Advanced Electronics
For Liquid Level,
Volume or Open
Channel Flow
Available as an integral or remote mounted unit,
this versatile and powerful ultrasonic transmitter
is easy to install and quick to calibrate.
Isolated 4–20 mA output with an active/passive mode for
loop power or device power. RS-485 with Modbus protocol
allows bi-directional communication with DCS or PLC. Two
or four 10 amp SPDT gold flash relays for a wide variety of
alarm and control schemes.
