Design and measuring principle

• The flow transmitter 8025 in a compact version is made of a transducer with display com-
bined in a housing and a flow sensor. The flow sensor has a built-in paddle-wheel.
The output signals are available at the terminals of a 4-pin EN 175301-803 male fixed
connector or of the terminal strip of the electronic board which can be accessed via two
cable glands.
• The flow transmitter 8025 in a panel-mounted version is a transducer with display which
can be installed on the door of an electric panel. It has to be connected to a flow sensor
8020 or 8030 with sinus or pulse output in a "Low Power" version only.
The output signals are available at the terminals of the terminal strip of the electronic
board, inside the cabinet.
• The flow transmitter 8025 in a wall-mounted version is a transducer with display com-
bined in a housing to be fitted to a wall. It has to be connected to a flow sensor 8020 or
8030 with sinus or pulse output in a "Low Power" version only.
The output signals are available at the terminals of the terminal strip of the electronic
board which can be accessed via three cable glands.
• The flow transmitter 8035 is made of a transducer SE35 and a flow sensor, a fitting S030
with integrated paddle-wheel.
Set in rotation by the flow, the 4 permanent magnets integrated in the vanes of the paddle
generate pulses in the receiver (with sinus output for a sensor with coil and with pulse
output for a sensor with hall) the frequency of which is proportional to the flow speed of the
fluid.
A conversion coefficient, called K factor, specific to each fitting (material and diameter) is
necessary to establish the flow value associated with the measurement.
