2. INTENDED USE

Use of the device that does not comply with the instructions

could present risks to people, nearby installations and the

environment.

The 8041 owmeter is intended exclusively to measure the

ow rate in liquids.

▶Use this device in compliance with the characteristics and

commissioning and use conditions specied in the contrac-

tual documents and in the Operating Instructions.

▶Never use the owmeter type 8041 for security applications.

▶Protect this device against electromagnetic interference,

ultraviolet rays and, when installed outdoors, the eects of

climatic conditions.

▶Protect this device against electromagnetic interference,

ultraviolet rays and, when installed outdoors, the eects of

careful operation and maintenance.

▶Only use the device as intended.

3. BASIC SAFETY INFORMATION

This safety information does not take into account any contin-

gencies or occurrences that may arise during installation, use

and maintenance of the device.

The operating company is responsible for the respect of the local

safety regulations including sta safety.

Risk of injury due to high pressure in the installation.

▶Stop the circulation of uid, cut o the pressure and drain

the pipe before loosening the process connections.

Risk of injury due to electrical voltage.

▶If a 18...36VDC powered version is installed either in a wet environ-

ment or outdoors, all the electrical voltages must be of max. 35VDC.

▶Shut down the electrical power source of all the conductors

and isolate it before carrying out work on the system.

▶Observe all applicable accident protection and safety regula-

tions for electrical equipment.

Risk of injury due to high uid temperatures.

▶Use safety gloves to handle the device.

▶Stop the circulation of uid and drain the pipe before loosen-

ing the process connections.

Risk of injury due to the nature of the uid.

▶Respect the prevailing regulations on accident prevention

and safety relating to the use of aggressive uids.

Basic safety information

Various dangerous situations

To avoid injury take care:

▶to prevent any unintentional power supply switch-on.

▶to ensure that installation and maintenance work are carried

out by qualied, authorised personnel in possession of the

appropriate tools.

▶to guarantee a dened or controlled restarting of the pro-

cess, after a power supply interruption.

▶not to use the device for the measurement of gas ow rates.

▶not to use the device in explosive atmospheres.

▶not to use the device in an environment incompatible with

the materials it is made of.

▶not to subject the device to mechanical loads.

▶not to make any modications to the device.

▶to use the device only if in perfect working order and in

compliance with the instructions provided in these Operating

Instructions.

▶to observe the general technical rules when installing and

using the device.

NOTICE

The device may be damaged by the uid in contact with.

▶Systematically check the chemical compatibility of the

component materials of the device and the uids likely to

come into contact with it (for example: alcohols, strong or

concentrated acids, aldehydes, alkaline compounds, esters,

aliphatic compounds, ketones, halogenated aromatics or

hydrocarbons, oxidants and chlorinated agents).

NOTICE

Elements / Components sensitive to electrostatic discharges

▶This device contains electronic components sensitive to

electrostatic discharges. They may be damaged if they are

touched by an electrostatically charged person or object.

In the worst case scenario, these components are instantly

destroyed or go out of order as soon as they are activated.

▶To minimise or even avoid all damage due to an electro-

static discharge, take all the precautions described in the

EN61340-5-1norm.

▶Also ensure that you do not touch any of the live electrical

components.

5. DESCRIPTION

5.1. Area of application

The device is used to measure the ow of neutral or slightly

aggressive uids with a conductivity of more than 20µS/cm in

DN06 to DN400 pipes.

5.2. General description

5.2.1. Construction

The device comprises an electronic module and a PVDF or

stainless steel measurement sensor.

The ow sensor comprises two electrodes and a magnetic

system.

The connection of the device to the process is made depending

on the version, either by a G2" nut or a clamp.

Electrical connection is made via two cable glands on a 6-pin

terminal block.

The device requires an 18...36VDC power supply and has:

• a frequency output,

• a relay output,

• a 4...20mA current output.

english

Type 8041

Description

5.2.2. Operating principle

The magnetic system in the ow sensor generates a magnetic

eld in the uid, perpendicular to the ow direction, see Fig.1.

The electrodes on the ow sensor ensure electrical contact with

the uid. When the uid ows over them, a voltage is measured

between the two electrodes. This voltage is proportional to the

uid velocity.
