	3.2 Principle of operation
Application area	VEGAPULS C 11 is a radar sensor for continuous level measurement.
	It is suitable for liquids and solids in virtually all industries, particularly
	in the water and waste water industry.
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 filling height.

3.3 Adjustment

Wireless adjustment	Devices with integrated Bluetooth module can be adjusted wirelessly
	via standard adjustment tools:
	•	Smartphone/tablet (iOS or Android operating system)
	•	PC/notebook with Bluetooth USB adapter (Windows operating
		system)

	The packaging consists of environment-friendly, recyclable card-
	board. For special versions, PE foam or PE foil is also used. Dispose
	of the packaging material via specialised recycling companies.
Transport	Transport must be carried out in due consideration of the notes on the
	transport packaging. Nonobservance of these instructions can cause
	damage to the device.
Transport inspection	The delivery must be checked for completeness and possible transit
	damage immediately at receipt. Ascertained transit damage or con-
	cealed defects must be appropriately dealt with.
Storage	Up to the time of installation, the packages must be left closed and
	stored according to the orientation and storage markings on the
	outside.
	Unless otherwise indicated, the packages must be stored only under
	the following conditions:
	•	Not in the open
	•	Dry and dust free
	•	Not exposed to corrosive media
	•	Protected against solar radiation
	•	Avoiding mechanical shock and vibration

4.1General instructions

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

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

4.2Mounting versions

For a rigid mounting, a mounting bracket with opening for thread G1½, e.g. from the VEGA product range, is recommended. The mounting of the sensor in the bracket is carried out via a G1½ counter nut of plastic. Take note of chapter "Mounting instructions" for the recommended distance to the wall.

> 200 mm

(7.87")

Fig. 4: Mounting via a mounting bracket

4.3Mounting instructions

The emitted radar impulses of the radar sensor are electromagnetic waves. The polarisation is the direction of the electrical wave component. By turning the instrument in the mounting strap, the polarisation can be used to reduce the effects of false echoes.

The position of the polarisation is in the middle of the type label on the instrument.

Installation position

When mounting the sensor, keep a distance of at least 200 mm

(7.874 in) from the vessel wall. If the sensor 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

"Setup").

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.

> 200 mm (7.87")

Fig. 6: Mounting of the radar sensor on round vessel tops

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

Do not mount the instruments in or above the filling stream.Make sure that you detect the product surface, not the inflowing product.

Fig.9:Mounting of the radar sensor with inflowing medium

For socket mounting, the socket should be as short as possible and its end rounded.This reduces false reflections from the socket.

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

ca. 5 mm

Fig. 10: Recommended threaded socket mounting of VEGAPULS C 11

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

VEGAPULS C 11 on sockets longer than the antenna. The socket end should be smooth and burr-free, if possible also rounded.

Note:

When mounting on longer sockets, we recommend carrying out a false signal suppression (see chapter "Parameter adjustment").

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.

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.

Sensor orientation

In liquids, direct the sensor as perpendicular as possible to the prod-

uct surface to achieve optimum measurement results.

4 Mounting

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.

58340-EN-191014

	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 product surface.
	If foams lead to measurement errors, you should use the biggest pos-
	sible radar antennas or sensors with guided radar.
	4.4 Measurement setup - Flow
	In general, the following must be observed while mounting the sensor:
	•	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 measurement can be individually configured for the respective flume via a PC/notebook and PACTware/DTM.The measurement can be individually configured for the respective flume via a PC/notebook and PACTware/DTM.

The following examples serve as an overview for flow measurement.
