XSF-03 flow totalizer is used with flowmeter and does the following function:
Accumulated the total flow of fluid
After convertion, frequency current is output 0~10mA or 4~20mA DC standard signal to regulator, recorder and indicator.
The output pulse signal can be used with the related instrument to do quality totalizer for fluid.
The count unit and volume signal of the counter depends on the flowmeter. It is regulated according to the pulse signal full range frequency when the current output. When the full range frequency within 680Hz~4500Hz, you just need to adjust full-scale potentiometer.
The counter of instrument uses CMOS IC which is good at anti-interference. It is widely used in petrochemical, metallurgy, power station and other departments
