Type 8025 / 8035

Description

5. DESCRIPTION

5.1. Area of application

The compact version of the flowmeter type 8025 or 8035 is designed to measure the flow rate of a liquid and to totalise the volume of a liquid.

The remote version of the flowmeter type 8025 is a transmitter that must be connected to an 8020 or an 8030 flow sensor with a sinus or a pulse output, only in "Low Power" version.

5.2. General description

The 8025 is a flowmeter available in compact, panel or wall-mounted version. The 8035 is a flowmeter in compact version.

• A compact version of the 8025 is composed of a flow sensor with paddle-wheel and of an electronic module (the electronic is located in a housing with cover, display and 2 cable glands).

• A compact version of the 8035 is composed of a sensor-fitting type S030, with paddle-wheel and of an electronic module (the electronic is located in a housing with cover, display and 2 cable glands).

• A panel version of the 8025 is an electronic module (an electronic located in an open housing with display).

• A wall-mounted version of the 8025 is an electronic module (an electronic integrated in a housing with cover, display and 3 cable glands).

According to the version, the device requires a 12-36 V DC or a 115/230 V AC power supply. The electrical connection is carried out via a male fixed connector or on the terminal blocks of the electronic board: whether

directly, whether via 2 or 3 cable glands.

5.3. Measuring principle

The circulation of fluid within the pipe causes the paddle wheel of the sensor to rotate. The flowmeter detects the rotation of the paddle-wheel and generates a signal which frequency f is proportional to the flow rate Q, using the formula f = KxQ.

f = frequency in Hertz (Hz) K = K factor of the S020 or S030 fitting used, in pulse/litre Q = flow rate in litre/second

5.4. Available versions of the 8025 compact flowmeter

All the compact versions of the flowmeter 8025 have:

- a 4-20 mA current output;

- a pulse output ;

- two totalizers.
