5. 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 transistor 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
