8025 Batch controller INSERTION p. 2/12 Operation and display (common to the various versions) When mounted in a pipe (compact version) or connected to a flowmeter (remote version) in series with one or two valves, the 8025 batch controller makes it possible to carry out a dosing of one or several quantities of liquids. The unit controls the opening of the valves and measures the quantity of the fluid which flows. The unit also closes the valves when the preset quantity has been delivered. The electronic component needs a voltage supply of 12...36 V DC or 115/230 V AC. The device is equipped with 4 digital inputs (DI1 up to DI4), 2 transistor outputs (DO1 configured as a pulse output and DO4 configured as state output, by default), 2 relay outputs (DO2 always configured to control the valve and by default parameterize of * of the batch quantity and DO3 configured as alarm output by default), two volume or mass totalizers and two batch totalizers. The second relay output can be used to activate another valve, to initiate alarms or to generate warnings. The following dosing modes are possible: - Locally started dosing of free quantity: the user enters the quantity to be filled and starts the dosing from the keypad. - Locally started dosing of preset quantity: the user selects a quantity which has been preset and starts the dosing from the keypad. - Locally started dosing of free/preset quantity the user enters the quantity to be filled or selects a quantity which has been preset and starts the dosing from the keypad. - Dosing controlled by a PLC unit the user selects a quantity which has been preset and starts the dosing using binary inputs. - Locally/remote selection of preset quantity and dosing controlled by a PLC unit: the user selects a quantity which has been preset from the keypad or using binary inputs and starts the dosing using binary inputs. - Automatic dosing controlled by variation of pulse duration: the quantity of the dosing is directly proportional to the duration of a pulse. - Remote dosing determined by Teach-In: Teach-In of the dosing quantity using binary inputs. - Local dosing determined by Teach-In: Teach-In of the dosing quantity from the keypad

8025 Batch controller INSERTION COMPACT p. 4/12 The compact batch controller The compact batch controller combines a paddle-wheel flow sensor and an electronic module with a display in an IP65 enclosure. The electrical connection is provided via two cable glands. Bürkert designed fitting S020 ensures simple installation of the Bürkert sensor into pipes from DN20 to DN400. Principle of operation When liquid flows through the pipe, the 4 magnets, inserted in the paddle-wheel set in rotation, produce a measuring signal in the transducer (Hall sensor). The frequency modulated induced voltage is proportional to the flow velocity of the fluid. A conversion coefficient (K-factor, available in the instruction manual of the S020 fitting), specific to each pipe (size and material) enables the conversion of this frequency into a volume or a mass. The electronic component converts the measured signal and displays the actual value of the volume or mass.
