		3.2 Principle of operation
Application area		VEGAPULS 31 is a radar sensor for non-contact, continuous level
		measurement. It is suitable for liquids and solids in practically all
		industries.
Functional principle		The instrument emits a continuous, frequency-modulated radar signal
		through its antenna.The emitted signal is reflected by the medium
		and received by the antenna as an echo with modified frequency.The
		frequency change is proportional to the distance and is converted into
		the level.

Ambient conditions	The instrument is suitable for standard and extended ambient condi-
	tions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1. It can be used
	indoors as well as outdoors.

Process conditions

Protection against moisture

Note:

For safety reasons, the instrument must only be operated within the permissible process conditions.You can find detailed information on the process conditions in chapter " Technical data" of the operating instructions or on the type label.

Hence make sure before mounting that all parts of the instrument exposed to the process are suitable for the existing process conditions.

These are mainly:

•Active measuring component

•Process fitting

•Process seal

Process conditions in particular are:

•Process pressure

•Process temperature

•Chemical properties of the medium

•Abrasion and mechanical influences

Protect your instrument against moisture ingress through the following measures:

•Use a suitable connection cable (see chapter " Connecting to power supply")

•Tighten the cable gland or plug connector

•Lead the connection cable downward in front of the cable entry or plug connector

This applies mainly to outdoor installations, in areas where high humidity is expected (e.g. through cleaning processes) and on cooled or heated vessels.

Note:

Make sure that during installation or maintenance no moisture or dirt can get inside the instrument.

To maintain the housing protection, make sure that the housing lid is closed during operation and locked, if necessary.

	4.2 Mounting instructions
Polarisation	Radar sensors for level measurement emit electromagnetic waves.
	The polarization is the direction of the electrical component of these
	waves.
	The polarization direction is marked on the housing, see following
	drawing:

Fig. 5: Position of the polarisation 1 Marking of the polarisation

Note:

When the housing is rotated, the direction of polarization changes and hence the influence of the false echo on the measured value.

Please keep this in mind when mounting or making changes later.

Reference plane	The centre of the antenna lens is the beginning of the measuring
	range and at the same time the reference plane for the min./max.
	adjustment, see following diagram:

Fig. 6: Reference plane 1 Reference plane

Installation position	When mounting the device, keep a distance of at least 200 mm
	(7.874 in) from the vessel wall. If the device is installed in the center
	of dished or round vessel tops, multiple echoes can arise. However,
	these can be suppressed by an appropriate adjustment (see chapter
	" Set up").

If you cannot maintain this distance, you should carry out a false signal suppression during setup. This applies particularly if buildup on the vessel wall is expected. In such cases, we recommend repeating the false signal suppression at a later date with existing buildup.

57820-EN-200806

>200 mm (7.87")

Fig. 7: Mounting of the radar sensor on round vessel tops

In vessels with conical bottom it can be advantageous to mount the device in the centre of the vessel, as measurement is then possible down to the bottom.

With threaded connection, the antenna end should protrude at least 5 mm (0.2 in) out of the nozzle.

ca. 5 mm

Fig. 10: Thread mounting

If the reflective properties of the medium are good, you can mount

VEGAPULS 31 on sockets longer than the antenna. The socket end should be smooth and burr-free, if possible also rounded.

You will find recommended values for socket heights in the following illustration or the table. The values come from typical applications. Deviating from the proposed dimensions, also longer sockets are possible, however the local conditions must be taken into account.

Note:

When mounting on longer nozzles, we recommend carrying out a

Vessel installations

The mounting location of the radar sensor should be a place where no

other equipment or fixtures cross the path of the radar signals.

Vessel installations, such as e.g. ladders, limit switches, heating spirals, struts, etc., can cause false echoes and impair the useful echo. Make sure when planning your measuring point that the radar sensor has a " clear view" to the measured product.

In case of existing vessel installations, a false signal suppression should be carried out during setup.

If large vessel installations such as struts or supports cause false echoes, these can be attenuated through supplementary measures.

Small, inclined sheet metal baffles above the installations " scatter" the radar signals and prevent direct interfering reflections.

