5 DESCRIPTION
5.1 Area of application
The device is intended to measure, thanks to its oval rotors, the flow
rate of viscous fluids. It must be combined with a remote instrument
(refer to data sheet of the type 8077) which converts the pulse
frequency due to oval rotors rotation.
5.2 General description
5.2.1 Construction
The device is built of a fitting which includes oval rotors and of a
cover including the electronic module with Hall effect sensor and
Reed switch.
The oval rotors of the fitting contain magnets.
All the device versions provide an NPN transistor output and a Reed
switch output.
The electrical connection is made by a 1 meter 5-wire cable.
English

8
Description
Type 8077
5.2.2 Measuring principle
When the fluid flows through the pipe, the oval rotors which contain
magnets turn (see Fig. 1). The displacement of magnets lead to
a variation of magnetic field. The sensor measures the variation of
the magnetic field and converts the signal into a frequency. The
frequency is available at both the NPN transistor and Reed switch
outputs.
Fig. 1 Running/displacement of oval rotors
The remote instrument converts the frequency into a flow rate by
using the correct K factor.

If the device is combined with an instrument which does not
automatically convert the K factors, make the conversion
using one of the following formulae:
K factor in pulse/gallon US = K factor in pulse/l x 3,785 to
obtain flow rate in gallon US / time unit
