• any contingencies or occurences that may arise during installation, use and maintenance of the devices.
• the local safety regulations for which the operating company is responsible including the staff in charge of installation and
maintenance.
Danger due to electrical voltage.
• 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 regulations for electrical equipment.
Risk of injury 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.
Risk of injury due to high fluid temperatures.
• Use safety gloves to handle the device.
• Stop the circulation of fluid and drain the pipe before loosening the process connections.
Risk of injury due to the nature of the fluid.
• Respect the prevailing regulations on accident prevention and safety relating to the use of hazardous products.
Various dangerous situations
To avoid injury take care:
• 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 use the device for the measurement of gas flow rates.
• 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 or internal modifications to the device.
• 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.
• to use the device only if in perfect working order and in compliance with the instructions provided in the operating
instructions.
• to observe the general technical rules when installing and using the device.
NOTE
The device may be damaged by the fluid in contact with.
• 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).
NOTE
Elements / Components sensitive to electrostatic discharges
• This device contains electronic components sensitive to electrostatic discharges. They may be damaged if they are

Description
5. DESCRIPTION
5.1. Area of application
The compact version of the flowmeter type 8025 or 8035 is designed to measure the flow rate of a liquid and to totalise the
volume of a liquid.
The remote version of the flowmeter type 8025 is a transmitter that must be connected to an 8020 or an 8030 flow sensor with
a sinus or a pulse output, only in "Low Power" version.
5.2. General description
The 8025 is a flowmeter available in compact, panel or wall-mounted version. The 8035 is a flowmeter in compact version.
• A compact version of the 8025 is composed of a flow sensor with paddle-wheel and of an electronic module (the electronic
is located in a housing with cover, display and 2 cable glands).
• A compact version of the 8035 is composed of a sensor-fitting type S030, with paddle-wheel and of an electronic module
(the electronic is located in a housing with cover, display and 2 cable glands).
• A panel version of the 8025 is an electronic module (an electronic located in an open housing with display).
• A wall-mounted version of the 8025 is an electronic module (an electronic integrated in a housing with cover, display and 3
cable glands).
According to the version, the device requires a 12-36 V DC or a 115/230 V AC power supply.
The electrical connection is carried out via a male fixed connector or on the terminal blocks of the electronic board: whether
directly, whether via 2 or 3 cable glands.
10
5.3. Measuring principle
The circulation of fluid within the pipe causes the paddle wheel of the sensor to rotate. The flowmeter detects the rotation of
the paddle-wheel and generates a signal which frequency f is proportional to the flow rate Q, using the formula f = KxQ.
f = frequency in Hertz (Hz)
K = K factor of the S020 or S030 fitting used, in pulse/litre
Q = flow rate in litre/second
5.4. Available versions of the 8025 compact flowmeter
All the compact versions of the flowmeter 8025 have:
- a 4-20 mA current output;
- a pulse output ;
- two totalizers.
