Page 10: Description
(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.
