The Ultrasonic Point Level
System 416X Series is an ideal solution for detecting liquid in compact
spaces. With integrated electronics it
is a direct replacement for Float Switches, Capacitance and Optical Detectors. The GS 416X detects liquid irrespective of change
in density color, dielectric constant or viscosity. The GS 416X does not
require calibration or periodic maintenance.
The sensor is constructed in 316 SS and is available in lengths of up to
99”. ECHO can provide the GS 416X in a variety of engineered plastics to obtain
the ideal corrosion resistance in process vessels.

The GS 416X Series unit consists of two piezoelectric elements mounted between the forks where the presence and absence of liquid is detected. These elements convert electrical energy to mechanical energy in the form of ultrasonic signal detecting the presence of liquid. The ultrasonic signal is attenuated with no liquid present and passes freely across the gap when liquid is present. The Solid State Closed Loop circuit detects the presence and absence of the ultrasonic signal.