	Fig.12:Cover flat, large-area profiles with deflectors
Orientation	In liquids, direct the device as perpendicular as possible to the me-
	dium surface to achieve optimum measurement results.

4 Mounting

	Fig. 13: Alignment in liquids
Agitators	If there are agitators in the vessel, a false signal suppression should
	be carried out with the agitators in motion. This ensures that the
	interfering reflections from the agitators are saved with the blades in
	different positions.

Fig. 14: Agitators

Foam generation	Through the action of filling, stirring and other processes in the vessel,
	compact foams which considerably damp the emitted signals may
	form on the medium surface.
	If foams lead to measurement errors, you should use the biggest pos-
	sible radar antennas or sensors with guided radar.

4.3 Measurement setup - Flow

In general, the following must be observed while mounting the device:

•	Mounting the sensor on the upstream or inlet side
•	surfaceInstallation in the centre of the flume and vertical to the liquid
•	Distance to the overfall orifice orVenturi flume
•	Min. distance to the max. height of damming for optimum accu-
	racy: 250 mm (9.843 in) 1)

Detailed project planning data can be found at the channel manufacturers and in the technical literature.

The following examples serve as an overview for flow measurement.

1)	At smaller distances the measuring accuracy is reduced, see "Technical
	data".

	5.1 Preparing the connection
Safety instructions	Always keep in mind the following safety instructions:
	•	Carry out electrical connection by trained, qualified personnel
		authorised by the plant operator
	Warning:
	Only connect or disconnect in de-energized state.
Voltage supply	The data for power supply are specified in chapter " Technical data".
	Note:
	Power the instrument via an energy-limited circuit (power max. 100 W)
	acc. to IEC 61010-1, e.g.
	•	Class 2 power supply unit (acc. to UL1310)
	•	SELV power supply unit (safety extra-low voltage) with suitable
		internal or external limitation of the output current
	Keep in mind the following additional factors that influence the operat-
	ing voltage:
	•	Lower output voltage of the power supply unit under nominal load
		(e.g. with a sensor current of 20.5 mA or 22 mA in case of fault)
	•	Influence of additional instruments in the circuit (see load values in
		chapter " Technical data")
Connection cable	Use cable with round cross section for instruments with housing and
	cable gland.To ensure the seal effect of the cable gland (IP protection
	rating), find out which cable outer diameter the cable gland is suitable
	for.
	The instrument is connected with standard two-wire cable. If electro-
	magnetic interference is expected which is above the test values of
	EN 61326-1 for industrial areas, shielded cable should be used.
	Note:
	Shielded cable generally necessary in HART multidrop mode.
	Note:
	If the temperatures are too high, the cable insulation can be dam-
	aged. Hence keep apart from the ambient temperature also the self-
	heating of the instrument for the temperature resistance of the cable
	in the connection compartment in mind 2).
Cable screening and	We recommend to connect the cable screening to ground potential at
grounding	one end on the supply side when using shielded cable.

2)	With an ambient temperature ≥ 50 °C (122 °F) the connection cable should
	be suitable for a temperature which is at least 20 °C (36 °F) higher.

5 Connecting to power supply

Cable gland	Metric threads
	In the case of instrument housings with metric thread, the cable gland
	is screwed in at the factory. It is sealed with plastic plugs as transport
	protection.
	You have to remove this plug before electrical connection.

NPT thread

In the case of instrument housings with self-sealing NPT threads, it is not possible to have the cable entry screwed in at the factory. The cable gland is therefore covered with a red dust protection cap as transport protection.

Note:

To ensure the housing protection class, you must replace this protective cap with an approved NPT cable gland before setup.

Note:

Do not use grease when screwing in the NPT cable gland or a conduit steel pipe.

Maximum torque see chapter " Technical data".

5.2 Connecting

Connection technology The voltage supply and signal output are connected via the springloaded terminals in the housing.

Note:

Fixed conductors and flexible conductors with ferrules can be inserted directly into the terminal openings.In the case of flexible conductors for opening the terminals, use a screwdriver (3 mm blade width) to push the actuator lever away from the terminal opening. When released, the terminals are closed again.
