2. INTENDED USE

Use of the flowmeter that does not comply with the instructions could present risks to people, nearby installations and the environment.

• The 8012 flowmeter is intended exclusively to measure flow rate in liquids.

• This device must be protected against electromagnetic interference, ultraviolet rays and, when installed outdoors, the effects of climatic conditions.

• This device must be used in compliance with the characteristics and commissioning and use conditions specified in the contractual documents and in the user manual.

• Requirements for the safe and proper operation of the device are proper transport, storage and installation, as well as careful operation and maintenance.

• Only use the device as intended.

2.1. Restraints

Observe any existing restraints when the device is exported.

3. BASIC SAFETY INFORMATION

This safety information does not take into account:

• any contingencies or occurences that may arise during assembly, use and maintenance of the devices.

• the local safety regulations that the operator must ensure the staff in charge of installation and maintenance observe.

Danger due to high pressure in the installation. Danger due to electrical voltage. Danger due to high temperatures of the fluid. Danger due to the nature of the fluid.

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 qualified, authorised personnel in possession of the appropriate tools.

• to guarantee a defined or controlled restarting of the process, after a power supply interruption.

Intended use

note

Various dangerous situations

To avoid injury take care:

• to use the device only if in perfect working order and in compliance with the instructions provided in the instruction manual..

• to observe the general technical rules when installing and using the device.

• not to use this device in explosive atmospheres.

• not to use the device for the measurement of gas flow rates.

• not to use fluid that is incompatible with the materials the device is made of.

• not to use this device in an environment incompatible with the materials it is made of.

• not to subject the device to mechanical loads (e.g. by placing objects on top of it or by using it as a step).

• not to make any external modifications to the device. Do not paint any part of the device.

note

• Systematically check the chemical compatibility of the component materials of the device and the fluids 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).

• 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 electrostatic discharge, take all the precautions described in the EN 613405-1 and 5-2 norms.

• Also ensure that you do not touch any of the live electrical components.

5. DESCRIPTION

5.1. Area of application

The 8012 flowmeter with magnetic sensor is intended to measure the flow rate of neutral or slightly aggressive liquids free of solid particles.

The 8012 flowmeter with optical sensor is intended exclusively for measuring the flow rate of liquids that allow the passage of infrared rays.

5.2. General description

5.2.1. Construction

The 8012 flowmeter comprises the SE12 electronics incorporating the measuring paddle-wheel and an S012 fitting allowing the device to be fitted to all types of pipes from DN6 to DN65.

The sensor detects the rotation of the paddle-wheel; it generates a signal in which the frequency f is proportional to the rotation frequency of the paddle-wheel.

The electronic module is fitted with 2 LEDs visible by transparency on the side of the housing:

• A green LED is on when the device is energized (the paddlewheel is not running) and then flashes proportionally to the rotation frequency of the paddle-wheel.

• A red LED signals a malfunction of the flowmeter (see chap.

10.4.1).

English

Type 8012

General information

Depending on the version, the electrical connection is made using a 1 m long cable or a multi-pin M12 fixed connector which position can be adjusted.

Depending on the version, the device is equipped:

• with one pulse output

• or one pulse output and one 4-20 mA current output.

5.2.2. Version with pulse output

On the 16 basic versions of the SE12 module (see chap. 5.5), the NPN pulse output generates a signal with a frequency f proportional to the rotation frequency of the paddle-wheel.

To obtain a flow rate Q, this frequency must be divided by a proportionality factor K according to the following formula:

Q = f/K

General information

5.2.3. Version with pulse output and current output

Pulse output

The characteristics of the pulse output are identical to those on a version with pulse output only. See chap. 5.2.2.

Current output

The current output on the basic versions is connected in sink mode and delivers a current I, an image of the rotation frequency f of the paddle-wheel:

I = 8f/125 + 4

As f = KQ, the flow Q is therefore proportional to this current:

Q: flow rate [litre/s] K: K factor [pulse/litre] l: current [mA]

Flow rate

Current attenuation variations

When the flow varies quickly, the current output signal from your device can be stabilised. On the basic versions, the current variations are slightly attenuated.

Generation of an alarm current (versions with optical sensor only)

On the basic versions, an "alarm" current of 22 mA is generated when the circulation direction of the fluid is the opposite of the direction of the arrow on the side of the housing.

7. INSTALLATION AND WIRING

7.1. Safety instructions

danger

Danger due to high pressure in the installation.

• Stop the circulation of fluid, cut off the pressure and drain the pipe before loosening the process connections.

Danger due to electrical voltage.

• Shut down and isolate the electrical power source before carrying out work on the system.

• Observe all applicable accident protection and safety regulations for electrical equipment.

Danger due to high temperatures of the fluid.

• Use safety gloves to handle the device.

• Stop the circulation of fluid and drain the pipe before loosening the process connections.

Danger due to the nature of the fluid.

• Respect the prevailing regulations on accident prevention and safety relating to the use of aggressive fluids.

Warning

Risk of injury due to non-conforming installation.

• The electrical and fluid installation can only be carried out by qualified and skilled staff with the appropriate tools.

• Install appropriate safety devices (correctly rated fuse and/or circuit-breaker).

Risk of injury due to unintentional switch on of power supply or uncontrolled restarting of the installation.

• Take appropriate measures to avoid unintentional activation of the installation.

• Guarantee a defined or controlled restarting of the process subsequent to the installation of the device.

Warning

Risk of injury if the fluid pressure/ temperature dependency is not respected.

• Take the fluid pressure / temperature dependency into account according to the nature of the material of the fitting used (see Fig. 3Fig. ).

note

The SE12 electronic module and the seal may be damaged when welding the connections to the pipe.

• Before welding to the pipe, unscrew the 4 locking screws on the SE12 electronic module.

• Remove the electronic module.

• Remove the seal.

→ Follow the installation recommendations in chap. 7.2.2. → Weld the connections. → After welding the connections to the pipe, correctly replace the

seal.

→ Properly replace the electronic module. → Tighten the 4 screws in an alternating pattern, applying a torque

of 1.5 Nm.

7.2.3. Installing a device with Clamp connections

→ Follow the installation recommendations in chap. 7.2.1.

• Check that the seals are in good condition.

• Place the seals, that have been chosen depending on the process temperature and fluid, into the grooves of the Clamp connections.

→ Fit the Clamp connections to the pipe using a clamping collar.

7.2.4. Installing a device with flange connections

→ Follow the installation recommendations in chap. 7.2.1.

• Check that the seals are in good condition.

• Insert a seal, that has been chosen depending on the process temperature and fluid, into the grooves of the connections.

Make sure the seal remains in its groove when tightening the flange.
