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 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 elec-
trostatic discharge, take all the precautions described
in the EN 61340-5-1 and 5-2 norms.
• Also ensure that you do not touch any of the live elec-
trical components.

DescripTion

Area of application
The 8020 flowmeter is intended to measure the flow rate of
neutral or slightly aggressive liquids free of solid particles.
construction
The device is made up of an electronic module and of a flow
sensor. The device can be installed in any pipe from DN20
(except for DN20 specified p. 27) to DN400.
The device has, depending on the version, 1 NPN tran-
sistor output, 2 transitor outputs, NPN and PNP, or 1 sinus
output (coil output).
Electrical connection is made via a male fixed connector.
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 fitting used, in pulse/litre
Q = flow rate in litre/second
