DIGITAL BATCH CONTROLLER MyProc MFC 0257 Operation and display: The device can be calibrated by means of the K-factor, or via the TEACH-IN function. Customized adjustments, such as measuring range, engineering units, pulse output and filter are carried out on site. The operation is specified according to three levels: Flow transmitter (compact or remote) Indication in operating mode / Display – dosing amount – dosing mode – main totalizer – daily totalizer with reset function Parameter definition – language – engineering units – K-factor / TEACH-IN function – selection for dosing mode – over-run correction – alarm – function mode of relays – reset main totalizer Test – display of state of binary inputs – relay test – frequency test To scroll-up the menu or increase a value To scroll-down the menu or select a digit to be modified Relay 1 LED* Confirm input and menu points Relay 2 LED* *(option) 38 Meyer Industrie-Electronic GmbH – MEYLE Carl-Bosch-Straße 8 49525 Lengerich/Germany Tel.: +49 54 81-93 85-0 Fax: +49 54 81-93 85-12 Internet: www.meyle.de E-Mail: sales@meyle.de
DIGITAL BATCH CONTROLLER MyProc MFC 0257 Accuracy diagram: Design and principle of operation: The MFC 0257 integrates the electronic board with display, programmation keys and also a transducer (Hall). The paddle-wheel is mounted in the fitting. The output signals are provided via two cable glands. When liquid flows through the pipe, the 4 magnets, inserted in the paddle-wheel set in rotation, produce a measuring signal in the transducer. The frequency modulated induced voltage is proportional to the flow velocity of the fluid. A conversion coefficient (K-factor, available in the MAF 252 instruction manual of the fitting), specific to each pipe (size and material) enables the conversion of this frequency into volume. The electronic component converts the measured signal and displays the actual volume. The MFC 0257 batch controller is mounted in a pipe in series with the valve; the unit controls the opening of the valve and measures the quantity of the fluid which flows. The unit also closes the valve when the pre-programmed quantity has been delivered. The electronic component needs a voltage supply of 12–30 V DC or 115/230 V AC, and two output relays are used to activate the valves and to initiate alarms. The following dosing and filling operations are possible: – Local dosing: the user enters the quantity to be metered and initiates the dosage from the keypad. – Local dosing with pre-set quantity: the user selects a quantity which has been preset and initiates the dosage from the keypad. – Remote control dosing using a rotary knob (selecting a pre-set quantity) or binary data inputs. – Dosing controlled by a PLC unit using binary data inputs. – Automatic dosing controlled by variation of pulse duration. The quantity of the dose is directly proportional to the duration of a pulse.
