ACD-201L Static-Pressure Liquid Level Meter

Short Description:

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 directly 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.
