300, 1200, 2400, 4800, 9600, 38400, baud rate. 4- Snsr Size AFLO transmitters can be equipped with some different sensors that have deferent diameter of measuring pipes. The pipes in different diameters from 10mm to 3000mm can be chosen in relative table. - Page 18 AFLO-Electromagnetic Flow Meter 8- Flow Direct If users think the direct and design are different, just change the direct parameter is OK, but not change exciting or signal. 9- Flow zero Make sure the sensor is full of fluid, and the fluid is stable. Flow zero is shown as velocity of flow, mm/s.
- Page 19 AFLO-Electromagnetic Flow Meter 13- Output currents Output current types can be chosen by users as 1~10mA or 4~20mA practically. 14- Pulse Type Two kinds of Pulse Outputs can be chosen: Frequency Output and Pulse Output. Frequency Output is continuous square waveform and Pulse output is a serial wave of square wave. Frequency output is mainly used for instant flow and total integrated flow in short time measurement.
- Page 20 Sensor Coefficient Parameter when it runs with converter. 25- Field Type AFLO affords three exciting frequency types: 1/16 frequency (type 1), 1/20frequency (type 2), 1/25 frequency (type 3). The small-bore one should use 1/16 frequency, and large-bore one should use 1/20 or 1/25 frequency.
- Page 21 This coefficient can select the width of time of restrain cuspidal disturb and the unit is ms. If the duration is shorter than flow change in some time, AFLO will think it is cuspidal disturb, and if it is longer, AFLO will think it is natural.
