Based don Digital Liquid Level Meter of ACD-200L , we increase the remote transmission function which create a model Liquid Level Meter of ACD-201L. By adopting output communication module, RS485 communication, USB communication, (4-20) MA current signal output,  ACD-201L can be redirectly read by monitoring PC through communication software to store , process and report output of the measure data. Signal isolated technology , reduce the interference. Built-in lithium battery can work for 5~8 years. ACD-201L Liquid Level Transmitter can acquire the level data consistently when external power off ( communication function failed because of external power off ). Installation of radial, axial and reel packing are available for choice.
