The SD memeroy data logger is specially designed for Abest’s transit-time series ultrasonic flow meters. Users can order it if have such request. The SD data logger will record data outputed by the internal SerBUS port of ultrasonic flow meters as customers’ setting. Please kindly note if a thermal printer have been already connected to the SerBUS port of ultrasonic flow meters, users need to built a power switch to control the printer. By this controlling, it can avoid printing out all of the data sent to the SD data logger.
The SD data logger doesn’t need special external power supply, and it steals 3.3VDC power from the ultrasonic flow meters.
The SD data logger mainly include the following items,
1)A data logger processing unit
2)A SD flash memory card
3)A triple-core connection wire
4) A SD flash memory card reader

Working process expression
After connecting to the SerBUS port and making the setting above, a file name of PRIN.TXT will be created automatically by the SD data logger process unit. If the name file has been existed in the data logger, the processing unti won’t overwrite it, and just append the new data entries to the existing file.So the user should delete the existed file of PRINT.TXT by using PC in order to make full use of the storing space of the SD memory.
