connected directly to the Micropilot at the housing’s earth, whereby the Micropilot S and the power supply unit are connected to the same potential equalization line.

4.1.2 Wiring with Tank Side Monitor NRF590

Before connection please note the following:

‣ Make sure you use the specified cable gland. ‣ Befor removing housing cover at seperate connection compartment turn off the power

supply!

Insert cable through gland . Use screened, twisted 2-wire or 4-wire cable.

Only ground screening of the line on sensor side.

Make connection (see pin assignment). Tighten cable gland. Replace and tighten off housing cover. Switch on power supply.

The Micropilot S is - possibly in combination with other devices connected to a Tank Side Monitor in a hazardous area. In this case, it is recommended that you ground the cable screen centrally at the NRF590 and connect all devices to the same potential equalization line (PML). If, for functional reasons, a capacitive coupling is required between local earth and screen (multiple grounding), ceramic condensers with a dielectric strength of min. 1500 Veff must be used, whereby the total capacitance of 10 nF must not be exceeded. Notes on grounding interconnected intrinsically safe devices are provided by the FISCO model. If there is no way to set a ground cable between NRF590 and Micropilot S it is possible to ground single side (grounding on side NRF590). In this case it’s imperative to ground the shield (on Micropilot S side) via a ceramic capacitor with a maximum capacitance of 10 nF and a minimum insulating voltage of 1500 V.

Micropilot S FMR532 4 to 20 mA HART Wiring

Overvoltage protector

• The level transmitter Micropilot S is equipped with an internal overvoltage protector (600 Vrms surge arrester) according to EN/IEC 60079-14 or EN/IEC 60060-1 (impulse current test 8/20 μs, Î = 10 kA, 10 pulses). Additionally, the device is protected by a galvanic insulation of 500 Vrms between the power supply and the (HART) current ouput. Connect the metallic housing of the Micropilot S to the tank wall or screen directly with an electrically conductive lead to ensure reliable potential matching.

• Installation with additional overvoltage protector HAW560Z/HAW562Z (see XA00081F "Safety instructions for electrical apparatus certified for use in explosionhazardous areas"). – Connect the external overvoltage protector and the Micropilot S transmitter to the local

potential matching system. – Potentials shall be equalised both inside and outside the explosion hazardous area. – The cable connecting the overvoltage protector and the Micropilot S transmitter shall

not exceed 1 m (3.3 ft) in length. – The cable shall be protected e.g. routed in an armoured hose.

Power supply

• For stand alone operation via two Endress+Hauser RN221N.

• Integrated in tank gauging system via Endress+Hauser Tank Side Monitor NRF590 (recommended operation mode).

Highly accurate measurement

For highly accurate measurements the measured variable must be transmitted using HART protocol to ensure the necessary resolution.
