ACD-302L Static-Pressure Liquid Level Transmitter

Short Description:

Based on years of technical experience of independent research and development of ANCN brand intelligent instruments in the past, we make the Digital Static-Pressure Liquid Level Meter of ACD-302L. This instrument not only has the transmitter function of (4 ~ 20) MA analog signal output, but also can increase the function of RS485 digital communication. Matched with the communication software, ACD-302L can be directly communicated with computer or other communication interface for data acquisition, and the detecting data preservation, processing and report output. It adopts the most advanced micro power consumption devices and improved software technology. Its 5 digits LCD backlight features makes it very rare outstanding one among the Liquid Level Transmitters.
