Description
Type 8025 / 8035
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.
