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
(such as transmitter type 8025 Universal or batch controller type 8025
Batch) 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.
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.
