				3 Product description
		3.2		Principle of operation
Application area		VEGAPULS C 23 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.
		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)

Ambient conditions

Process conditions

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

4.2 Mounting versions

Mounting bracket

For the wall mounting, a mounting bracket with opening for thread G1

is recommended. The mounting of the device in the bracket is carried

out via the supplied G1 counter nut of plastic. Take note of chapter "

Mounting instructions" for the recommended distance to the wall.

> 200 mm (7.87")

	4 Mounting
	4.3 Mounting instructions
Polarisation	Radar sensors for level measurement emit electromagnetic waves.
	The polarization is the direction of the electrical component of these
	waves.
	The position of the polarisation is in the middle of the type label on the
	instrument.

Fig. 6: Position of the polarisation

1 Middle of the type label

Note:

When the device 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.

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

" 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. 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.

	4 Mounting
Nozzle	For nozzle mounting, the nozzle should be as short as possible and
	its end rounded.This reduces false reflections from the nozzle.
	The antenna edge should protrude at least 5 mm (0.2 in) out of the
	nozzle.
	<![if ! IE]> <![endif]>≥ 5 mm (0.20")
	Fig. 11: Recommended socket mounting of VEGAPULS C 23
	If the reflective properties of the medium are good, you can mount
	VEGAPULS C 23 on sockets longer than the antenna. The socket end
	should be smooth and burr-free, if possible also rounded.
	Note:
	When mounting on longer nozzles, 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 spi-

rals, 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.

4 Mounting

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.13:Cover flat, large-area profiles with deflectors

Alignment - Liquids

In liquids, direct the device as perpendicular as possible to the me-

dium surface to achieve optimum measurement results.

Fig. 14: Alignment in liquids

Orientation - Bulk solids In order to measure as much of the vessel volume as possible, the device should be aligned so that the radar signal reaches the lowest level in the vessel. In a cylindrical silo with conical outlet, the sensor is mounted anywhere from one third to one half of the vessel radius from the outside wall (see following drawing).

The following table shows the necessary angle of inclination. It depends on the measuring distance and the distance "a" between vessel centre and installation position.

Example:

In a vessel 20 m high, the installation position of the sensor is 1.4 m from the vessel centre.

The necessary angle of inclination of 4° can be read out from this table.

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.
