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.

English

Fig. 1: Running/displacement of oval rotors

The remote instrument converts the frequency into a flow rate by using the correct K factor.
