2.2 Design and Measuring Principle

Design
The flow transmitter type 8035 consists of
an electronic IP65 housing Type SE35 set
by quarter turn on the fitting S030. The
electronic housing integrates the electronic
board with display, programmation keys and
also a the transducer (coil). The paddle-
wheel is mounted in the fitting..
The transducer component converts the
measured signal and displays the actual
value.
The output signals are provided via a 4-
pole plug or via one PG 13.5 (version without
relay) or via two PG 13.5 (version with
relays).
FLOW TRANSMITTER 8035
Measuring Principle
When liquid flows through the pipe, 4
magnets inserted in the paddle-wheel set in
rotation produce a measuring signal in the
8035 transducer.
The frequency modulated induced voltage
is proportional to the flow velocity of the fluid.
A conversion coefficient, specific to each
pipe (size and material) enables the
conversion of this frequency into flowrate.
This coefficient (Factor-K in pulse/liter) is
available in the instruction manual of the
inline fitting (S030).
The transducer without relay functions in a
2-wire circuit and requires a power supply
of 12...30 VDC. A 4...20 mA standard signal
is available as output signal, proportional to
the flow rate. A pulse output with transistor
open collector NPN/PNP or relay Reed
(option) is available.
The transducer with two additional relays
functions in a 3-wire circuit. Limit values are
freely adjustable (not available with relay
Reed option).
The flow transmitter 8035 measures a flow
rate from 0.3 m/s (1.0 ft/s).
The flow transmitter electronic module type
SE35 can receive a power supply 230/115
VAC as an option.
