5. DESCRIPTION
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 in Table 2, page 23) 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
