rate of a liquid and to totalize the volume of liquid.
▶This device must be protected against electromagnetic interfer-
ence, 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 contrac-
tual documents and in the Operating Instructions.

Intended use
Type 8025 / SE35, battery powered
English

▶Do not use the device for the measurement of gas flow rates.
▶Do not use the device in explosive atmospheres.
▶Do not use the device in an environment incompatible with the
materials it is made of.
▶Do not use fluid that is incompatible with the materials the

▶Do not make any external or internal modifications to the device.
▶Prevent any unintentional power supply switch-on.
▶Guarantee a defined or controlled restarting of the process,
after a power supply interruption.
▶Obey the general technical rules.
Warning
Burn injury due to the leakage of the chemicals from the bat-
teries if the batteries are exposed to high temperatures.
▶Respect the operating temperature of the batteries.
note
The device may be damaged by the fluid in contact with.
▶Systematically check the chemical compatibility of the compo-
nent 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 com-
pounds, ketones, halogenated aromatics or hydrocarbons,
oxidants and chlorinated agents).
note
Elements / Components sensitive to electrostatic discharges
▶This device contains electronic components sensitive to electro-
static 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.

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.
note
The device may be damaged because the IP65 protection rating
is not guaranteed if the lateral plugs of the electronic module are
loose.
▶Do not unscrew the lateral plugs.
